Embodiment

[0065] Treatment of the black and smelly river in the city:

[0066] The peripheral river of a residential area is about 3,000 meters long, 6-8 meters wide, 1-1.5 meters deep, and 0.5-0.8 meters thick. The river water pollution mainly comes from the domestic sewage discharge of surrounding residents. The water body is obviously black and smelly, and the transparency is relatively high. Low, black and smelly river bottom sludge and other pollutants.

[0067] According to the project implementation plan, before the river course is treated, the entire project treatment cycle is firstly divided into four stages, totaling about 7 months.

[0068] A. The pretreatment stage is completed in about 2 months. At this stage, the proliferation and expansion of microorganisms is completed, and the immobilization of microorganisms by zeolite is completed:

[0069] a1. Eliminate harmful factors for microbial reproduction and plant growth in the river, salvage the solid waste deposited in the...

Abstract

The invention discloses a zeolite immobilized microorganism and plant combined riverway pollution remediation method which comprises the following steps: A, a pretreatment stage, B, a biological treatment stage, C, a plant treatment stage and D, a later optimization stage, zeolite is used as a carrier, so that the problem of immobilization of microorganisms in water pollution remediation is solved; zeolite serves as a carrier and can provide attachment points for microorganisms, the hydraulic retention time of the microorganisms in the water body is prolonged, the treatment efficiency of the microorganisms is improved, through the synergistic effect of zeolite immobilized microorganisms and plants, the levels of COD, nitrogen, phosphorus and metal salt in the water body are reduced, the physical and chemical environment of the water body is improved, the growth of algae is controlled through the competitive relationship, and the long-term treatment effect is achieved.

Description

technical field [0001] The invention belongs to the technical field of environmental protection biotechnology, and in particular relates to a method for jointly repairing river channel pollution by zeolite-immobilized microorganisms and plants. Background technique [0002] With the acceleration of urbanization and the improvement of industrialization, river pollution has become a hot spot of concern. River sewage contains nitrogen, phosphorus, organic matter and other pollutants, causing eutrophication of water bodies, lowering of dissolved oxygen, and serious water pollution. environment, destroys the aquatic ecosystem, and causes the river to lose its self-purification ability, resulting in the black and odor of the river. Harmful gases released from polluted rivers seriously endanger the health of surrounding residents and affect the appearance of the city. [0003] With the continuous development of current technology, purely physical methods are difficult to fundament...
