Multistage precipitating device for industrial sewage treatment

Abstract

The invention discloses a multi-stage sedimentation device for industrial sewage treatment, which comprises an outer cylinder, an inner cylinder, a water inlet pipe, a sand collection bucket, a support leg, a discharge valve I, a short connection, a ring pipe, and a water outlet pipe. The inner cylinder A water inlet pipe is provided on one side of the upper part, and the water inlet pipe is connected tangentially to the inner cylinder; The outer cylinder is through-connected; the short connection is connected through a ring pipe, the short connection side is provided with an outlet pipe, and the lower side of the outer cylinder is provided with a sand collection bucket, the sand collection bucket is funnel-shaped, and the sand collection bucket A number of legs are provided on one side of the exterior, and a discharge valve I is provided on the lower side of the sand collecting bucket. The water inlet pipe of the present invention is connected tangentially to the inner cylinder, and the inner cylinder first performs swirling to remove sand to remove most of the sediment, and then settles in the outer cylinder, thereby enhancing the effect of sewage sedimentation and improving the efficiency of sewage sedimentation.

Description

Technical field [0001] The invention belongs to the technical field of environmental protection equipment, and particularly relates to a multi-stage precipitation device for industrial sewage treatment. Background technique [0002] For a long time, industrial wastewater has been one of the problems that restrict the rapid development of industry, and how to treat industrial wastewater is also a problem that everyone is concerned about; therefore, how to scientifically and rationally treat industrial wastewater has always been the subject of efforts by domestic and foreign experts; precipitation It is one of the commonly used processes in sewage treatment. It uses the natural precipitation or coagulation precipitation of water to remove suspended solids in the water. The traditional precipitation device covers a large area and can only use the passage of time when performing the precipitation operation. It slowly settles naturally, it takes a long time to complete the precipitati...

Problems solved by technology

[0002] For a long time, industrial sewage has been one of the problems restricting the rapid development of industry, and how to deal with industrial sewage is also an issue of concern to everyone; therefore, how to treat industrial sewage scientifically and rationally has always been a subject of hard work by experts at home and abroad; precipitation It is one of the commonly used processes for sewage treatment. It uses the natural sedimentation or coagulation of water to remove suspended solids in water. Traditional sedimentation devices occupy a large area and can only use the passage of time when performing sedimentation operations. Slowly and naturally precipitate, it takes a long time to complete the precipitation, and the efficiency is low
