Abstract

The invention relates to the field of wastewater treatment, and particularly relates to an oil-containing electroplating wastewater treatment method. The method is characterized in that the system comprises an oil-containing wastewater regulating tank (900), an oil-containing sedimentation tank (901), an oil-containing coagulation reaction sedimentation tank (902), an oil-containing intermediate water tank (903), an oil-containing wastewater A / O biological reaction tank (904), an oil-containing wastewater secondary sedimentation tank (905), a discharged wastewater regulating tank (906) and anoil-containing sludge tank (907); the oil-containing wastewater regulating tank (900), the oil-containing sedimentation tank (901) and the oil-containing coagulation reaction sedimentation tank (902)are sequentially connected in series through pipeline valves; and the oil-containing coagulation reaction sedimentation tank (902) is divided into two paths, one path is connected with the oil-containing intermediate water tank (903), and the other path is connected with the oil-containing sludge tank (907). The device and the method can be used for accurately treating various electroplating wastewater.

Description

[0001] This case is a divisional application with the title of the invention "a system for the separation and treatment of electroplating wastewater in centralized control areas", the application number "2019114081810", and the application date "2019-12-31". technical field [0002] The invention relates to the field of wastewater treatment, in particular to a method for treating oily electroplating wastewater. Background technique [0003] The wastewater output of the electroplating industry is less than that of papermaking, printing and dyeing, and chemical industries. However, due to the wide distribution of electroplating factories, there are many types of harmful substances contained in electroplating wastewater. Therefore, the treatment of electroplating wastewater is very important. Electroplating wastewater mainly contains chromium, zinc, copper, lead, nickel and other heavy metal ions, as well as carcinogenic cyanide. If these substances are directly discharged into...
