A self-stirring sewage treatment purification tank

Abstract

The invention relates to a novel self-stirring sewage treatment purification tank which comprises four cells arranged in a matts shape, an air pump, an air-blowing pipe and an aeration pipe. The novel self-stirring sewage treatment purification tank is characterized in that the upper portion of a first cell is provided with a buffer tank, a water inlet tank and an oil isolation tank. An oil separating plate is arranged in the buffer tank. A U-shaped pipe is arranged between the first cell and the second cell, the air-blowing pipe extends into the first cell so as to stir substrates in the first cell and the second cell; the aeration pipe extends into the third cell, so as to perform aerobic reaction of the third cell; and mud discharging pipes are disposed in the third cell and the fourth cell. The sewage treatment purification tank is integrally of a matts-shaped layout, the occupied space is small, the novel self-stirring sewage treatment purification tank can be connected to a sewage treatment pipe network, the oil separating plate can hold back oil stains, automatic stirring of the substrates can be achieved, the mud discharging pipes can discharge sludge in the purification tank in a steam stripping mode, sewage undergoes the anaerobic-anoxic-aerobic-precipitating process, and the purification treatment of the sewage is performed.

Description

technical field [0001] The invention relates to a sewage treatment purification tank, more specifically, a novel self-stirring sewage treatment purification tank. Background technique [0002] In terms of sewage treatment, there is a lack of a suitable method, which has a simple structure, and can meet the sewage treatment equipment installed directly in the sewage pipe network system, and at the same time achieve the effect of nitrogen and phosphorus removal. The problem that needs to be solved urgently is: there is no pollutant treatment system that can anaerobically treat high-concentration organic waste, and is suitable for removing pollutants such as nitrogen and phosphorus in low-concentration sewage, so that the scope of use of treatment facilities is limited In a certain range, the applicable surface is narrow. [0003] The invention uses an air pump to complete the process of sewage from anaerobic-anoxic-aerobic-sedimentation, including the mud discharge process, w...
