金属表面处理是美化金属表面并进一步改变金属表面的机械性质及物理化学性质等的各种操作过程，较终使得金属制品更加美观、耐腐蚀、耐用。目前主流的表面处理工艺有酸洗、磷化、发黑、电泳、喷涂等，在金属表面处理的过程中会产生部分废水，其污染因子各不相同： 
      酸洗是利用酸溶液去除钢铁表面上的氧化皮和锈蚀物的清洁方法，主要用于工艺的前处理或中间处理。废水主要来自于酸洗后的清洗废水，呈酸性，且含有较高浓度的金属离子，主要污染因子为金属离子、pH、CODcr、石油类、SS； 
      磷化是一种化学与电化学反应形成磷酸盐化学转化膜的过程，给基体金属提供保护，用于涂漆前打底。该类废水主要来自于镀件的清洗废水以及少量的磷化液，污染因子为pH、CODcr、BOD、磷酸盐、SS； 
      发黑是使金属表面产生一层氧化膜，以隔绝空气，达到防锈目的。废水主要来自于工件的冲洗废水，因发黑液的主要成分是氢氧化钠和亚硝酸钠，故废水呈碱性，主要污染因子为pH、CODcr、BOD、金属离子、SS； 
      电泳是电泳涂料在电压作用下，带电荷的涂料离子移动到阴极，并与阴极表面所产生的碱性物质作用形成不溶解物，沉积于工件表面。该类废水主要来自冲洗镀件表面的废水以及少量废弃的电泳液，**物含量高，可生化性较差，呈酸性，主要污染因子为pH、CODcr、金属离子、BOD、SS； 
      喷涂是通过喷枪或碟式雾化器，借助于压力或离心力，分散成雾滴施涂于被涂物表面的涂装方法。涂装废水呈酸性且含有多种金属离子和非金属离子，有些为一类毒物，主要污染因子为pH、CODcr、BOD、金属离子、SS。 
      金属表面处理废水污染物种类较多，水质、水量波动较大，工程、工艺设计时需对源头废水进行分流，并对高浓度废液进行分质预处理，以提高后续处理工艺的稳定性，进而确保废水处理稳定达标排放。

Metal surface treatment is a process to beautify the metal surface and further change the mechanical properties and physical and chemical properties of the metal surface, and ultimately make the metal products more beautiful, corrosion resistant and durable. At present, the mainstream surface treatment processes include pickling, phosphating, blackening, electrophoresis, spraying and so on. During the process of metal surface treatment, some wastewater will be generated, and the pollution factors will be different.
Acid pickling is a cleaning method for removing the oxide and rust on the surface of steel by acid solution, which is mainly used for pretreatment or intermediate treatment of the process. The wastewater mainly comes from the washing wastewater after acid washing. It is acidic and contains high concentration of metal ions. The main pollution factors are metal ions, pH, CODcr, petroleum and SS.
Phosphating is a process of chemical and electrochemical reaction to form a phosphate chemical conversion film, which provides protection to the matrix metal and is used before the paint. The wastewater mainly comes from the cleaning wastewater of plating parts and a small amount of phosphating liquid. The pollution factors are pH, CODcr, BOD, phosphate and SS.
Blackening is to make a layer of oxide film on the surface of the metal to cut off the air and achieve the purpose of antirust. Waste water is mainly from the washing wastewater of workpieces. The main components of black liquor are sodium hydroxide and sodium nitrite, so the wastewater is alkaline. The main pollution factors are pH, CODcr, BOD, metal ions and SS.
Electrophoresis is electrophoretic coating. Under the action of voltage, the charged paint ions move to the cathode, and form an insoluble substance with the alkaline substance produced on the cathode surface, and deposit on the surface of the workpiece. The wastewater mainly comes from the waste water from washing parts and a small amount of waste electrophoretic solution. It has high organic content and poor biodegradability. It is acidic. The main pollution factors are pH, CODcr, metal ions, BOD and SS.
Spraying is a method of coating the spray on the surface of the coated material by means of a spray gun or a disc atomizer, with the help of pressure or centrifugal force. The coating wastewater is acidic and contains many metal ions and non-metallic ions. Some of them are toxic. The main pollution factors are pH, CODcr, BOD, metal ions and SS.
The metal surface treatment of wastewater pollutants more, water quality, water fluctuations, engineering, process design for wastewater source shunt, and the high concentration wastewater pretreatment to improve the quality and stability of the follow-up process, thus ensuring the stability of wastewater discharge standard.
