Embodiment 1

[0037] This embodiment provides a sewage treatment system to treat a rural sewage treatment project in a town in Shantou. The sewage treatment capacity of this project is 500t / day, and the main indicators of sewage are: COD 80-200mg / L, total nitrogen 35-40mg / L, total Phosphorus 6~8mg / L.

[0038] like figure 1 As shown, the sewage treatment system of this embodiment includes anoxic biochemical zone 2, aerobic biochemical zone 13 and control zone 26, as well as oxygen supply group, water production module, control system 27 and sensor system, wherein the anoxic biochemical zone 2 is provided with a grid device 3 at the position of the water inlet 1, and the grid device 3 can also be set as an automatic grid machine or a grid network according to the actual situation. The purpose of the grid device 3 is to Intercept the floating matter, hair and other sundries in the sewage to pre-filter the sewage. Due to the non-homogeneous discharge property of sewage, firstly, the anoxic bi...

Abstract

The invention discloses a sewage treatment system and a sewage treatment method, and belongs to the field of sewage treatment, wherein the sewage treatment system comprises an anoxic biochemical region, an aerobic biochemical region, a control region, an oxygen supply air-stripping unit, a water production module, a control system and a sensing system; the oxygen supply air-stripping unit comprises a fan, an air distribution device and an air stripping device; the air stripping device comprises an air stripping pipe, a lifting pipe, and an air stripping electric valve arranged on the air stripping pipe; the air distribution device is arranged at bottoms of the anoxic biochemical region and the aerobic biochemical region; the lifting pipe is arranged in the anoxic biochemical region; the air stripping pipe is arranged at the bottom of the anoxic biochemical region; the air stripping pipe is connected with a negative pressure water inlet in one end of the lifting pipe; the fan supplies air to both the air distribution device and the air stripping device. The sewage treatment system provided by the invention has advantages of simple structure, low energy consumption, energy conservation and environment friendliness.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a sewage treatment system and a treatment method thereof. Background technique [0002] In the field of sewage treatment, the domestic sewage treatment technology is mainly anaerobic-anoxic-aerobic traditional activated sludge method, which usually has a long residence time, large tank volume, low intelligence, high solid waste output, and easy treatment. The effect is unstable and other limitations. Most of the small and medium-sized domestic sewage in urban and rural areas is directly discharged without treatment. To establish a sewage treatment plant in the area requires a lot of land, a lot of money, cumbersome pipe network laying, and a long construction period. The effect can only be seen in the production area and the production area. [0003] In order to adapt to the treatment of small and medium-sized domestic sewage in urban and rural areas, water tanks are generally u...
