Integrated simultaneous phosphorus and nitrogen removal system

Abstract

The invention discloses an integrated simultaneous phosphorus and nitrogen removal system. The system is concentrated in one container on the whole, the structural composition is tight, and the occupied space is small. A baffling communication mode is adopted, the flow of sewage in the system is prolonged, and a substrate in sewage makes fully mixed contact with microorganisms. In order to guarantee the effluent quality, the system is provided with a spare biological membrane reaction chamber, a water quality monitor is arranged in a clear water chamber and used for detecting indexes such as metal ions, pH values and microelements in water obtained after detection treatment, and once the detection indexes are not qualified, a controller can control sewage to enter the biological membrane reaction chamber to be treated from a biological contact oxidation chamber and then enter a clear water pool to be stored. Due to the fact that the biological membrane reaction chamber is selectively used, the use frequency is lowered, the maintenance period is long, and the maintenance cost is low.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an integrated synchronous nitrogen and phosphorus removal system. Background technique [0002] Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc., and it has also increasingly entered the daily life of ordinary people. According to the classification of sewage sources, sewage treatment is generally Divided into production sewage treatment and domestic sewage treatment. [0003] Domestic sewage is one of the important sources of water pollution in my country. Advanced treatment and reuse of domestic sewage can not only reduce potential secondary pollution, but also alleviate the current situation of water shortage in my country. Therefore, in order to meet the needs of social development, continuous improvements have been m...

AI Technical Summary

Problems solved by technology

The purchase and maintenance costs of the membrane bioreactor are high, and its setting greatly increases the cost of sewage treatment, and the effluent has no sedimentation and filtration measures after biological contact oxidation treatment, and the SS concentration of the effluent is high. Higher sludge concentration, lower nitrification efficiency, the first aeration zone of the equipment is not conducive to the cultivation of denitrifying phosphorus-accumulating bacteria, and the denitrification effect is not good when treating sewage with low carbon-to-nitrogen ratio
