Multi-stage precipitation device for treating industrial sewage

Abstract

The invention discloses a multi-stage precipitation device for treating industrial sewage. A water inlet pipe is arranged on one side of an upper barrel, a middle barrel is arranged on one side of thelower part of the upper barrel, a lower barrel is arranged on one side of the lower part of the middle barrel, inner barrels are correspondingly arranged on one sides of the inner parts of the upperbarrel, the middle barrel and the lower barrel, overflow grooves are formed in one sides of the upper parts of the inner barrels, and division plates are arranged on one sides of the lower parts of the inner barrels; siphons are arranged on one sides of the inner parts of the inner barrels, one ends of the siphons are higher than the bottoms of the inner barrels, the other ends of the siphons penetrate through the division plates, and the lower ends of the siphons in the lower barrels are connected with the water outlet pipe; a plurality of short circuits evenly distributed are arranged on onesides of the division plates, one ends of the short circuits communicate through ring pipes, the adjacent ring pipes are connected through a plurality of communicating pipes, a plurality sewage discharging pipes are arranged at the lower ends, on one sides of the lower pipes, of the ring pipes, and the sewage discharging pipes are provided with sewage discharging valves; and a plurality of support legs are arranged on one sides of the lower parts of the lower barrels. According to the multi-stage precipitation device for treating industrial sewage, vertical-type sewage multi-stage precipitation is adopted for multi-stage precipitation treatment of sewage, the floor area of the device is decreased, the using ratio of soil is increased, and the cost input of sewage treatment enterprises.

Description

technical field [0001] The invention belongs to the technical field of environmental protection equipment, in particular to a multi-stage sedimentation device for treating industrial wastewater. Background technique [0002] Industrial wastewater refers to wastewater, sewage and waste liquid produced in the process of industrial production, which contains industrial production materials, intermediate products and products lost with water, and pollutants generated in the production process; with the rapid development of industry, the waste water The types and quantities are increasing rapidly, and the pollution of water bodies is becoming more and more extensive and serious, threatening human health and safety; therefore, for the protection of the environment, the treatment of industrial wastewater is more important than the treatment of urban sewage; the traditional industrial wastewater treatment The method is to perform three-stage or four-stage filtration treatment on the...

[0002] Industrial wastewater refers to wastewater, sewage and waste liquid produced in the process of industrial production, which contains industrial production materials, intermediate products and products lost with water, and pollutants generated in the production process; with the rapid development of industry, the waste water The types and quantities are increasing rapidly, and the pollution of water bodies is becoming more and more extensive and serious, threatening human health and safety; therefore, for the protection of the environment, the treatment of industrial wastewater is more important than the treatment of urban sewage; the traditional industrial wastewater treatment The method is to perform three-stage or four-stage filtration treatment on the wastewater according to the different water quality. The sewage treatment equipment occupies a large area and the land utilization rate is low, which increases the cost input of the sewage treatment enterprise.
