Embodiment Construction

[0037] The technical solutions in the embodiments of the present invention are clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts belong to the protection scope of the present invention.

[0038] In the following description, a lot of specific details are set forth in order to fully understand the present invention, but the present invention can also be implemented in other ways different from those described here, and those skilled in the art can do it without departing from the meaning of the present invention. By analogy, the present invention is therefore not limited to the specific examples disclosed below.

[0039] Such as Figure 1 ~ Figure 4As s...

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...
