Hydrocyclone precipitator and sewage treatment equipment

Abstract

The invention discloses a hydrocyclone precipitator. The hydrocyclone precipitator comprises a center pipe, a sludge hopper, a water inflow branch pipe, a water inflow flow guiding plate and a water outflow groove. The center pipe is fixedly arranged on the upper portion in a precipitator body, the sludge hopper is located below the center pipe in the precipitator body, the water inflow flow guiding plate is arranged on a water inlet in the lower portion of the center pipe in the tangential direction of the center pipe, the water outflow end of the water inflow branch pipe for water inflow is adjacent to the water inflow flow guiding plate, and the water outflow groove is communicated with the top of the center pipe. The bottom end of the sludge hopper is connected with a sludge discharge pipe. According to the hydrocyclone precipitator, through the secondary separation treatment technology, the surface hydraulic load is high, and the hydrocyclone precipitator can be suitable for high turbidity high sewage treatment with the high inflow water suspended solid content, and has the capacity of resisting sewage amount and water quality change impacts. The invention further provides sewage treatment equipment. The sewage treatment effect is good, the blocking phenomenon is not likely to be generated, and the structure is compact.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a hydrocyclone precipitator and sewage treatment equipment. Background technique [0002] A large amount of sewage is produced in the production process of petroleum, chemical industry, medicine, metallurgy, mining and other industries, especially the acidification and precipitation treatment of PTA sewage. It is difficult for the existing equipment to meet the requirements of water quality treatment. The separation is not complete, and the treatment effect of mud-water separation is poor. The sewage treatment effect is closely related to human daily life. How to improve the sewage treatment efficiency has become an urgent problem to be solved. Contents of the invention [0003] The purpose of the present invention is to provide a hydrocyclone precipitator to solve the above-mentioned problems in the prior art. The hydrocyclone precipitator adopts secondary separation ...
