摘要：大部分循环冷却水系统使用的是磷系水处理剂，但含磷废水的排放会污染水环境，破坏生态平衡。为达到排放标准，根据循环水系统的水质特点，配合使用无磷药剂。既减轻了循环水处理压力，又节约了循环水排放的处理成本。

随着世界工业的发展以及水资源的匮乏，工业循环水处理日渐成为石化、能源、冶金、电力等行业重要的生产环节。由于在工业用水中工业循环冷却水约占工业用水的 70% ~ 80%，故减少循环冷却水用水量能有效节约工业用水。
循环冷却水在运行过程中不可避免地对换热设备产生了诸如水垢、污垢的沉积、腐蚀的加剧、菌藻的滋生等一系列的危害，如不进行有效治理，循环冷却水系统则很难正常运行。为了控制循环冷却水系统内由水质引起的结垢、污垢、菌藻和腐蚀，保证换热机组的换热效率和使用年限，应对循环冷却水进行处理。
先来看看循环水系统中常见问题有：水垢析出和附着；管道和设备腐蚀；微生物滋生和粘泥；悬浮物导致污垢沉积；高温换热器结垢。
循环水处理主要为结垢控制、腐蚀控制和微生物控制3个方面，来控制循环水中常见问题的。
目前，采用的缓蚀阻垢剂大多为磷系配方，会对环境造成二次污染。随着环境保护意识的提高，低磷或无磷药剂的研发受到广泛关注，它不仅可减少磷排放，保护环境，同时可降低循环水系统的磷酸盐沉积。
无磷药剂在以高碱度、高硬度、高 cod、高氨氮水为补水的循环水系统中得到成功应用，循环水系统的腐蚀、结垢及微生物滋生均得到有效控制。无磷药剂的应用在一定程度上解决了排水对水环境的污染问题，应用无磷药剂后，排水可以达到排放标准。中水回用大幅度降低了新鲜水消耗量，达到了节水的目的。

abstract: most circulating cooling water system water treatment agent is phosphorus, a phosphorus-containing wastewater discharged but will pollute the water environment, destroying the ecological balance. to meet emission standards, according to the characteristics of quality of the circulating water system, with the use of phosphorus-free agent. both to reduce the circulating water pressure, but also save the cost of processing recycled water emissions. keywords: water reuse; phosphate-free agents; circulating water treatment industry with the lack of development of the world as well as water, industrial circulating water treatment is becoming petrochemical, energy, metallurgy, electric power and other industries important production processes. since the industrial cooling water in the industrial water in about 70% to 80% of industrial water, and therefore reduce the circulating cooling water industrial water save water effectively. circulating cooling water during operation of the heat transfer equipment is inevitably produced a series of hazards such as scale, dirt deposition, increased corrosion, bacteria and algae breeding, etc., is not as effective treatment, cooling water system is difficult normal operation. in order to control the fouling of circulating cooling water system caused by water quality, dirt, bacteria and algae and corrosion, the heat exchange efficiency of the heat exchanger unit to ensure the service life and, to deal with circulating cooling water treatment. let's look circulating water system common problems are: the scale deposition and adhesion; corrosion of pipelines and equipment; the growth of microorganisms and slime; suspension cause scale deposition; high-temperature heat exchanger fouling. circulating water treatment mainly for scale control, corrosion control and microbial control three aspects, to control the common problems of circulating water. currently, corrosion and scale inhibitor used mostly phosphorus formula, causing secondary pollution on the environment. with the improvement of environmental awareness, low-phosphorus or phosphorus-free pharmaceutical research and development attracted widespread attention, it can not only reduce phosphorus emissions, protect the environment, while reducing the phosphate deposition of circulating water system. phosphorus agent has been successfully applied to high alkalinity, high hardness, high cod, high ammonia water replenishment circulating water systems, corrosion, fouling and microbial breeding circulating water system have been effectively controlled. application of phosphorus agents to some extent, solve the problem of pollution and drainage of the water environment, the application of phosphorus agents, drainage can meet emission standards. water reuse significantly reduce fresh water consumption, to achieve the purpose of saving water.
