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 like figure 1 As shown, the sewage inlet pipe 1 is connected with the dispersed sewage collection pipe, and the sewage is sent to the regulating tank 2. The regulating tank 2 can be implemented by a pre-embedded glass fiber reinforced plastic water tank. After the sewage passes through the regulating tank 2 to homogenize the water quality and quantity, it passes through the pump grid 4 After separating the large-particle impurities, use the sewage pump 3 to raise it to the non-clogging biological trickling filter 5, and use the water distributor 6 to evenly distribute the incoming water in the packing module 7 installed on the packing support frame 8. The biofilm-rich packing modules 7 flow through and fully contact the biofilms attached to the surface of the packing. The COD or ammonia nitrogen pollutants in the sewage are adsorbed by aerobi...

Embodiment 2

[0029] A decentralized sewage treatment method, the decentralized sewage treatment system adopts a fully buried design, and its structure is like figure 2 As shown, the sewage inlet pipe 1 is connected with the dispersed sewage collection pipe, and the sewage is sent to the regulating tank 2. The regulating tank 2 can be implemented in a steel concrete structure. After the sewage passes through the regulating tank 2 to homogenize the water quality and quantity, it passes through the pump grid cover 4 After separating the large-particle impurities, the sewage pump 3 is used to raise it to the non-clogging biological trickling filter 5, and the water distributor 6 is used to evenly distribute the influent water in the packing module 7 installed on the packing support frame 8. The sewage is abundant from growth The filler modules 7 of the biofilm flow through and fully contact the biofilm attached to the surface of the filler. The COD or ammonia nitrogen pollutants in the sewage a...

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 has become increasingly serious. Large and medium-sized cities have complete sewage collection pipe networks and complete treatment facilities, and sewage can be effectively controlled and treated from the source. However, the sewage collection pipe network of small towns, rural areas, scenic spots, sanatoriums, resorts, villas and other small population clusters far away from cities is not sound, and sewage treatment facilities are lacking. Water pollution not only rapidly changes from "small pollution" to "large pollution", Moreover, the "big pollution" has become a "big hazard", which has severely affected the regional water environment. For example, the water environment of Taihu Lake, Dianchi Lake, Chaohu Lake, Yellow River Basin, ...
