Abstract

The invention discloses a SBBR sewage treatment device for side flow dephosphorization and a method thereof, the device comprises an SBBR, the SBBR is respectively connected with an adjusting tank and a sludge tank through pipelines, a supernatant reflux pump is also arranged between the sludge tank and the adjusting tank, the SBBR is respectively connected with an aeration fan I and an aeration fan II through aeration pipes, A first water outlet pneumatic valve and a second water outlet pneumatic valve are arranged on the SBBR reactor, a liquid level sensor, a dissolved oxygen sensor and a temperature sensor are further arranged in the SBBR reactor, the SBBR reactor and the sludge tank are further connected with a coagulant adding device, and the SBBR reactor is connected with a carbon source adding device. The invention also comprises a method for treating sewage by adopting the device. According to the system, the dephosphorization efficiency can be improved, various operation parameters are accurately controlled by the PLC through the feedback of the online temperature and the Do value, the operation energy consumption can be effectively reduced, and the impact load resistance of the system is improved.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a SBBR sewage treatment device and method for side-flow dephosphorization. Background technique [0002] With the development of my country's ecological civilization construction, the governance of the water environment has been pushed to a new level. Under the increasingly stringent environmental protection requirements, the water quality of sewage treatment has reached the first level of the "Pollutant Discharge Standards for Urban Sewage Treatment Plants" (2002) A discharge standard has gradually become the minimum discharge requirement. BOD5, SS and other indicators other than nitrogen and phosphorus in sewage can be effectively removed under general process treatment, but the effective removal of nitrogen and phosphorus that cause eutrophication of water bodies is often the key to each Difficulties of sewage treatment enterprises. The emission standards f...
