4 Reduced disposal methods

4.1 General rules 4.1.1 Electroplating enterprises should implement the classified collection of various electroplating wastewater to reduce the production of electroplating sludge with complex heavy metals. 4.1.2 The electroplating sludge reduction treatment enterprise shall classify and register the source and basic information of the electroplating sludge entering the plant, and determine it as a qualitative sludge Or mixed sludge. 4.1.3 Before electroplating sludge reduction treatment, this batch of sludge should be analyzed to determine pH, fluorine content, sulfur content, chlorine content, and metal elements For indicators such as content, moisture content, etc., the reduction and disposal methods are determined based on the analysis results. 4.2 Electroplating wastewater treatment process 4.2.1 RF microwave enhanced flocculation process 4.2.1.1 Method summary Use the strong electromagnetic action of the high-energy electric field to activate the polar molecules of the flocculant to improve the reaction efficiency, and combine with the conventional flocculation reaction. Into an enhanced process. 4.2.1.2 Process flow After the electroplating wastewater to be treated is adjusted to the appropriate pH by the preliminary acid and alkali in the primary adjustment tank, the appropriate agent is added, and it is transported through the inlet pump. It is sent to the radio frequency activation device and enters the flocculation sedimentation system after a certain period of time. The process flow of RF microwave enhanced flocculation is shown in Figure 1. ......
