Description

Microbial reactor box with external aeration

Technical Field

The utility model relates to a microorganism sewage treatment device, in particular to a microorganism reactor box with external aeration.

Background

The water environment is an important foundation of human living environment and ecological environment, and water resources become a scarce precious resource in the world at present. At present, most of cities and towns and rural areas in China are wide in area, and due to the reasons of planning lag, disordered pollution discharge, treatment deficiency and the like, the water environment quality is generally poor, so that the living environment of residents in the cities and towns and the rural areas is seriously influenced, and the body health of people is further influenced.

At present, in cities and towns and rural areas, sewage mainly comprises a large amount of domestic sewage, industrial sewage and livestock breeding wastewater, under the condition that independent and effective treatment is not carried out on a single sewage body at the present stage, a plurality of polluted mixed water areas are formed, more serious damage is caused to water resources and water environment, serious pollution to black and odorous water body is caused, the black and odorous water body directly damages living health conditions of cities and countryside, the appearance and image of the cities and countryside are seriously influenced, and the development of city and countryside economy and the ecological civilization construction process are hindered.

In water pollution treatment, particularly black and odorous water body treatment, water bottom sludge is used as a main component of endogenous pollution, and due to the fact that a pollutant tight migration exchange relationship exists between the sludge and the water body, a large amount of deposited oxygen-consuming substances, nitrogen and phosphorus nutrients, organic pollutants and the like in the sludge continuously and repeatedly permeate the water body, so that the water body pollution is increased inevitably, and the treatment difficulty of the polluted water body is increased inevitably. At present, still basically, stop on the treatment method of artifical excavation submarine silt, the artifical excavation clearance cost a large amount of manpower and materials of submarine silt, the silt of clearing up moreover is piled up in large tracts of land on the bank and also can't be handled with reasonable low-cost, more has the potential harm that causes secondary pollution.

With the continuous development of environmental biotechnology, bioremediation technology is relatively widely applied to production practice as a treatment technology with low investment, high benefit and convenient operation, but most of the current common methods for treating underwater sludge by using microorganisms are to spray a microorganism preparation into a bacterial solution to pollute the water surface or to manufacture particles to be thrown into a polluted water body, and the two methods have obvious defects: (1) the speed of free diffusion of microorganisms to the sludge at the water bottom is slow; (2) the biological consumption is very large; (3) the subsequent cultivation domestication and the synergistic function are lacked. Therefore, the existing bioremediation technologies such as spraying bacteria liquid and scattering granular bacteria have the defects of low efficiency and large consumption.

However, at present, there is no good microbial reactor for rapidly, efficiently and inexpensively treating sludge of polluted water, and one of the main reasons is that the sludge layer at the bottom of the polluted water is lack of oxygen, and after microbial strains are output, because of no good living and breeding environment, the microbial strains freely reach the sludge at the bottom and breed slowly in the sludge layer, and the sludge is difficult to be rapidly and effectively treated.
