Low-carbon and energy-conservation type settling and adjusting tank

Abstract

The invention discloses a low-carbon and energy-conservation type settling and adjusting tank which comprises a primary settling tank and an adjusting tank. The primary settling tank and the adjusting tank are arranged in parallel, the primary settling tank comprises a settling tank body and a water collecting tank, a water level measuring and controlling device is arranged in the water collecting tank, the settling tank body is connected with a water inlet, the water collecting tank is provided with a water outlet and an overflow opening, the water outlet is used for being connected with a biological processing system, the overflow opening is connected with the adjusting tank, a pipe bottom elevation of the overflow opening is the same as the pipe top elevation of the water outlet, a lifting pump is arranged in the adjusting tank, and the water level measuring and controlling device is connected with the lifting pump. The low-carbon and energy-conservation type precipitating and adjusting tank disclosed by the invention is suitable for pretreatment of small and micro sewage treatment facilities of independent industrial and mining enterprises, expressway service stations and the like; as the primary settling tank and the adjusting tank are jointly constructed, the settling and adjusting tank has a simple structure and easiness in water level control; sewage can exceed the adjusting tank according to the average flow to directly enter a subsequent biochemical treatment system, and a part exceeding the average flow is dammed to the adjusting tank; thus, the water volume for the adjusting tank to lift is reduced, and operation energy consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a low-carbon and energy-saving sedimentation regulating tank which organically combines a primary sedimentation tank and a regulating tank. Background technique [0002] In order to strengthen ecological environment construction, protect water ecological environment and drinking water resources, in recent years, my country has stepped up environmental protection efforts, and built new campuses, distributed communities, townships, villages, etc. in independent factories and mines, expressway service stations, colleges and universities Vigorously promote the construction of small and micro sewage treatment facilities, and require nitrogen and phosphorus removal treatment of sewage to prevent eutrophication components (nitrogen, phosphorus) from entering rivers, rivers, lakes (reservoirs), and sea surface water bodies. [0003] In order to realize the denitrification and pho...

AI Technical Summary

Problems solved by technology

[0004] In addition, in order to maintain the normal and continuous operation of small and micro sewage treatment facilities such as independent factories and mines, expressway service stations, newly-built campuses of colleges and universities, decentralized communities, and towns and villages, it is necessary to increase the measures such as regulating pools and their pumps. Resulting in large equipment investment and operating costs, and increased management difficulty
