Composite microbial preparation for watershed bioremediation as well as preparation method and application thereof

Abstract

The invention relates to the field of bioremediation of rivers, and in particular relates to a composite microbial preparation for watershed bioremediation as well as a preparation method and application thereof. The microbial preparation comprises active ingredients including bacillus natto, candida utilis and rhodopseudomonas palustris which are mixed together in a volume fraction ratio of 1:1:1; the microbes for water treatment are combined with zeolite to prepare a comprehensive preparation for water treatment; the specific gravity of the obtained comprehensive preparation for water treatment is greater than that of water, so that the obtained comprehensive preparation for water treatment quickly sinks to the bottom of water and can not be washed away by water flow easily; the zeolite is used as a carrier for the microbes to grow, and can provide certain nutrition substances required by growth for the microbes while adsorbing pollutants, and the microbes attached to the zeolite perform decomposition and anabolism on the pollutants to ensure that the zeolite restores the adsorptive property, so that a virtuous cyclic process is formed. The microbial agent provided by the invention can adapt to fresh water and seawater environments at the same time, and has an effective bioremediation effect on watercourses of certain coastal cities, wherein the water quality of the watercourses has fresh water and seawater alternating conditions along with seasonal changes.

Description

technical field [0001] The invention relates to the field of river bioremediation, in particular to a composite microbial preparation for river basin bioremediation, as well as its preparation and application. Background technique [0002] The water in the river is flowing, and the ecological environment of the water body changes frequently, which has a great impact on the biological population in the water body, and its catchment area is large, so the non-point source pollution is very large, and it is more susceptible to the impact of point source pollution. Compared with rivers, lakes have large water surface, large storage capacity, stable water environment, small flow, and small catchment area. Therefore, the non-point source pollution and point source pollution of lakes are relatively small, and the water environment is relatively stable. easier to manage. Therefore, the management of rivers and lakes is different. At present, the restoration of ecosystems is mainly ...

Problems solved by technology

[0004] With the continuous improvement of people's research and understanding of the use of microorganisms, the harmfulness of pathogenic bacteria has been paid more and more attention while utilizing their beneficial effects; in terms of watershed bioremediation, the existing microbial agents are generally liquid agents and powders However, both liquid and powder bacterial agents are easily washed away by the water flow, which reduces the concentration of the bacterial agent in the water area, and the water quality treatment of the water area cannot achieve the expected effect; at the same time, some coastal urban rivers often appear The water quality of the river varies with the seasons, and the fresh water and sea water alternate. Therefore, for the bioremediation of this type of river, it is necessary to cultivate a bacterial agent that is suitable for both fresh water and sea water, but there is no report in the prior art
