Embodiment Construction

[0018] The present invention is a bioremediation treatment process for black, odorous and eutrophic water bodies, as shown in the figure, and the specific implementation method is as follows:

[0019] (1) Source biological ecological interception system

[0020] An anaerobic biochemical pool is set at the sewage outlet on the river or lake bank. The anaerobic biochemical pool is a custom-made FRP tank reactor. The reactor is divided into a grid adjustment area, an anaerobic area, a contact reaction area and a sand filter area. Soft fillers are installed in the anaerobic zone and contact oxidation zone. The sand filter area is filled with sand and gravel. The lower layer is a gravel layer with a thickness of about 10cm-30cm, and the upper part is a sand layer with a thickness of about 80-150cm; PVC perforated water collection pipes are laid in the gravel layer. Sewage enters from the bottom of the anaerobic zone, and passes through the filler in the anaerobic zone and the fil...

Abstract

The invention relates to a black and odorous and eutrophication water body biological and ecological remediation and treatment process. The treatment process can carry out source biological and ecological interception on surface water pollution and is combined with terminal water body bioremediation. The invention can not only control pollution load entering a water body, but also beautify river way and revetment of lakes, and doesn't occupies need extra land. The water body biological remediation system can improve a water micro-ecosystem, restore water body biodiversity, improve the self-cleaning capability of the water body, and effectively improve the water quality of the water body. The invention has great popularization value on the treatment of surface water, especially urban rivers and lakes.

Description

(1) Technical field: [0001] The invention relates to a treatment process for surface water such as river courses and lakes, in particular to a treatment process for surface water with black odor, eutrophication and blue-green algae outbreak. (two) background technology: [0002] The pollution of surface water (including rivers and lakes) is mainly divided into two categories: one is exogenous pollution, that is, external factors such as sewage inflow and atmospheric deposition; the other is endogenous pollution, that is, due to pollutants in the water body The sediment formed by the residence and deposition of the sediment contains a large amount of pollutants and continuously releases nitrogen, phosphorus and organic matter into the water body. At present, the treatment means of surface water mainly rely on municipal engineering means, that is, sewage interception, bank revetment, dredging and water exchange. These methods have the following disadvantages: 1. The amount of ...
