Embodiment 1

[0027] Embodiment 1 is used to improve the diversification microbial system of eutrophic water body

[0028] The composite microbial system provided by the present invention is composed of diversified bacterial agents and additives, and the bacterial agents are composed of Bacillus subtilis, Bacillus megaterium, Brevibacillus spores, lactic acid bacteria, Nitromonas, Bacillus licheniformis, Xylella viridans, Saccharomyces cerevisiae , Pseudomonas fluorescens, Rhodospirillum rubrum, Rhodopseudomonas palustris, Rhodobacter sphaericus, Pseudomonas putida. The quality ratio of each strain in the system is as follows:

[0029]Bacillus subtilis (ACCC 11060) bacteria solution 5-10 parts; Bacillus megaterium (ACCC 11107) bacteria solution 5-10 parts; 1-3 parts of liquid; 3-5 parts of Nitromonas (CGMCC 9412) bacterial liquid; 5-10 parts of Bacillus licheniformis (ACCC 10236) bacterial liquid; 1-3 parts of Viridans (CGMCC10922) bacterial liquid; (CICC 32355) bacteria solution 1-3 part...

Embodiment 2

[0035] Application Example 1 of Embodiment 2 Diverse Microbial System

[0036] The treated river section is about 600m. Before the treatment, the average river width of this river section was about 10 meters, with poor fluidity and weak self-purification ability. Very poor sense. Several major water quality indicators are inferior to the standard limit values ​​of Class V surface water, and the specific parameters are shown in the table below.

[0037] index Measurements Class V Water Standard Overrun Total Phosphorus 0.86 0.40 2.15 times total nitrogen 13.40 2.00 6.70 times Ammonia nitrogen 12.20 2.00 6.10 times COD 23.00 40.00 not exceeded transparency 32.00

[0038] At the beginning of October, the dosage of 1.5 grams of microbial products per cubic meter of water body will be released, and it will be supplemented once a month. The whole treatment cycle shared 45 kg of microbial products. After half a year...

Embodiment 3

[0039] Example 3 Application Example 2 of Diverse Microorganism System

[0040] The governed water body is a lake of about 0.3 square kilometers. Before the treatment, aquatic plants and algae were flooded, and the water body stinks in summer. Before treatment, the total phosphorus content was 0.17mg / L, the organic matter content was 40%, and the sludge depth was 50cm. During the treatment period, the dosage of 1.5 grams of microbial products per cubic meter of water body will be put in, and it will be added once a month. After four months of compound microbial feeding, the total phosphorus content, organic matter content, and silt depth were all significantly improved, down to 0.06mg / L, 15.6%, and 23cm respectively. See the water surface effect diagram before and after treatment Figure 4 and Figure 5 .

[0041] The two experimental data of the above-mentioned embodiment 2 and embodiment 3 show that the diversified composite microbial system in the present invention can...

Abstract

The invention belongs to the technical field of environmental management, and particularly relates to a diversified microbial system for improving eutrophic water and an application thereof. Accordingto the diversified microbial system provided by the invention, the adaptability of microbial products in different environments can be enhanced, so that the degradation stability of eutrophic water is improved. The problem that the existing microbial water purification technology is poor in adaptability and unstable in effect in different water qualities are solved. The microbial system providedby the invention comprises diversified microbial agents and an additive. The diversified microbial agents comprise bacillus subtilis bacterial liquid, bacillus megaterium bacterial liquid, brevibacillus laterosporus bacterial liquid, lactic acid bacteria liquid, nitration monad bacterial liquid, bacillus licheniformis bacterial liquid, trichoderma viride bacterial liquid, saccharomyces cerevisiaebacterial liquid, pseudomonas fluorescens bacterial liquid, rhodospirillum rubrum bacterial liquid, rhodopseudomonas palustris bacterial liquid, spherical rhodobacter sphaeroides bacterial liquid, andpseudomonas putida bacterial liquid. The additive comprises starch, diatomite, calcium carbonate and compound amino acid.

Description

technical field [0001] The invention belongs to the technical field of environmental treatment, and in particular relates to a diversified microbial system for improving eutrophic water body and its application. Background technique [0002] There are many measures and parameters of healthy water bodies. Among them, the content of organic nutrients such as nitrogen and phosphorus is an important indicator of sustainable ecology. However, the vigorous development and utilization of environmental resources in recent years has resulted in the discharge of a large number of nutrient-rich pollutants into various water bodies such as rivers and lakes. When the intake of nutrients exceeds the rate of natural circulation and metabolism in the water body, the water body will show eutrophication pollution. The water body polluted by eutrophication not only has bad smell and appearance, but also seriously affects the image of the water body. The unbalanced intake and consumption of n...
