Environment-friendly electroplating wastewater treatment equipment

Abstract

The invention discloses environment-friendly electroplating wastewater treatment equipment, which comprises a waste liquid treatment tank and a settling tank, wherein water inlet pipes are communicated with the two sides of the waste liquid treatment tank, the waste liquid treatment tank is communicated with the settling tank through a connecting pipe, a water outlet pipe is communicated with oneside of the settling tank, and a liquid medicine storage tank is fixedly mounted at the top of the waste liquid treatment tank; the top of the liquid medicine storage box communicates with a liquid outlet pipe, a valve is installed on the liquid outlet pipe, and the liquid outlet pipe communicates with the waste liquid treatment box through a plurality of flow dividing pipes. In the waste liquid treatment device, liquid medicine is fed into the waste liquid treatment box through the multiple flow dividing pipes and can evenly enter the waste liquid treatment box, so that the liquid medicine makes full and even contact with the surfaces of the spraying plates, and the spraying plates on the two sides swing around a rotating shaft in a reciprocating mode under the connection effect of a third connecting rod through reciprocating movement of a sliding rod in the vertical direction; therefore, the liquid medicine can be in full and uniform contact with the electroplating wastewater, and the wastewater treatment effect is improved.

Description

technical field [0001] The invention relates to the technical field of electroplating wastewater treatment equipment, in particular to an environment-friendly electroplating wastewater treatment equipment. Background technique [0002] The sources of electroplating wastewater are generally: (1) cleaning water for plating parts; (2) waste electroplating solution; (3) other wastewater, including: washing the floor of the workshop, washing water for plate washing, condensed water from ventilation equipment, and seepage due to plating tanks. Various tank fluids and drains of "running, popping, dripping, and leaking" caused by leakage or improper operation and management; (4) Equipment cooling water, which has not been polluted except for the temperature rise during use. [0003] The water quality and quantity of electroplating wastewater are related to factors such as the process conditions of electroplating production, production load, operation management, and water use method...

AI Technical Summary

Problems solved by technology

[0005] First of all, when treating wastewater, it is necessary to add medicine to the waste liquid treatment tank. In the prior art, there is a problem of uneven dosing, resulting in too much or insufficient medicine. Secondly, the chemical method uses chemical reagents and harmful metal particles in electroplating wastewater. The reaction forms a metal complex and precipitates to achieve the effect of removing harmful metal ions. Therefore, there will also be sediment on the inner wall of the chemical reaction tank. If it is not cleaned for a long time, the charge migration of harmful metal ions will not only corrode the inside of the chemical reaction tank. wall, and also reduces the internal volume of the chemical reaction cell
