Problems solved by technology

However, the existing electroplating wastewater treatment system usually cannot effectively filter the sediment in the wastewater after the electroplating wastewater is added to the reaction, which will cause greater pressure on the subsequent wastewater treatment system, which is not conducive to the evolution of electroplating wastewater

Abstract

The invention relates to the field of environmental protection science and technology, and discloses an electroplating wastewater treatment system for a circuit board. The electroplating wastewater treatment system for the circuit board comprises a reaction tank, wherein a liquid feeding tube is arranged on the upper portion of the wall of the left side of the reaction tank; a slag discharging tube is arranged on the lower portion of the wall of the left side of the reaction tank; a stopping block of which the size is matched with that of a slot is arranged in a groove of the slag dischargingtube; an inserting opening is formed in the wall between the liquid feeding tube and the slag discharging tube; a rotating shaft is arranged in the inserting opening; the end, which is positioned on the outside of a tank body, of the rotating shaft is connected with a motor; an arc-shaped brush strip is arranged at the end, which is positioned on the inner side of the tank body, of the rotating shaft; and the arc-shaped brush strip sleeves the rotating shaft. A purpose of filtering electroplating wastewater can be achieved, the reacted electroplating wastewater is drained after being filtered,and the circumstance that a next wastewater treatment link has multiple impurities to affect a wastewater treatment progress is avoided.

Description

technical field [0001] The invention relates to the field of environmental protection technology, in particular to a circuit board electroplating wastewater treatment system. Background technique [0002] Electroplating wastewater is a kind of wastewater to be treated that contains highly toxic substances such as chromium, cadmium, nickel, copper, zinc, gold, silver and other heavy metal ions and cyanide, and some of these substances are highly carcinogenic, teratogenic, and mutagenic. The main source of toxic substances is the cleaning water and electroplating solution of the plated parts. When the electroplating wastewater is discharged into the river without treatment, the harmful substances in it will kill the organisms in the river or pass it to humans through the biological chain, which will have a great negative impact. [0003] The treatment of electroplating wastewater helps to reduce the pollutants in wastewater and reduce the harm of electroplating wastewater to ...
