Technical Field
The invention belongs to the technical field of sewage treatment, and particularly relates to a modular sewage treatment system, a treatment method and application thereof.
Background
Sewage treatment refers to a process of purifying sewage to meet the water quality requirement of discharging the sewage into a certain water body or reusing the sewage. The sewage treatment is generally classified into production sewage treatment and domestic sewage treatment according to the classification of sewage sources. The production sewage comprises industrial sewage, agricultural sewage, medical sewage and the like, and the domestic sewage is sewage generated in daily life, and refers to complex mixtures of various forms of inorganic matters and organic matters, and comprises the following steps: floating and suspended large and small solid particles; ② colloidal and gelatinous dispersions; ③ pure solution.
Rural sewage mainly comprises domestic sewage and agricultural wastewater. The domestic sewage has fixed component ratio, and mainly contains organic matters such as carbohydrate, protein, amino acid, fat and the like and pathogenic microorganisms; the agricultural wastewater has various components, and different treatment methods are needed for wastewater in villages and towns with different development targets in different seasons, different places and different development targets.
The pit is a small water source land with a water storage function formed by artificial excavation or natural formation, can be used for agricultural irrigation, planting and breeding, flood prevention and waterlogging elimination and the like, and can also play a role in conserving groundwater environment, improving regional microclimate and the like. For a long time, rural pond is mostly scattered and disorderly distributed because not unified, and falls into the smelly sump of rubbish deposit, holding sewage very much.
With the increasing demand of water environment treatment in recent years, new high-efficiency treatment technology is urgently needed for rural sewage and polluted water bodies such as ponds, lakes and the like.
At present, for rural sewage treatment, common domestic sewage conventional treatment processes comprise an activated sludge process, a biofilm process and the like, but the methods have the defects of large floor area, high investment cost, troublesome operation and the like. According to the characteristics of rural sewage water quality and water quantity, the characteristics of extremely low collection efficiency, small water quantity, high pollution degree, severe water quality and water quantity fluctuation and the like, the problems of lack of professional pipe transportation personnel, operation and maintenance cost and the like exist, meanwhile, the economical efficiency of investment and operation, the stability of a treatment process and the treatment effect are also considered, and the difficulties of rural sewage treatment are undoubtedly increased.
Water quality restoration of polluted pools, lakes and other water bodies mainly depends on two technologies of phytoremediation and microbial restoration. The plant restoration mainly comprises two forms of artificial wetland and ecological floating island, mainly depends on the enrichment and assimilation of plants to remove pollutants in water, and has the defects of low restoration efficiency, long required period, large occupied area, complex manual maintenance and the like; the microbial remediation mainly depends on two modes of exogenous microbial inoculum addition and endogenous aeration domestication to degrade pollutants in a water body, and has the defects of high cost, functional strain loss, poor impact resistance and the like, and the two technologies are both hindered to a certain degree in actual engineering popularization and application.
The prior Chinese patent application with publication number CN111018241A discloses a rural domestic sewage treatment system device, which comprises a water treatment system integration body, wherein the inside of the water treatment system integration body is sequentially provided with an adjusting tank, a biochemical tank and a planting tank; the upper part of the water treatment system integration body is provided with a solar power supply system, a micro-nano aeration system and an automatic control system; the biochemical pond comprises a filler frame, an aeration pipe, a sludge discharge pipe, a water outlet lift pump and a liquid level meter, and the planting pond comprises a floating island system, a filler frame, an aeration pipe, a sludge discharge pipe and a water outlet pipe; the rural domestic sewage treatment system device is powered by a solar power supply system. However, the aeration pipe in the technical scheme is directly laid below the bottom of the pool, all mud and water in the pool need to be completely emptied during maintenance, and the problems of complex operation and difficult maintenance exist during later-stage maintenance; and the whole pool is in a completely mixed strong turbulent flow state during aeration, and the flow state cannot be regulated and controlled.
