Sanitary sewage photocatalysis and multi- medium advanced treatment system for single family in countryside

Abstract

The invention relates to an optical catalyzation and multi-media deep sewage treatment system used in independent houses in the village, and the system consists of a multifunctional deflection reactor, an optical catalyzation combined reaction pond and a multi-media hollow billet soakage system, wherein, the multifunctional deflection reactor consists of a collection pond, a precipitation adjusting pond and an anaerobic ferment pond; the optical catalyzation combined reaction pond consists of a pressurizing pond, an optical catalyzation filtering pond and a precipitation water-distribution pond. The water inlet of the collection pond is connected with a collection pipeline and the precipitation adjusting pond through a first hole plate. The precipitation adjusting pond is connected with the anaerobic ferment pond through a second hole plate. The anaerobic ferment pond is divided into an upper flow chamber and a lower flow chamber, with the upper flow chamber filled with paddings and the lower flow chamber connected with the upper flow chamber of an anaerobic filtering pond. The sewage forms water fog via a spray nozzle and enters into the optical catalyzation filtering pond, afterthe passage through a pressurizing pump and a pressure pipe. The invention has the following advantages that: first, the treatment is stable, and the applicability is strong; second, the dreg clearanceperiod is long and the maintenance is convenient; third, the utilization of the sewage as a resource can be achieved, and no any pollution is generated.

Description

technical field [0001] The invention relates to a process for the advanced treatment of rural single-household domestic sewage, and mainly relates to a photocatalytic and multi-media advanced treatment system for rural single-household domestic sewage. Background technique [0002] In recent years, the central and local governments have attached great importance to the "three rural" issues, and have done a lot of work in improving the living environment in rural areas, and achieved remarkable results. However, compared with cities, due to weak foundation, poor foundation, and wide distribution, At present, the infrastructure construction in rural areas of our country is very backward, the living environment is poor, and the hidden dangers and problems of environmental safety are prominent. The blue-green algae problem that appeared in Taihu Lake and Chaohu Lake in 2007 is a concentrated expression of eutrophication in water bodies. The state attaches great importance to the ...
