A double-tube multi-grid self-stirring combined purification tank

Abstract

The invention discloses a double-cylinder multi-cell self-stirring combined purifying tank. The double-cylinder multi-cell self-stirring combined purifying tank comprises an outer cylinder and an inner cylinder; four separating plates arranged on the outer wall of the inner cylinder are used for separating a cavity into a second cell, a third cell, a fourth cell, and a fifth cell; the inner cylinder is taken as a first cell; an inclined separating plate is arranged in the inner cylinder; a liquid sealing cavity is formed by the inclined separating plate and the part of the inner cylinder below the inclined separating plate; the inclined separating plate is provided with a guide pipe, and a gas inlet; the part of the inner cylinder below the second cell is fixedly provided with a U-shaped pipe; an opening on one end of the U-shaped pipe is arranged to be above the liquid sealing cavity, and an opening on the other end of the U-shaped pipe is arranged to be above a second separating plate. According to the double-cylinder multi-cell self-stirring combined purifying tank, the interior of the double-cylinder multi-cell self-stirring combined purifying tank is divided into five different functional zones; waste water high efficiency purification is realized; occupied space is small; buried installation is realized; the double-cylinder multi-cell self-stirring combined purifying tank can also be place on seepage wells and provided with well covers; maintenance is convenient to realize; stirring mixing of microorganisms with waste water can be realized using the double-cylinder multi-cell self-stirring combined purifying tank without mechanical assistant effect; energy consumption is reduced; the double-cylinder multi-cell self-stirring combined purifying tank is economical; the interior of the double-cylinder multi-cell self-stirring combined purifying tank is detachable; and maintenance is convenient.

Description

technical field [0001] The present invention relates to a purification tank, and more specifically, to a dual-cylinder multi-grid self-stirring combined purification tank which utilizes the gas fed by an air pump to realize self-stirring to increase the effect and efficiency of sewage purification. Background technique [0002] Most of the domestic sewage in rural areas in my country is distributed, and it is discharged randomly without any treatment, which is the main reason for the deterioration of the overall water quality of rivers. The nutrients mainly nitrogen and phosphorus exceed the standard seriously. The water purification tanks that have been developed have problems such as poor anti-buffering capacity, low pollutant removal rate, inconvenient production and processing, and difficult maintenance, which are far from meeting the needs of purifying scattered rural sewage. It is imminent to develop a sewage purification device that has the advantages of high removal ...
