Problems solved by technology

However, in small towns far away from the city, rural areas, scenic spots, nursing homes, resorts, villas and other small areas where the population is concentrated, the sewage collection pipe network is not perfect, and the sewage treatment facilities are lacking. Water pollution not only quickly becomes "big pollution". Moreover, "big pollution" has become "big harm", which has seriously affected the regional water environment

Embodiment 1

[0027] A decentralized sewage treatment method, the decentralized sewage treatment system adopts a semi-ground design, and its structure is as follows figure 1 As shown, the sewage inlet pipe 1 is connected to the scattered sewage collection pipe, and the sewage is sent to the regulating tank 2. The regulating pond 2 can be implemented in the form of a pre-embedded glass fiber reinforced plastic water tank. 4 After separating the impurities with large particle size, use the sewage pump 3 to lift it to the non-clogging biological trickling filter 5, and use the water distributor 6 to evenly distribute the influent water in the packing module 7 installed on the packing support frame 8, and the sewage will flow from the long The biofilm-rich filler modules flow through 7, fully contact with the biofilm attached to the surface of the filler, and the COD or ammonia nitrogen pollutants in the sewage are adsorbed and further degraded by aerobic heterotrophic bacteria, nitrosobacteria ...

Embodiment 2

[0029] A decentralized sewage treatment method, the decentralized sewage treatment system adopts a fully buried design, and its structure is as follows figure 2 As shown, the sewage inlet pipe 1 is connected to the dispersed sewage collection pipe, and the sewage is sent to the regulating pool 2. The regulating pool 2 can be implemented in the form of steel concrete structure. After separating the impurities with large particle size, the sewage pump 3 is used to lift it to the non-clogging biological trickling filter 5, and the water distributor 6 is used to evenly distribute the incoming water in the packing module 7 installed on the packing support frame 8, and the sewage is abundant from the long-term The biofilm filler modules flow through 7, fully contact with the biofilm attached to the surface of the filler, and the COD or ammonia nitrogen pollutants in the sewage are adsorbed and further degraded by aerobic heterotrophic bacteria, nitrosobacteria or nitrifying bacteria...

Abstract

The invention relates to a decentralized sewage treatment method, which comprises that: a sewage inlet pipe (1) is connected with a sewage collection pipe; sewage is carried to an adjusting tank (2); large impurities are separated by a pump gate cover (4); the sewage is lifted into a non-clogging biotrickling filter (5) by a sewage pump (3) and uniformly distributed on a filler module (7) arranged on a filler support frame (8), and fully contacts with biomembranes attached to and grown on the surfaces of fillers to be purified; trickled water drained from the non-clogging biotrickling filter (5) is collected by a biotrickling filter water outlet groove (9), enters a dephosphorization groove (10) and contacts with a dephosphorization medium (11) for dephosphorization; and the dephosphorized water is drained from a water outlet pipe (12). The decentralized sewage treatment method saves the links of a secondary sedimentation tank, sludge concentration, sludge treatment and the like in a conventional sewage treatment process, simplifies a treatment flow and satisfies the needs of microorganisms in oxygen by natural ventilation oxygen supply; and the main unit equipment is modularly designed and simple in control.

Description

technical field [0001] The invention relates to a sewage treatment method, in particular to a decentralized sewage treatment method. Background technique [0002] With the rapid development of my country's economy, the problem of water pollution is becoming more and more serious. Large and medium-sized cities have sound sewage collection pipe networks, complete treatment facilities, and effective control and treatment of sewage from the source. However, in small towns far away from cities, rural areas, scenic spots, nursing homes, resorts, villas and other small populated areas, the sewage collection pipe network is not perfect, and the sewage treatment facilities are lacking. Water pollution not only quickly turns from "small pollution" to "big pollution". Moreover, the "big pollution" has become a "big harm", which has seriously affected the regional water environment. For example, the water environment problems in the Taihu Lake water system, Dianchi Lake water system, ...
