Problems solved by technology

[0003] CN104944711B patent has invented a water treatment method and its device based on the water ecosystem. In this invention, the sewage is collected and precipitated and introduced into the algae processor, then preyed by algae-eating insects, and then enters the artificial wetland system or the water ecosystem after treatment. The sewage treatment efficiency of algae and algae-eating insects is not high, and the artificial wetland treatment faces problems such as blockage

Embodiment 1

[0034] A method for treating micro-polluted water bodies with micro-pollution source water bodies in cooperation with water ecosystems, comprising the following steps: (1) centralized collection of micro-pollution source water bodies; (2) sedimentation treatment; (3) microbial aeration treatment; (4) using clear water type Water ecosystems undergo advanced treatment.

Embodiment 2

[0036] A method for treating micro-polluted water bodies with micro-pollution source water bodies in cooperation with water ecosystems, comprising the following steps: (1) centralized collection of micro-pollution source water bodies, during the centralized collection of micro-pollution source water bodies, sewage first passes through two thick and thin grids to intercept garbage and sundries, Then stay in the sump to precipitate fine particles; (2) sedimentation treatment, the size of the sedimentation tank is 5m 2 , depth 2m; (3) microbial aeration treatment, microorganisms adhere to the filler during treatment, the dissolved oxygen in the water body is 4mg / L, and the treatment time is 12h; The water area of ​​the system is 10 times that of the sewage, and the water inflow is 5% of the total volume of water in the clear water ecosystem.

Embodiment 3

[0038] A method for treating micro-polluted water bodies with micro-pollution source water bodies in cooperation with water ecosystems, comprising the following steps: (1) centralized collection of micro-pollution source water bodies, during the centralized collection of micro-pollution source water bodies, sewage first passes through two thick and thin grids to intercept garbage and sundries, Then stay in the sump to precipitate fine particles; (2) sedimentation treatment, the size of the sedimentation tank is 10m 2 , the depth is 1m; (3) microbial aeration treatment, the microorganisms are attached to the filler during the treatment, the dissolved oxygen in the water body is 2mg / L, and the treatment time is 24h; (4) the clean water type water ecosystem is used for advanced treatment. The water area of ​​the system is 20 times the amount of sewage, and the water inflow is 10% of the total volume of water in the clear water ecosystem.

Abstract

The invention provides a method for controlling a micro-polluted source water body by a water ecological system assisted by microorganism aeration. The method comprises the following steps of (1) centrally collecting the micro-polluted source water body; (2) precipitating; (3) microorganism aeration; (4) deeply treating by a clean water type water ecological system. The method has the advantages that the sewage is centrally treated by the microorganism aeration, the microorganisms are attached to a filler, the microporous aeration is adopted, the sewage treatment efficiency is higher, the problem of loss of microorganisms is solved, and one part of microorganisms is reserved in the sewage drained into the clean water type water ecological system and can continue to function; after the sewage is sent into the system, the sewage is properly adjusted and improved, and the clean water type water ecological system can automatically maintain running, so that the labor management cost is greatly reduced. The invention also provides a microorganism aeration device for implementing the control method. The microorganism aeration device has the advantages that the structure is simple, the installation is convenient, the cost is low, and the treatment effect is good.

Description

technical field [0001] The invention relates to a treatment technology for rivers, reservoirs and lakes with less pollution sources after large sewage interception, in particular to a method for treating micro-pollution source water bodies with a microbial aeration device combined with a clean water ecosystem and the microbial aeration device. Background technique [0002] The water quality of rivers, lakes and other water environments is deteriorating day by day. With the promulgation of the national "Water Ten Measures", my country has increased the comprehensive control of eutrophication and black odor in the water environment. The primary task of treating polluted rivers, reservoirs and lakes is to intercept sewage, eliminate pollution sources entering rivers, reservoirs and lakes on a large scale, carry out aquatic restoration and restore the ecosystem of rivers, reservoirs and lakes on the premise of intercepting pollution from external sources, and improve the self-pur...
