The invention discloses a water circulation system based on near-zero emission of an electroplating industrial park, and relates to the technical field of electroplating sewage treatment. The problemof manual liquid level monitoring is solved. The system comprises a base, a second treatment box is arranged on the outer wall of the top of the base, a first treatment box is arranged on the outer wall of the top of the base, a water inlet pipe is arranged on the circumferential outer wall of the first treatment box, a first one-way valve is arranged on the circumferential outer wall of the waterinlet pipe, an L-shaped plate is arranged on the outer wall of the top of the first treatment box, a collision sensor is arranged on the outer wall of the bottom of the L-shaped plate, and the signaloutput end of the collision sensor is electrically connected with the control module. The collision sensor transmits a signal to the control module, and the control module is electrically connected with and controls the second water suction pump to be started, so that sludge-removed sewage is conveyed into the second treatment box through the second conveying pipe, liquid conveying operation is automatically completed, manual watching is avoided, manpower is saved, and the water treatment efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of electroplating sewage treatment, in particular to a water circulation system based on zero discharge in electroplating industrial parks. Background technique [0002] Electroplating industrial park wastewater mainly includes electroplating, chemical composite plating, and printed circuit board production wastewater. Electroplating wastewater treatment mainly includes six parts: dosing water, flushing water, acid-base oily wastewater, cyanide-containing wastewater and waste liquid, and sludge. Electroplating wastewater The water quality is complex and the composition is difficult to control. It contains heavy metal ions such as chromium, cadmium, nickel, copper, zinc, gold and silver, and cyanide. Some of them are highly toxic substances that are carcinogenic, teratogenic and mutagenic. To carry out zero discharge, therefore, we propose a water circulation system based on the electroplating industrial park...
