Bioremediation treatment process for surface water with water blooms

Abstract

The invention relates to a bioremediation treatment process for surface water with water blooms. The bioremediation treatment process is a method for treating the water blooms by using microbial preparations made of algicidal bacteria, algicidal actinomycetes, biological compound enzymes and protozoa according to the actual condition that the content of nutrient salt in water bodies with the water blooms is high, and the treatment process is capable of inhibiting growth and reproduction of blue-green algae on one hand and cutting the nutrient salt which is required for the growth of the algae on the other hand. The bioremediation treatment process has high popularization values in treatment and maintenance of the water bodies with the water blooms.

Description

technical field [0001] The invention relates to a bioremediation treatment process for surface water blooms in rivers, lakes, etc., especially for moderately eutrophic water bodies with a pollution index between 50 and 70 and a low flow rate. These water bodies are often It shows that nutrients such as nitrogen and phosphorus are seriously exceeded. When the temperature rises in summer and the light is suitable, it may cause the rapid reproduction of algae such as blue-green algae and green algae, which in turn leads to the outbreak of large-scale algal blooms. And the present invention is to adopt biological method to carry out bioremediation control to the water body of outbreak algae bloom. Background technique [0002] With the improvement of people's living standards, the process of urbanization is accelerating, the per capita sewage discharge is also increasing, clean water resources are becoming increasingly tense, and surface water pollution is increasing. In many c...

The outbreak of algae blooms not only affects the landscape effect of the water body, but also secretes algal toxins during the continuous reproduction and growth of algae blooms. Algal toxins are harmful to the growth of most other aquatic organisms, and cyanobacteria die and rot. Negative impact on the water quality of the water body, aggravating water pollution

[0003] Once a large-scale outbreak of "water bloom" is formed in the water body (the total number of algae cells must exceed a certain concentration, greater than 10 million/liter, and the average chlorophyll content of the water body exceeds 0.06mg/L), if the physical method
