Industrial wastewater purification equipment

Abstract

The invention discloses industrial wastewater purification equipment, which comprises a bottom plate. Supporting legs are fixedly connected to the top surface of the bottom plate, and a collecting device is arranged at the top ends of the supporting legs. Through cooperation of the driving device and the stirring device, the industrial wastewater purification equipment can completely and uniformly mix a precipitator, a flocculant and industrial wastewater, the purification effect can be improved, meanwhile, the stirring device can scrape sludge adhered to the inner wall of the driving device, manual cleaning is not needed, the workload of workers is reduced, sewage is continuously treated through cooperation of the collecting device, the traction device, the reset device, the limiting device, the dehydration device and the slag scraping device, manual control is not needed, filter cakes can be automatically removed, the workload of workers is further reduced, operation is easy and convenient, the sewage purification efficiency can be improved, time and labor are saved, and the practicability of the industrial wastewater purification equipment is improved.

Description

technical field [0001] The invention relates to the field of industrial wastewater purification equipment, more specifically, to an industrial wastewater purification equipment. Background technique [0002] Industrial wastewater purification refers to the water used in the industrial production process is properly treated and reused for production or properly discharged from the factory, including the management of production water and the measures taken to facilitate the treatment of wastewater. Industrial wastewater treatment is mainly to remove chemical needs Oxygen, suspended matter, sulfide, petroleum, cyanide, hexavalent chromium, lead, cadmium, mercury, etc. There are three disposal methods for industrial wastewater. The first is to reuse without treatment or only after necessary treatment. Sometimes it is reused in the process to form a circulating water system, and sometimes it is used in other processes to form a sequential water system. The second is to do necess...

Problems solved by technology

[0003] When the existing mercury-containing industrial wastewater purification equipment is in use, the industrial wastewater is first filtered with a filter grid to remove suspended matter, then the pH of the wastewater is adjusted, and then the precipitant and flocculation agent are added to the wastewater using a dosing device. After that, the mercury in the industrial wastewater reacts with the precipitant and flocculant to form solid matter, and then it is allowed to stand for stratification, so that the solid matter gradually settles down to form sludge, and then the supernatant is passed into the adsorption tower, and the supernatant is treated For further purification, when there is a lot of sludge, the sludge is pumped out and put into the plate filter press, and then the plate filter press dehydrates the sludge. However, the mixing equipment in the mercury-containing industrial wastewater purification equipment cannot The precipitant, flocculant, and industrial wastewater are completely mixed evenly, resulting in poor purification effect, and the sludge generated during the purification process will adhere to the inner wall of the mixing equipment, resulting in incomplete sludge sedimentation, which requires manual cleaning and a large workload At the same time, the amount of sludge needs to be monitored manually and the sludge must be artificially driven into the plate filter press and the filter cake needs to be unloaded manually. The workload of the workers is large, and the purification work cannot be carried out continuously. The operation is time-consuming and laborious. Therefore, it is urgent Need to design an industrial wastewater purification equipment
