Introduction
简介
The growth of the Chinese economy over the past 10 to 15 years has been nothing short of phenomenal. In fact, that growth has been so significant that some economists have predicted that China’s economy will become larger than that of the United States by the year 2017, which would make it the most valuable in the world.
过去10-15年中，中国经济的快速增长并不是一种短期现象。事实上，增长之快使有些经济学家预测，到2017年，中国的经济规模将超过美国，成为世界上最大的经济体。
However, this growth, combined with a population that now exceeds 1.34 billion people, does not come without its challenges, namely that it places an immense amount of pressure and strain on the country’s infrastructure. A key component of China’s infrastructure is the country’s municipal and industrial water consumption, usage and treatment. Water is not only the foundation of life, but also the lifeblood of many industries, with readily available water sources a must to guarantee the viability of both the population and the country’s industrial base.
然而这种伴随着超过13.4亿人口的增长，并非没有挑战，主要是对国家的基础设施带来了巨大的压力。中国的基础设施的关键组成部分之一就是市政和工业水消耗、水处理。水不仅是生活的必需品，也是许多行业得以生存的血液。中国的基础设施必须要为人口和工业需求提供充分的供水保证。
How to properly handle and treat water, therefore, is a prime concern throughout the country. This white paper will focus on how one pumping technology— specifically Mechanically Actuated Diaphragm Metering Pumps from Neptune™ Chemical Pump Co.—offers the ultimate in reliability, efficiency, safety, cost-effectiveness and environmental sensitivity in critical Chinese water/ wastewater treating and handling applications.
因此，如何适当地进行水处理成为整个国家关心的问题。本白皮书着重于如何采用泵送技术——特别是海王星化学泵有限公司提供的机械驱动隔膜计量泵——为中国严峻的供水、污水处理和输送应用带来非常可靠、高效、安全、经济和环保的解决方案。
The Challenge
挑战
China has two distinct challenges, which are definedby distinct regions, when it comes to maximizing the effectiveness of its water/wastewater supply and treatment operations:
在说到提升供水/废水处理操作的有效性时，中国在两个地区面临两大不同的挑战：
•In northern China there is a worrying lack of fresh water, so the government encourages the use of recycled water where possible in municipal and industrial applications. This makes the handling and use of “graywater” a front-of-mind topic in that part of the country. Graywater is wastewater that is generated from domestic activities such as laundry, dishwashing and bathing. This wastewater differs from that which comes from toilets, which is termed sewage or “blackwater” since it contains human waste. Most graywater is easy to treat if it is collected separately from the blackwater. In fact, domestic graywater, if handled properly, can be recycled directly within the home, garden or company and used either immediately or processed and stored. This is how the Chinese government is recommending that graywater be handled and used.
在北方，担心的是缺乏淡水，因此在市政和工业用水中，政府鼓励使用循环水。这使得“灰水”的处理和利用成为中国北方地区的首要问题。灰水是指由于居民生活所产生的废水，包括洗衣、洗碗、淋浴等。这种废水不同于来自厕所的污水，或称为“黑水”。事实上，通过与黑水分开收集，居民生活产生的灰水，如果加以适当的处理，可以立即或经处理和贮存后直接循环利用，供家庭、花园和公司使用。这是中国政府对灰水处理和使用的建议。
•In the southern part of the country there is more readily available water, but there is also a higher level of population growth and industrial operations. This results in a higher level of polluted water that is produced and a very high focus on the efficient treatment of this wastewater, again with the goal of recycling and reusing it where possible.
在南方，淡水相对更为充足，但人口增长和工业发展也较快。这就导致了水质污染更严重，南方地区的水处理重点在提高废水处理的效率，其目的也是为了尽可能地循环使用。
Because of nationwide concerns regarding water availability and its level of cleanliness, the Chinese government has imposed stricter regulations on the water treatment industry. For example, today all water that is used in general industrial applications, the municipal market or in power generation operations must be recycled for reuse. While this creates a massive opportunity for expansion in the water-treatment market—with consistent growth expected for the next 10 to 20 years, and revenues ranging from 元63.6 billion to 元127.1 billion (US$10 billion to US$20 billion) annually—it also places pressure on the companies that treat water and wastewater, along with the industries that consume it, to identify and incorporate pumping technologies that deliver the highest levels of reliability, efficiency, safety, maintenance-free operation and environmental friendliness.
由于整个国家都存在对水的供应和清洁程度的担心，中国政府对水处理行业已实施了更为严格的法规。例如，今天所有一般工业应用、市政或发电厂中所使用的水，必须循环利用。这就使水处理市场规模扩大，带来了巨大机会。根据预计的增长速度，在未来的10-20年中，年产值将从636亿元增长到1271亿元（约100亿美元至200亿美元）。这也对供水和废水处理公司，乃至用水的所有行业带来了巨大的压力，要找到并采用具有最大可靠性、高效性、安全性、免维护及环保性的泵送技术。
The Solution
解决方案
One of the key applications within water and wastewater treatment activities is the dosing and injection into the water stream of various chemicals that are used to clean and treat the water. The technology that has proven to be most efficient and reliable in these crucial applications is the mechanically actuated diaphragm metering pump.
在供水和废水处理操作中的一个关键应用是向水中添加各种化学品，用以清洁和处理水体。经证明最高效可靠的技术就是采用机械驱动的隔膜计量泵。
Since 1961, Neptune Chemical Pump Co., which is headquartered in North Wales, PA, USA, and a founding member of the Dover Corporation’s Pump Solutions Group (PSG?), Oak Brook Terrace, IL, has been recognized as one of the leading global experts in metering-pump technology.
自1961年以来，总部设在美国宾夕法尼亚州North Wales，都福集团麾下美国百士吉泵业集团（PSG®）（总部位于美国伊利诺州Oakbrook Terrace）的发起成员，海王星化学泵有限公司就一直被公认为计量泵技术的全球领头羊。
Specifically, Neptune is offering its 7000 Series Mechanically Actuated Diaphragm Metering Pumps to the Chinese water and wastewater markets. Neptune buttressed its commitment to the market with its announcement in early 2012 that it would begin manufacturing the 7000 Series pumps at PSG China’s manufacturing facility in Shanghai.
特别值得一提的是，海王星针对中国供水和废水市场推出了7000系列机械驱动隔膜计量泵。海王星公司在2012年初宣布将在中国上海的工厂生产7000系列泵，以此实现其对中国市场的承诺。
Neptune’s 7000 Series pumps are mechanically actuated and have been designed to handle clear liquids and chemicals with viscosities ranging from water-like to 1,500 cPs (7,000 ssu), which makes them ideal for use in municipal and industrial water/wastewater treatment, as well as in other industries such as agriculture, chemical feed/processing, mining, chemigation/fertigation, power generation, processing and gas odorization.
海王星7000系列泵为机械驱动，专为处理澄清液体和粘度从水样到1,500 cPs（7,000 ssu）的化学品所设计，使之成为市政和工业供水/废水处理，以及其他行业，包括农业、化学加料/加工、采矿、化学灌溉/滴灌施肥、发电、加工工业和气体脱臭的理想选择。
This operational versatility is borne in the fact that the mechanical design of the 7000 Series pumps eliminates the use of contour plates on the liquid side of the diaphragm. Combined with a straight-through valve and head configuration, this results in the pump being able to deliver more consistent and reliable flow and dosing rates.
这种操作上的多用性源于7000系列泵的机械设计中消除了隔膜接液侧所使用的压型板。结合直通阀和泵头配置，使得泵可以提供更恒定可靠的流量和加剂率。
Additionally, the flow capacity of the 7000 Series pumps is manually adjustable via a micrometer dial while the pump is running. This allows the pump to produce flow rates ranging from 38 L/hr to 1,710 L/hr (10 gph to 450 gph) at head pressures up to 10 bar (150 psi).
此外，7000系列泵的流量可以在泵运行的同时采用手动拨盘调节，使得泵的流量可以在38 L/hr到 1,710 L/hr（10 gph到450 gph）之间调节，泵头压力最高可达10 bar（150 psi）。
Currently, Neptune is offering its 7000 Series pumps to the Chinese water/wastewater market with liquid heads constructed of PVC, since that is the most common request from end-users, but it will also be offering pumps with PVDF and stainless steel in the future, which will expand the range of chemicals that the pumps can be used with. All 7000 Series pumps are self-priming and also provide superior performance when pumping chemicals such as sodium hypochlorite, which can off-gas. The 7000 Series pumps are driven by a standard Neptune gearbox and motor with explosion-proof, variable-frequency drive and wash-down duty motor options also available.
目前，海王星向中国供水/废水处理市场所提供的7000系列泵为PVC泵头，因为这是最终用户最普遍需求的型号，未来还将提供PVDF材质和不锈钢材料的泵头，从而扩大泵可以输送的化学品范围。所有7000系列泵都具有自吸性，在泵送次氯酸钠（可能会释放出气体）时具有出色的性能。7000系列泵由标准海王星齿轮和马达驱动，也可选配防爆、变频、可水洗的马达。
The 7000 Series mechanically actuated diaphragm metering pumps from Neptune are ideal for applications involving sodium hypochlorite found in the water and wastewater industries. There are four model families within the 7000 Series: the 7500, which has a 100-mm (4-in.) diaphragm diameter with speeds from 37-232 strokes per minute (spm); the 7600, which features a 150-mm (6-in.) diaphragm diameter and 37-232 spm; the 7700, with a 200-mm (8 in.) diaphragm diameter and 58-176 spm; and the 7800, which offers a 250-mm (10 in.) diaphragm diameter and 58-176 spm. Neptune is offering a three-year warranty on all models within its 7000 Series.
海王星的7000系列机械驱动隔膜计量泵是供水和废水行业中常用的次氯酸钠应用的理想选择。7000系列中有四个型号：7500型，隔膜直径为100毫米（4英寸），速度为每分钟37-232个冲程；7600型，隔膜直径为150毫米（6英寸），速度为每分钟37-232个冲程；7700型，隔膜直径为200毫米（8英寸），速度为每分钟58-176个冲程；7800型，隔膜直径为250毫米（10英寸），速度为每分钟58-176个冲程。海王星公司对7000系列的所有型号都提供三年质保。
Conclusion
结论
The Chinese system of fengshui—whose literal Englishtranslation is “wind-water”—is a system of spatial lawsthat are considered to govern arrangement and orientationin relation to the flow of energy, known as “qi.” Withinfengshui, the presence and use of water, which should beflowing and not stagnant, is meant to help the balance,harmony and prosperity in one’s life.
中国的风水理论就是一种有关空间关系的理论，风水控制着气的分布和方向。在风水中，水的存在和使用应该是顺其流而不能受阻，从而有助于人生的平衡、和谐和兴旺。
The overall fengshui of the Chinese population andindustry relies on a constant flow of clean, healthywater. With both the population and the industrialbase continuing to grow at accelerated rates, delivering n adequate supply of water is of the utmost concernfor the Chinese government. That is spelled out in theincreasingly strict regulations that govern the watersupply’s availability, use, recycling and reuse.
中国人口和工业的风水依赖于清洁、健康的水的源源流动。随着人口和工业的加速发展，保证充足的供水是中国政府最为关心的头等大事。这体现在对供水、用水、水循环和再利用的日益严格的法规中。
