Embodiment 1

[0060] The project is located in Maoming City, Guangdong Province. The project uses the biochemical system of the present invention to treat domestic sewage. The total number of workers within the collection range of the domestic sewage pipe network is 352 (64 households). The water quota for rural residents is 120L / person·d, and the sewage discharge coefficient 80%, the daily processing capacity can reach 40m 3 , see Table 1 for the treatment effect.

[0061] Table 1 is the parameters before and after domestic sewage treatment

Abstract

The invention discloses a distributed biochemical system used for processing domestic sewage. The distributed biochemical system comprises a biochemical tower and a constructed wetland; the biochemical tower comprises an equalizing tank, an anoxic pool, a sedimentation basin, at least two trickling filters, and a water collecting tank used for collecting discharged water of the trickling filters;the anoxic pool is connected with a first trickling filter through a first pipeline, and is connected with a second trickling filter through a second pipeline, and is also connected with itself through a first circulation pipeline; the water collecting tank is connected with the first trickling filter through a second circulation pipeline, is connected with the second trickling filter through a third circulation pipeline, is connected with the anoxic pool through a fourth circulation pipeline, and is connected with the sedimentation basin through a third pipeline. The distributed biochemical system is provided with the equalizing tank, the anoxic pool, the water collecting tank, the sedimentation basin, the constructed wetland, the trickling filters, and a pipeline system capable of realizing a plurality of functions for mutual cooperation, so that the whole trickling filtering and AO technology is completed, and the nitrogen and phosphorus removal effect of the whole technology is improved.

Description

technical field [0001] The invention relates to the technical field of domestic sewage treatment, in particular to a distributed biochemical system for treating domestic sewage and a domestic sewage treatment method. Background technique [0002] In recent years, my country has invested a lot of manpower and financial resources in the field of wastewater treatment. With the continuous advancement of water environment governance, the overall quality of water environment is stable and improving. At present, domestic and foreign domestic sewage treatment processes mainly adopt the traditional activated sludge process and its deformation processes, such as AO, A2O, inverted A2O, MBR and other biochemical system domestic sewage treatment processes. In the optimal state, the aerobic pool (O pool) is its important processing unit, and the energy consumption of oxygen supply accounts for 60-80% of the total energy consumption of the operation. The distribution of dissolved oxygen i...
