Problems solved by technology

However, for rural retail sewage, there are problems such as too small water volume (mostly less than 10 tons per day), large fluctuations in water volume, and weak residents' operating ability. Suitable for small sewage pumps that run for a long time without maintenance. If you choose the above-mentioned traditional AAO or CASS sewage treatment process, the treatment facility will be out of service due to maintenance difficulties

Abstract

The invention discloses an air pump driven sewage reactor based on program control, and a treatment method thereof. The air pump driven sewage reactor comprises a water inlet tube, a sewage treatmentreactor, a PLC control cabinet and a water outlet tube, wherein an air pump and a PLC are arranged in the PLC control cabinet; the air pump is divided into a first air lifting tube, a second air lifting tube, a third air lifting tube and an aeration tube from the PLC control cabinet, and each air pipeline is opened by a PLC controlled solenoid valve; the sewage treatment reactor comprises an innercylinder and an outer cylinder, the inner cylinder is provided with a outlet water disinfecting zone, and the outer cylinder is divided into a water inlet zone and a main reaction zone by a partitionplate; a high liquid level gauge, a low liquid level gauge and the first air lifting tube are arranged in the water inlet zone; a bio-filler, the second air lifting tube and the aeration tube are arranged in the main reaction zone; a disinfecting tablet basket and the third air lifting tube are arranged in the outlet water disinfecting zone; and the water inlet tube is connected with effluent water from a septic tank, and is connected with the water inlet zone. The technical requirement of near zero maintenance of a small volume of sewage is met in the invention.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and relates to a sewage treatment device and a treatment method for a single household and adjacent multi-household villages with a small amount of water, in particular to an air pump-driven one-gas multi-purpose sewage treatment device and a treatment method. Background technique [0002] With the rapid development of my country's economy, the income of rural residents has increased significantly, and people have put forward higher requirements for the living environment. The problem of rural surface and groundwater pollution caused by scattered sewage has attracted much attention. It is urgent to collect and clean rural sewage. deal with. [0003] At present, in the treatment of urban domestic sewage in my country, the traditional anaerobic-anoxic-aerobic (commonly known as AAO) process and circulating activated sludge (commonly known as CASS) process are mostly used to remove organic m...
