Problems solved by technology

However, in order to maintain the long-term restoration effect, the existing microbial growth promoters generally contain high-efficiency bacteria that secrete biologically active substances, and are mainly used in micro-polluted water bodies such as groundwater and aquifers, as well as those affected by oil and specific organic substances. Polluted water bodies, most of the microbial growth promoters are still in the research stage, and there are few engineering ex

Embodiment Construction

[0029] At present, the apparent and main water quality indicators of the polluted water body before restoration are usually: the water body is black and odorous, the transparency is less than 5 cm, the biological species is single, large aquatic animals and plants disappear or are few, the pH value is weakly acidic, and the dissolved oxygen (D0 ) is less than 1.0 mg / liter (mg / l), chemical oxygen demand (COD cr ) and biological oxygen demand (BOD 5 ) up to 150-200 mg / l (mg / l) and 100 mg / l (mg / l), ammonia nitrogen and inorganic phosphorus up to 100 mg / l (mg / l) and 10.0 mg / l (mg / l) l).

[0030] See attached drawing 1. In the steps of inspecting and treating water bodies, analyzing the capacity of sewage reservoirs and the total amount of pollutants, and formulating restoration plans, it is necessary to fully inspect the polluted water bodies to be treated before in-situ bioremediation, and determine the capacity of sewage reservoirs and the total amount of pollutants Next, whe...

Abstract

The in-situ biological repairing method of polluted water body with composite enzyme biopromoter is to throw composite enzyme biopromoter in the amount and mode determined based on pollutant quantity to the polluted water body. The work flow includes the steps of: examining the polluted water body, analyzing the polluted water amount and total pollutant amount, determining the repair plan, establishing operation platform, and repairing the water body in different stages. The present invention has the advantages of restoring water self-cleaning capacity, restoring the natural ecological environment, low ecological risk and simple operation, and is suitable for treatment on different kinds of polluted water bodies.

Description

【Technical field】 [0001] The invention relates to the technical field of environmental protection, in particular, it is a method for in-situ bioremediation of polluted water bodies using a compound enzyme bioaccelerator, which is suitable for urban slow-flow, closed-type black and odorous rivers or eutrophication Environmental governance of river courses and large areas of polluted waters. 【Background technique】 [0002] According to statistics, more than 90% of urban rivers in China are currently polluted at different levels. In order to beautify the city and create a harmonious and sustainable living environment, it is necessary to treat the polluted water body. The use of remediation in situ organisms to treat polluted water is a newly developed technology in the field of environmental protection. Purification of water bodies through absorption, transformation, removal or degradation, has the advantages of less investment, high benefits, less environmental impact, less ...
