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 equipment adopts the treatment process similar to urban sewage treatment plants, sludge return equipment, mixed liquid return equipment, pushers, agitators, advanced treatment and denitrification Various energy-consuming equipment such as filters are also used in process equipment, resulting in complex process equipment for rural sewage treatment, high energy consumption, and inconvenient management.

Embodiment 2

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

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

[0051] ② The outlet water of the grid adjustment tank is divided into two channels, the sewage accounting for 50-80% of the total water output enters the aeration tank as the first channel; the sewage accounting for 20-50% of the total water output enters the first channel as the second channel Anoxic pool, providing carbon source for initial denitrification and denitrification;

[0052] ③The sewage after denitrification treatment in the first anoxic tank enters the first aerobic tank for aeration treatment to further remove...

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...
