Problems solved by technology

However, in the actual river course treatment, since most of the pollutants exist in the sediment, the restoration effect of direct injection of microbial agents is not ideal; For a long time, secondary pollution may also be formed; the fluidity of the river water will also lead to the spread of microbial agents, resulting in poor repair effects and other problems

Embodiment 1

[0047] When anaerobic bacteria are used as the microbial expansion culture solution, in order to repair the ammonia nitrogen and total phosphorus indicators of the river water in the 1km section of a navigable river, so that the river water indicators near the automatic monitoring station can reach Class III water indicators, a pollutant in the river The method of microbial treatment and purification is applied therein, and its specific operation steps are as follows:

[0048] (1) In the expansion device (1.5m 3 Volume) into the river sewage (1m 3 ) and nutrients (20kg), and then put the compound microbial agent (150L) into the expansion device to carry out the field expansion of the microbial solution;

[0049] (2) Place the adsorption materials (malachite, activated carbon, zeolite, etc.) and biological ropes, artificial aquatic plants, etc. in the microbial bacterial liquid after expansion and let stand for 1-2 hours for microbial adsorption;

[0050] (3) Place the adsorp...

Embodiment 2

[0059] When aerobic bacteria are used in the microbial expansion culture solution, in order to repair the excessive ammonia nitrogen and total phosphorus concentrations in the river water of a certain landscape river channel at a distance of about 500m, so as to make it reach Class III water indicators, a microbial treatment and purification of pollutants in the river channel The method is applied therein, and its specific operation steps are as follows:

[0060] (1) In the expansion device (1.5m 3 Volume) into the river sewage (1m 3 ) and nutrients (10kg), and then put the compound microbial agent (100L) into the expansion device to carry out the field expansion of the microbial solution;

[0061] (2) Place the adsorption materials (malachite, activated carbon, zeolite, etc.) and biological ropes, artificial aquatic plants, etc. in the microbial bacterial liquid after expansion and let stand for 1-2 hours for microbial adsorption;

[0062] (3) Place the adsorption device wi...

Abstract

The invention relates to a microbial treatment method applied to riverway section restoration. The method comprises the following steps: S1, expanding culture of a microbial liquid; S2, carrying out microbial adsorption; S3, performing internal installation and placement of an adsorption device; S4, spraying the microbial liquid; S5, detecting; and S6, carrying out analysis and adjustment. The screened complex microbial inoculant (including various strains such as efficient heterotrophic nitrification-aerobic denitrification strains-Raoultella, Pseudomonas, photosynthetic bacteria, Bacillus and the like) is used as a bacterial source, and the bacterial source is sprayed into a river channel provided with an adsorption device after culture expanding to purify overproof pollutants in river water. The riverway treatment method has the advantages of simple and convenient operation, high efficiency, good treatment effect and the like.

Description

technical field [0001] The application relates to a method for microbial treatment applied to river section restoration, which belongs to the technical field of environmental microbes. Background technique [0002] At present, with the rapid economic development, environmental pollution is becoming more and more serious. High-speed economic development is often at the expense of the current resource environment. The pollution of soil and water, especially the pollution of river water, has seriously affected people's health and the surrounding living environment. [0003] There are many ways to restore polluted rivers. The commonly used purification methods mainly include physical treatment and chemical treatment. However, they all have the characteristics of high technical requirements, complicated construction, huge investment, and secondary pollution, making it difficult to implement them on a large scale. Microbial treatment, as a green and environmentally friendly new ...
