Along with the change of climate environment and the aggravation of interference of human production and life, the water quality of rivers and lakes is remarkably changed, the degradation of ecological systems and the eutrophication of water bodies become the problems commonly faced by the rivers and lakes, and the sustainable development of the environment is seriously influenced. Natural and healthy water is an ecosystem consisting of many living organisms. These living organisms are interdependent and in a balanced "life net" environment. This balance may be disrupted by excessive growth or reduction of some organisms, or may be disrupted by contamination. The specific expression is the symptoms of turbid water quality, peculiar smell and the like, and the eutrophic water body is difficult to live by fishes due to the lack of oxygen at the bottom of the lake because of floating algae on the water surface.

Through research, sediment accumulation of river and lake sediments is the root cause of water quality deterioration, but the traditional method for removing the sediment through excavation and transportation has the problems of high cost and secondary environmental pollution induction, in addition, the excavation cannot fundamentally improve the water quality, does not help the growth of fishes, treats the symptoms and the root causes, and the sediment accumulation problem can reappear after a period of time. Based on the above, the method of combining aeration and microbial inoculum feeding is adopted in the prior art to effectively degrade the bottom sludge of the rivers and the lakes, realize advanced treatment, fundamentally improve the water quality of the rivers and the lakes and reestablish a healthy ecological system. But current aeration and microbial inoculum are put in the device and are split type structure usually, are unfavorable for combining and using to the microbial inoculum is put in the device and is put in the effect that the microbial inoculum back microbial inoculum acted on the sediment poor, therefore administer the cycle length, and the treatment effect is not showing significantly.
