Ecological restoring method of river water body

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...
