Problems solved by technology

[0005] Although the prior art treatment methods for eutrophication of river water can achieve certain effects, due to the destruction of the original ecosystem and the lack of biodiversity, the impact of the river water system on the external environment lacks buffering capacity. Therefore, the river The treatment effect of the water body is difficult to maintain, and eutrophication pollution is prone to occur again

Embodiment 1

[0032] Example 1: Treatment of a middle drainage canal in Xiqing District, Tianjin

[0033] The industrial enterprises around the main canal discharge about 6,000 tons of industrial sewage and 9,000 tons of domestic sewage every day, and the pollution level of industrial sewage is very high.

[0034] After water purification and bottom mud treatment, the bottom mud turns yellow, the mud layer is obviously mineralized and stable, the water body gradually becomes clearer, the color gradually becomes lighter, the odor is weakened, and the water pollution indicators are gradually reduced. From figure 1 It can be seen that the treatment has achieved remarkable results, and the main pollutant indicators have dropped by more than 90%. At this time, the biological populations in the river began to prosper, algae began to grow, fish began to appear, and various plants on the shore also began to grow, and the biodiversity of the river ecology began to appear. In order to further promo...

Abstract

The invention provides an ecological restoring method of a river water body, comprising the following steps: (1) detecting pollution indexes of a river water body; (2) throwing composite microbial agents into a water body according to 5ppm to 9ppm; (3) transferring, translating and degrading matters in the river water body by the composite microbial agents; (4) throwing and/or planting water plants into a river; (5) detecting the pollution indexes of the river water body; and (6) repeating the steps from (2) to (5) from 15 days to 30 days until the river water body conforms to requirements. Each composite microbial agent comprises the components by weight percent: 5 to 10 photosynthetic bacteria, 10 to 15 bacillus subtilis, 5 to 10 nitrifying bacteria, 2 to 5 microzyme, 15 to 20 lactobacillus, 10 to 30 aspergillus, 10 to 30 acetobacter and 20 to 30 actinomyces. The ecological restoring method of a river water body aims at a river water body which carries out eutrophication treatment, leads the river water body to restore the bio-diversity of the river water body, radically restores ecology and has durable effect, low cost and simple use.

Description

technical field [0001] The invention relates to the technical field of ecological treatment, in particular to a river water ecological restoration method. Background technique [0002] The apparent characteristics of polluted rivers - black and smelly, are mainly caused by the enrichment of a large amount of nutrients imported from the outside in the water body. A large amount of pollutants are deposited to form silt. The pollutants in the water body consume the dissolved oxygen in the water body, and a large amount of good Oxygenous water body organisms began to die, while anaerobic microbial populations became very active, resulting in the production of hydrogen sulfide and other odors and many black metal sulfides, which destroyed the original ecosystem in the river channel and gradually deteriorated. Finally, the river lost its self-purification ability and gradually Become black and smelly. There are many factors affecting the governance of black and odorous rivers, an...
