Sewage treatment system with deodorization function and treatment method

Abstract

A sewage treatment system with a deodorization function comprises a two-level biochemical treatment system embedded underground, and the two-level biochemical treatment system is internally provided with a grid regulating tank, an anoxic tank, a first aerobiotic tank, a second aerobiotic tank, a settling tank and a middle water tank which are connected in sequence; a seepage-proof plate is arranged on the two-level biochemical treatment system, an artificial wetland is arranged on the seepage-proof plate, a water inlet pipe is arranged on the upper portion in the artificial wetland, and a water outlet pipe is arranged on the lower portion of the artificial wetland; a circulating pump is arranged in the middle water tank, and the water inlet pipe is connected with the circulating pump. An air collecting channel is formed between the two-level biochemical treatment system and the seepage-proof plate, and an air pipeline is arranged on the lower middle portion of the artificial wetland and provided with pores; the sewage treatment system further comprises an induced draft fan, an air inlet of the inducted draft fan is connected with the air collecting channel, and an air outlet is connected with the air pipeline. The sewage treatment system and method have multiple functions of two-level sewage biochemical treatment, advanced treatment and biological deodorization.

Description

technical field [0001] The invention relates to the field of water treatment, in particular to a sewage treatment system with a deodorizing function and a treatment method. Background technique [0002] At present, the domestic sewage and reclaimed water treatment technologies of traditional residential areas (including hotels, resorts, and schools) in the market generally have defects such as complex process flow, serious secondary pollution, especially odor pollution, and complicated management of treatment stations. According to a certain According to an incomplete survey of a coastal city, the successful operation rate of the small and medium-sized sewage treatment facilities that have been built is less than 20%. The main reason why the treatment facilities cannot be put into normal operation is that the treatment station lacks professional management personnel and the secondary pollution of the treatment station receives complaints from residents. too high.

Problems solved by technology

[0002] At present, the domestic sewage and reclaimed water treatment technologies of traditional residential areas (including hotels, resorts, and schools) in the market generally have defects such as complex process flow, serious secondary pollution, especially odor pollution, and complicated management of treatment stations. According to a certain According to an incomplete survey of a coastal city, the successful operation rate of the small and medium-sized sewage treatment facilities that have been built is less than 20%. The main reason why the treatment facilities cannot be put into normal operation is that the treatment station lacks professional management personnel and the secondary pollution of the treatment station receives complaints from residents. too high

However, the device occupies a large area and cannot effectively remove the odor generated during the sewage treatment process.
