Sewage regulating tank convenient for quality-divided and graded regulation

Abstract

The invention discloses a sewage regulating tank convenient for regulating according to quality and grade, which structurally comprises a regulating tank capable of regulating according to quality and grade, the regulating tank consists of at least two independent regulating sub-tanks which are connected in sequence, and the regulating sub-tanks are connected through a communicating pipeline provided with an automatic control gate valve; a digital flow meter is arranged on a water inlet pipe at the front end of the first adjusting sub-tank at the foremost end, and a water quality and liquid level monitoring device is arranged at the rear end in the first adjusting sub-tank; an electric stirrer is arranged in each adjusting sub-tank; a submersible sewage pump is arranged at the bottom in each adjusting branch tank, and each submersible sewage pump is connected with a water outlet main pipe through a water outlet branch pipe; and the digital flow meter, the water quality and liquid level monitoring device, each electric stirrer, the self-control gate valve and each submersible sewage pump are electrically connected with the control device. The sewage regulating tank can conveniently realize quality-based and graded regulation of sewage according to water quantity, water quality and liquid level height, reduces ineffective consumption of a front-end carbon source, and provides guarantee for a rear-end sewage treatment main body system.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a sewage conditioning tank for the front-end treatment of sewage, which is convenient for quality classification and grading adjustment. Background technique [0002] Whether it is urban sewage or industrial wastewater, the quality and quantity of water will fluctuate greatly over time, and the uneven influent flow and concentration will have an impact on the back-end sewage treatment system, making the sewage treatment system unable to maintain optimal It can even cause system paralysis. In order to improve the anti-shock load capacity of the sewage treatment system, the sewage adjustment tank of the front-end facilities of the sewage treatment system with large fluctuations in water quality and quantity is usually used to adjust the water quantity and quality of the incoming and outgoing water. In the actual sewage treatment system, especially in the village sewage treatment sy...

Problems solved by technology

[0004] However, the existing sewage adjustment tanks that can adjust a certain amount of water quality and quantity use micro-dynamics (such as: gravity flow or setting baffle overflow, etc.) to adjust, which has a limited effect on the balance of water quantity and quality, and cannot regulate water quality and quantity fluctuations. Larger incoming water to adjust
