Treatment equipment for industrial acidic sewage

Abstract

The invention belongs to the field of sewage treatment equipment, and particularly relates to treatment equipment for industrial acidic sewage, the treatment equipment comprises a filter box and a neutralization box, the filter box is arranged above the neutralization box, the bottom of the filter box is communicated with the interior of the neutralization box, a filter mechanism is arranged in the filter box, and the neutralization box is communicated with the bottom of the filter box. A feeding box is arranged above the neutralization box, an alkaline neutralizer is contained in the feeding box, and a stirring mechanism and a feeding mechanism are arranged in the neutralization box; the filtering mechanism comprises a material receiving groove fixedly connected to the inner wall of the filtering box, a discharging opening communicated with the material receiving groove is formed in the side wall of the filtering box, and the two sides of the material receiving groove are fixedly connected with obliquely-arranged filtering net plates. Solid impurities in acidic sewage can be filtered out and automatically cleaned and discharged, frequent manual cleaning or filter screen plate replacement is not needed, the labor intensity is reduced, an alkaline neutralizer can be crushed and ground through the crushing balls, and contact dissolution of the alkaline neutralizer and the acidic sewage is facilitated.

Description

technical field [0001] The invention belongs to the field of sewage treatment equipment, in particular to a treatment equipment for industrial acid sewage. Background technique [0002] In industrial production, high-concentration wastewater with acid content greater than 3%-5% is called acid wastewater, and neutralization treatment is often used to make its pH value meet the standard of wastewater discharge. The neutralization treatment method is to add acid wastewater Adding alkaline substances, such as lime, sodium hydroxide and limestone, etc., can be used for products treated with strong acid to make the wastewater neutral. [0003] The existing industrial acid sewage treatment equipment has the following problems in use: there are a large number of solid impurities in the acid sewage, which needs to be filtered before neutralization treatment, and a large amount of impurities accumulated on the surface of the filter screen plate after a long time of filtration can easi...

AI Technical Summary

Problems solved by technology

[0003] The existing industrial acid sewage treatment equipment has the following problems in use: there are a large amount of solid impurities in the acid sewage, which need to be filtered before neutralization treatment, and a large amount of impurities are accumulated on the surface of the filter plate after long-term filtration, which is easy to cause blockage. Frequent manual cleaning or direct replacement of the filter plate is required, which is time-consuming and laborious, which is not conducive to the improvement of work efficiency; alkaline substances are in the form of blocks and large particles, which are not easy to react quickly with the acid in the wastewater, reducing the efficiency of neutralization treatment, and alkaline After the material is put in, the acid-base neutralization reaction will generate high temperature, which will easily make the wastewater heat up and evaporate, which is not conducive to work stability
