Industrial acidic wastewater treatment device

Abstract

The invention discloses an industrial acidic wastewater treatment device. The device comprises a shell, a plurality of supporting legs are evenly and fixedly connected to the bottom of the shell, an exhaust port is formed in the top of the shell, liquid inlet pipes are fixedly connected to the upper left corner and the upper right corner of the shell, a plurality of first through holes are evenlyformed in a baffle, and second through holes are formed in the positions, corresponding to the first through holes of the baffle, of a rotary drum. According to the industrial acidic wastewater treatment device, the transpiration device and a neutralization chamber are combined into a whole, the occupied area is greatly reduced and a cost is reduced, the baffle plate, the rotary drum, the first through holes and the second through holes are matched so that on-off control over a partition layer is achieved, through cooperation of an electric heating rod, a connecting base, a conducting ring anda power line, so that concentration of acid wastewater in the transpiration chamber is achieved, through cooperation of a main shaft and a stirring rod, neutralization treatment in the neutralizationchamber is accelerated, and through cooperation of a second motor, a fourth gear and a fifth gear, power supply of the stirring mechanism is achieved.

Description

technical field [0001] The invention relates to the technical field of industrial acid wastewater treatment, in particular to a treatment device for industrial acid wastewater. Background technique [0002] Industrial wastewater includes production wastewater, production sewage and cooling water. It refers to wastewater and waste liquid produced in the process of industrial production, which contains industrial production materials, intermediate products, by-products and pollutants produced in the production process lost with water. There are many types of industrial wastewater with complex components. For example, mercury is contained in electrosalt industrial wastewater, heavy metal smelting industrial wastewater contains various metals such as lead and cadmium, electroplating industrial wastewater contains various heavy metals such as cyanide and chromium, petroleum refining industrial wastewater contains phenol, pesticide manufacturing industrial wastewater Contains var...
