A method for ecological restoration and purification of landscape water environment

Abstract

The invention discloses an ecological restoration and purification method for landscape water environment which is characterized by comprising the following steps of (1) performing bottom mud sterilization and activation treatment; (2) splashing a microbial flora compound preparation; (3) reconstructing a submerged communities; (4) repairing an aquatic ecosystem food chain; and (5) performing aquatic ecosystem conservation management. According to the ecological restoration and purification method for the landscape water environment, a biological integrated control technology is applied, and the water purification effect is achieved by use of submerged plants; furthermore, decomposers, namely microorganisms in an ecosystem are fully utilized, and multiple types of aquatic animals are put in the aquatic ecosystem, so that the ecosystem food chain is perfected, various aquatic species promote and restrict one another, the whole riverway, lake, pond and wetland system is kept in dynamic balance for a long time, the original self-purification capability of the aquatic ecosystem is restored, and a long-term stable effect is achieved.

Description

technical field [0001] The invention belongs to the technical field of water environment treatment, and in particular relates to an ecological restoration and purification method of landscape water environment. Background technique [0002] At present, with the rapid development of modern cities and the improvement of industrial and agricultural production levels, the pollution of rivers, lakes, ponds, and wetlands is becoming more and more serious, and the black and smelly phenomenon is obvious, which seriously affects the quality of life of urban and rural residents. The main causes of black and smelly rivers, lakes, ponds, and wetlands are: [0003] (1) Water environment pollution load is too heavy. Due to the inadequate construction of urban and rural sewage pipe networks, the establishment and operation of sewage treatment plants failed to meet expectations, workers leaked and leaked seriously, and a large amount of industrial wastewater, domestic sewage, rainwater, ga...

AI Technical Summary

Problems solved by technology

[0003] (1) Water environment pollution load is too heavy

Due to the inadequate construction of urban and rural sewage pipe networks, the establishment and operation of sewage treatment plants failed to meet expectations, workers leaked and leaked seriously, and a large amount of industrial wastewater, domestic sewage, rainwater, garbage and farmland fertilizers were directly discharged into rivers, lakes, and ponds without treatment. , Wetland, so that the organic pollution load far exceeds the self-purification ability and environmental capacity of the water body itself, resulting in severe hypoxia in the water body

[0004] (2) The supply water source is polluted, and the bottom mud is seriously deposited

The water source used for water diversion and water exchange is polluted, so that it is impossible to restore the landscape water environment through water exchange. After long-term accumulation, the bottom mud is seriously silted

[0005] (3) Poor fluidity of river courses, lakes, ponds, and wetlands

[0008] Using biological comprehensive ecological restoration and purification technology, that is, by relying on microorganisms, submerged plants, and aquatic animals to reconstruct the complete ecosystem of rivers, lakes, ponds, and wetlands, and using the self-organized and efficient purification capabilities generated by the water ecosystem to govern the landscape The water environment is not widely used, and some are limited to a single artificial wetland (emergent or floating plant) treatment method. The purification system lacks biodiversity and is easily disturbed and affected by the external environment. It cannot achieve long-term stability. The water quality transparency cannot exceed 0.9 meters, let alone the "Surface Water Environmental Quality Standard" (GB3838-2002) III or above
