Embodiment Construction
[0042] The implementation of the present application will be described in detail below with reference to the accompanying drawings and examples, so as to fully understand and implement the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects.
[0043] see Figure 1-Figure 16 As shown, the present invention provides a zero-discharge treatment device for electroplating sewage, including a plate and frame filter press, and the plate and frame filter press includes:
[0044] A filter plate 1 is arranged in a row between the two beams 12 of the plate and frame filter press. Both ends of the filter plate 1 are provided with support parts 101. Each filter plate 1 has a filtering state and an idle state. When the two adjacent filter plates 1 are in contact, in the idle state, the two adjacent filter plates 1 are separated;
[0045] The slider 2 is slidably arranged on the crossbeam 12 in one-to-one correspo...

The invention belongs to the technical field of environmental protection, and specifically relates to a zero-discharge treatment device for electroplating sewage, which includes a filter plate, a sliding part, a turning transmission part and a power shaft. When the filter plate is switched from a filtering state to an idle state, the sliding part will carry The first transmission part moves to the overturning area. At this time, the first transmission part is in transmission connection with the second transmission part, and when the clamping part rotates, it will drive the filter plate from the filter press through the rotation of the support shaft. Flip over to its outside. The plate and frame filter press in the electroplating sewage zero-discharge treatment device of the present invention is extremely convenient to replace the filter cloth; the present invention also provides a zero-discharge treatment method for electroplating sewage, using the above-mentioned zero-discharge treatment device for electroplating sewage, the present invention The zero-discharge treatment method of electroplating sewage greatly improves the efficiency of sewage treatment by simplifying the filter cloth maintenance work of the plate and frame filter press during sewage treatment.
Description
technical field [0001] The invention belongs to the technical field of environmental protection, and specifically relates to a zero-discharge treatment device and method for electroplating sewage. Background technique [0002] Electroplating is an indispensable technology in the surface treatment industry and an irreplaceable industry for mechanical products. Electroplating wastewater mainly includes electroplating, chemical composite plating and printed circuit board production wastewater. Electroplating wastewater treatment mainly includes six parts: dosing water, rinsing (washing) water, acid-base oily wastewater, cyanide-containing wastewater and waste liquid, and sludge. Depending on the industry and the type of plating of the enterprise, the processing content is different. [0003] With the continuous development of electroplating sewage treatment, the zero discharge treatment technology of electroplating sewage has become mature, especially after adding reverse osm...
