Abstract
The invention discloses a fast treatment device for zinc-containing electroplating wastewater. The fast treatment device comprises a neutralizing tank, a pump and PLC (programmable logic controller), wherein a hollow shaft type speed reducer is arranged on the neutralizing tank, and a hollow stirring shaft is mounted on the hollow shaft type speed reducer, and communicated with a first liquid inlet pipe through a rotating joint arranged at the top of the hollow stirring shaft; an activated carbon filter plate is horizontally arranged at the bottom of the neutralizing tank; a PH ((Potential Of Hydrogen) sensor is fixed on the side wall of the neutralizing tank, and connected with the PLC through wires, and the PLC is further connected with a first electromagnetic valve, a second electromagnetic valve and a pump. According to the fast treatment device provided by the invention, wastewater is dispersed in the neutralizing tank from liquid distributing holes, so that the dispersion efficiency is high; the PH value of a mixed solution is adjusted through the PLC to ensure that the PH value of a neutralization liquid meets standards; the activated carbon filter plate filters and removes precipitates generated by neutralization. The fast treatment device of zinc-containing electroplating wastewater disclosed by the invention is simple and reasonable in overall structure, high in neutralization efficiency, good in filtering effect, low in labor intensity, high in automation degree and is manpower-saving.
Description
technical field [0001] The invention relates to an electroplating water treatment device, in particular to a rapid treatment device for zinc-containing electroplating wastewater. Background technique [0002] The sources of electroplating wastewater are generally: (1) plating cleaning water; (2) waste electroplating solution; (3) other wastewater, including washing the floor of the workshop, scrubbing plate washing water, condensed water from ventilation equipment, and leakage from plating tanks. Or various tank liquids and drainages of "running, popping, dripping, and leaking" caused by improper operation and management; (4) Equipment cooling water, which has not been polluted except for the temperature rise during use. The water quality and quantity of electroplating wastewater are related to the process conditions of electroplating production, production load, operation management and water use methods and other factors. The water quality of electroplating wastewater...
