Problems solved by technology

At present, this method has not been reported for the treatment of electroplating wastewater in China. This process only needs a circulating spray system and a countercurrent rinsing system. Concentration in the rinsing tank, while using the spray device saves space compared to the rinsing tank, so its operating cost is definitely lower than the countercurrent rinsing method

Abstract

The invention relates to a treatment device for completely recycling electroplating rinse water. The treatment device comprises a spraying concentrating system device, a counter-current washing concentrating system and a plating slot, wherein the spraying concentrating system device comprises a first water pump, a spraying slot, a spray nozzle and a spraying recycling slot; the spraying slot communicates with the plating slot through a first pipeline; a three-way valve is mounted on the first pipeline; the spray nozzle is arranged in the spraying slot; the spraying recycling slot is formed below the spraying slot, and communicates with the bottom of the spraying slot through a second pipeline; the spraying recycling slot is further connected to the three-way valve through a third pipeline;and the first water pump is arranged on the third pipeline.

Description

technical field [0001] The invention relates to a processing device and method for zero discharge of rinsing water, and more specifically relates to a processing device and method for realizing full recovery and utilization of rinsing water in electroplating and rinsing by a circulating spray concentration method and zero discharge of rinsing water. Background technique [0002] Electroplating is one of the industrial industries with strong versatility and wide application. Almost all industrial sectors have a certain range of electroplating processing. However, electroplating industrial wastewater is extremely harmful to the environment. Different electroplating processes will produce different electroplating wastewater, mainly including wastewater generated before electroplating, waste liquid generated during the electroplating process of plated parts, and electroplating rinsing generated by cleaning the plated parts after plating. waste water. However, the methods of tre...
