金屬表面處理是美化金屬表面并進一步改變金屬表面的機械性質及物理化學性質等的各種操作過程，較終使得金屬制品更加美觀、耐腐蝕、耐用。目前主流的表面處理工藝有酸洗、磷化、發黑、電泳、噴涂等，在金屬表面處理的過程中會產生部分廢水，其污染因子各不相同： 
      酸洗是利用酸溶液去除鋼鐵表面上的氧化皮和銹蝕物的清潔方法，主要用于工藝的前處理或中間處理。廢水主要來自于酸洗后的清洗廢水，呈酸性，且含有較高濃度的金屬離子，主要污染因子為金屬離子、pH、CODcr、石油類、SS； 
      磷化是一種化學與電化學反應形成磷酸鹽化學轉化膜的過程，給基體金屬提供保護，用于涂漆前打底。該類廢水主要來自于鍍件的清洗廢水以及少量的磷化液，污染因子為pH、CODcr、BOD、磷酸鹽、SS； 
      發黑是使金屬表面產生一層氧化膜，以隔絕空氣，達到防銹目的。廢水主要來自于工件的沖洗廢水，因發黑液的主要成分是氫氧化鈉和亞硝酸鈉，故廢水呈堿性，主要污染因子為pH、CODcr、BOD、金屬離子、SS； 
      電泳是電泳涂料在電壓作用下，帶電荷的涂料離子移動到陰極，并與陰極表面所產生的堿性物質作用形成不溶解物，沉積于工件表面。該類廢水主要來自沖洗鍍件表面的廢水以及少量廢棄的電泳液，有機物含量高，可生化性較差，呈酸性，主要污染因子為pH、CODcr、金屬離子、BOD、SS； 
      噴涂是通過噴槍或碟式霧化器，借助于壓力或離心力，分散成霧滴施涂于被涂物表面的涂裝方法。涂裝廢水呈酸性且含有多種金屬離子和非金屬離子，有些為一類毒物，主要污染因子為pH、CODcr、BOD、金屬離子、SS。 
      金屬表面處理廢水污染物種類較多，水質、水量波動較大，工程、工藝設計時需對源頭廢水進行分流，并對高濃度廢液進行分質預處理，以提高后續處理工藝的穩定性，進而確保廢水處理穩定達標排放。

The company has a number of professional technical teams and strict and effective management system, and is committed to the professional manufacture of environmental water treatment equipment. In the past few years, the company has made great progress, and has been cooperating with the famous professional institutions in China. It has strong non standard design, manufacturing and service ability, the production inspection equipment is perfect, the variety specification is complete, the product quality is stable and reliable.
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.
