Wastewater treatment device used in chemical industry

Abstract

The invention discloses a wastewater treatment device used in chemical industry, and relates to the technical field of wastewater treatment. The wastewater treatment device comprises a filter box, wherein a water inlet pipe is arranged on the upper surface of the filter box, a first grid plate and a second grid are arranged in the filter box, and an activated carbon adsorption layer, a microporousfilter plate and a first filter screen are arranged in the filter box. According to the wastewater treatment device used in the chemical industry, a stirring rod, a second filter screen, a guide plate, a box body, a motor and a sealing cover are mutually matched, so that the motor drives the stirring rod to rotate so as to stir wastewater, furthermore, reagents are added in the box body, and therefore, the neutralization reaction between chemical ions and the reagents in wastewater can be accelerated to ensure the reaction efficiency between the chemical ions and the reagents, and in addition, the second filter screen can filter precipitates after the neutralization reaction for one time to be convenient for a worker to take out the precipitates from the upper part, thereby being capableof ensuring the effect of wastewater treatment, and to be further convenient for the worker to treat the precipitates in the treatment device.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a chemical sewage treatment device. Background technique [0002] Sewage treatment: the process of purifying sewage to meet the water quality requirements for discharge into a certain water body or for reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc., and it is also increasingly entering the daily life of ordinary people. [0003] In the process of chemical sewage treatment, it is often necessary to add chemicals to neutralize chemical ions, but the mixing effect of sewage and chemicals in the existing treatment process is not ideal, resulting in low treatment efficiency of chemical ions. At the same time, the neutralized chemical Ions may produce precipitation, which needs to be cleaned after long-term use, but t...
