Problems solved by technology

At present, there is no specific discharge standard for rural sewage treatment. Except for the local "Rural Sewage Discharge Standards" issued by individual provinces, the "Pollutant Discharge Standards for Urban Sewage Treatment Plants" (GB18918-2002) is generally adopted Level A or Level 1 B standard, in the face of strict discharge standards, most of the rural sewage treatment process equipm

Example Embodiment

[0042] Example 1: Integrated small and medium-sized multi-point water inlet deep denitrification and dephosphorization sewage treatment system, see Figure 1-Figure 3 , Including successively connected grid regulating tank 1, aeration tank 3, first anoxic tank 4, first aerobic tank 5, second anoxic tank 6, second aerobic tank 7, sedimentation tank 8, flocculation reaction Pool 9 and flocculation sedimentation tank 10.

[0043] A lift pump 2 is provided in the grid adjustment tank 1, and the lift pump 2 is connected to the aeration tank 3 and the first anoxic tank 4 through pipes; in the aeration tank 3, the first aerobic tank 5 and the second good The oxygen tank 7 is respectively provided with an aeration mechanism 12, the aeration mechanism 12 includes an aeration main pipe 23 corresponding to the external blower 11, and an aeration branch pipe 24 arranged at the bottom of the aeration tank 3 and communicated with the aeration main pipe 23, A microporous aerator 25 is evenly a...

Example Embodiment

[0049] Embodiment 2: An integrated small and medium-sized multi-point influent deep denitrification and phosphorus removal sewage treatment method, characterized in that the integrated medium and small multi-point influent deep denitrification and phosphorus removal sewage treatment system in Example 1 is used to perform Sewage treatment includes the following steps:

[0050] ① Introduce the sewage to be treated into the grid regulating tank;

[0051] ②The effluent water of the grille regulating tank is divided into two ways, the sewage that accounts for 50-80% of its total effluent enters the aeration tank as the first way; the sewage that accounts for 20-50% of its total effluent enters the first way as the second way Anoxic tanks provide carbon source for preliminary denitrification and denitrification;

[0052] ③ The sewage after denitrification in the first anoxic tank enters the first aerobic tank for aeration treatment to further remove COD and ammonia nitrogen;

[0053] ④The ...

Abstract

The invention discloses an integrated small and medium multi-point water inflowing deep nitrogen and phosphorus removal sewage processing system and a processing method. The system and method are mainly used for processing high-concentration town sanitary sewage and high-concentration industrial waste water, especially COD, sanitary sewage with high ammonia nitrogen content or industrial waste water. The processing system comprises a grating adjusting pond, an aeration tank, a first anoxic pond, a first aerobic pond, a second anoxic pond, a second aerobic pond, a precipitating pond, a flocculation reaction pond and a flocculation precipitating pond which are successively communicated. The multi-point water inflowing mode is adopted, water resources are reasonably utilized, and the system has the advantages of being low in cost, efficient, capable of resisting loading and impacting, stable in quality of discharged water, convenient to operate and manage, and beneficial for integrated construction and saving of occupied area.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an integrated small and medium-sized multi-point inflow deep nitrogen and phosphorus sewage treatment system and treatment method. Background technique [0002] With the expansion of the scale and quantity of urban-rural integration and the development of the rural economy, the popularity of flush toilets has increased, and the domestic water consumption of farmers has increased. This has resulted in the continuous increase of sewage discharge in rural areas. After being effectively treated, it is directly discharged into the surface, underground and rivers and lakes, causing serious pollution to local water sources and the living environment of residents, resulting in the deteriorating quality of rural water environment. [0003] Compared with cities, rural domestic sewage treatment has particularities: First, rural areas are characterized by wide distribution and scatt...
