Method for remedying water environment pollution by utilizing mycorrhiza plants in combination with dominant microorganisms

Abstract

The invention relates to the technical field of water environment treatment, in particular to a method for remedying water environment pollution by utilizing mycorrhiza plants in combination with dominant microorganisms. The method comprises the following steps of (1) preparing an arbuscular mycorrhiza fungi inoculant; (2) inoculating the arbuscular mycorrhizal fungi inoculant to aquatic plants; (3) transplanting the mycorrhiza plants into a built ecological floating bed; (4) adding a dominant microbial agent into a water area to be treated; and (5) treating and repairing water environment pollution by combining a mycorrhiza ecological floating bed with the dominant microorganisms. According to the method, water pollution can be effectively treated, the cost is lower, and secondary pollution is avoided; the problem that the numerous existing aquatic plants cannot be effectively infected by arbuscular mycorrhizal fungi under the flooding condition can be solved; root systems of the aquatic plants can provide attached places, nutrient substances and oxygen for the dominant microorganisms and promote degradation of pollutants by the microorganisms; and the mycorrhiza aquatic plants and the dominant microorganisms are combined, so that the pollution remediation efficiency of the ecological floating bed system can be improved.

Description

technical field [0001] The invention relates to the technical field of water environment treatment, in particular to a method for remediating water environment pollution by using mycorrhizal plants combined with dominant microorganisms. Background technique [0002] With the development of economy and society, the pollution of water environment is becoming more and more prominent. A large number of pollutants enter the water body, and the microorganisms in the water body reproduce in large numbers, causing the water body to become anaerobic, black and smelly, leading to the death of aquatic animals, and causing the water body ecosystem to suffer. The destruction has seriously affected people's daily life, and the control of water pollution is urgent. At present, the main restoration methods include physical restoration, chemical restoration, biological restoration and some combined processes. Physical restoration and chemical restoration not only have high treatment costs, ...

Problems solved by technology

[0004] In order to overcome the shortcomings and deficiencies in the prior art, the object of the present invention is to provide a method for using mycorrhizal plants to combine dominant microorganisms to repair water environment pollution. The method can effectively control water pollution with low cost and environmental Friendly, no secondary pollution, can solve the problem that some aquatic plants cannot be effectively infected by arbuscular mycorrhizal fungi under flooding conditions, increase the resistance of aquatic plants, promote plant growth, and the huge root system of aquatic plants It can provide the place for the dominant microorganisms to attach, nutrients and oxygen, and can promote the growth and reproduction of the dominant microorganisms, thus promoting the degradation of pollution by microorganisms
