Embodiment 1

[0039] This embodiment is used to improve the ecological ditch system for the treatment of non-point source pollution in receiving water bodies, including settling tanks arranged in sequence in the direction of non-point source and incoming water for sedimentation of solid substances such as silt carried by non-point source and incoming water, for An ecological purification area for removing some pollutants from non-point source water. Above the sedimentation tank is a basket grille device for intercepting suspended solids in the water. The non-point source water enters the sedimentation tank after passing through the basket grille device. The purification areas are connected by a water distribution flower wall of brick structure, and the water distribution wall is provided with reserved holes to ensure hydraulic conditions, and the ecological purification area is filled with biosorption fillers as microbial carriers.

[0040]In this embodiment, three treatment units, namely th...

Embodiment 2

[0042] Such as Figures 1 to 4 As shown, this embodiment is used to improve the ecological ditch system for the treatment of non-point source pollution in the receiving water body, including sedimentation tanks arranged in sequence in the direction of the non-point source and incoming water for sedimentation and other solid substances carried by the non-point source and incoming water. 2. An ecological purification zone 3 for removing some pollutants from non-point source water. Above the sedimentation tank, there is a basket grille device 1 for intercepting suspended solids in the water. The pool, the sedimentation tank and the ecological purification area are connected by a water distribution flower wall of brick structure. The water distribution wall is provided with reserved holes to ensure hydraulic conditions. The ecological purification area is filled with biosorption fillers as microbial carriers.

[0043] In this embodiment, the basket grille device includes four gril...

Abstract

The invention relates to an ecological ditch system for improving receiving water non-point source pollution treatment, and effectively solves the problem of how to effectively utilize the ecological ditch technical measures to treat receiving water non-point source pollution. The ecological ditch system for improving receiving water non-point source pollution treatment includes a sedimentation tank for precipitating silt and other solid matters carried by non-point source inflow water, and an ecological purification area for removing part of pollutants in non-point source inflow water, the sedimentation tank and the ecological purification area are arranged along the flow direction of the non-point source inflow water in order, a basket grating device for intercepting suspended matters in water is disposed above the sedimentation tank, non-point source inflow water enters the basket grating device and then enters the sedimentation tank, the sedimentation tank and the ecological purification area are connected by a brick structure water distribution perforated wall, the water distribution perforated wall is equipped with reserved holes ensuring hydraulic conditions, and the ecological purification area is filled with a biosorption filler serving as a microbial carrier. The system provided by the invention can treat non-point source pollution, and reduces the pollution load of pollutants to receiving water.

Description

technical field [0001] The invention relates to a technology for improving the treatment of non-point source pollution of receiving water bodies, specifically an ecological ditch technology. Background technique [0002] In recent years, due to the acceleration of agricultural production activities and urbanization in my country, urban hard roofs, rainwater runoff from roads, domestic sewage, agricultural fertilizers, pesticides, and livestock and poultry manure pollution, along with the precipitation or irrigation process, have a negative impact on the recipients. The water body is seriously polluted, and the excessive nitrogen and phosphorus brought by the non-point source water cause the eutrophication of the receiving water body, which not only brings extremely poor sensory experience to the masses, but also a prominent water environment problem that directly affects the production and life of the masses. . [0003] The "Water Pollution Prevention and Control Action Plan"...
