In situ ecological restoration method of dominant microorganisms in river water pollution

Abstract

The invention relates to the field of canal treatment and specifically relates to a canal water pollution superior microorganism in-situ ecological restoration method. The canal water pollution superior microorganism in-situ ecological restoration method comprises the steps of measuring parameters of a canal water environment, acquiring and detecting a water sample, acquiring a bottom mud of a canal, preparing a microorganism domestication primary liquid, preparing an enrichment culture medium, domesticating the microorganism, preparing a solid inoculant, putting the solid inoculant into the canal, and detecting whether the parameters of the water sample reach the standards within 10-30 days and 80-90 days starting from the time when the solid inoculant is put. According to the method, the construction and operation costs are low, the construction is convenient and environment-friendly, and does not affect the surrounding resident and environments, the management and the maintenance are simple, no secondary pollution is caused, the purification and restoration effects are good, the self-cleaning capacity of a canal water body is strengthened after the treatment for half a year to one year, local grasses and creatures naturally grow and propagate, an original biologic chain is restored, and the purpose of in-situ biological restoration of the water environment is fulfilled.

Description

technical field [0001] The invention relates to river water pollution control, in particular to an in-situ ecological restoration method for dominant microorganisms polluted by river water. Background technique [0002] With the development of social economy and the improvement of people's living standards, the dense population brings domestic sewage, and the spread of small factories brings industrial wastewater. These untreated domestic sewage, untreated or untreated industrial production wastewater are also discharged with When the organic pollutants exceed the limit of natural purification that the river water body can hold, the dissolved oxygen in the water will be consumed rapidly and become anoxic, and the river water body will become eutrophic. The water body turns black and smelly. Due to the lack of oxygen, the survival of the original ecological organisms is directly threatened, until death, corpse decay, further pollution of the water body and stench, such a vici...
