Sludge unit enclosed tank type OAR treatment system

Abstract

The invention relates to a sludge unit enclosed tank type OAR treatment system. The system comprises fermentation tanks, a stone filter interlayer, a unit glasshouse, an aeration system and an automatic control system. The sludge unit enclosed tank type OAR treatment system has the beneficial effects that 1, the unit enclosed structure is capable of sufficiently utilizing the solar energy and the biological energy, and also capable of achieving the effects of heat preservation, thermal insulation, odor spillover prevention and the like, and the energy consumption is reduced and the operating cost is reduced, 2, the design of an obstruction door is advantageous for the hierarchical control of the material fermentation process and also advantageous for shortening the fermentation period and improving the processing capacity, 3, the feedback of a plurality of parameters and the adoption of the variable frequency technology are capable of realizing automatic accurate control of fermentation oxygen supply amount, and the controllers of a plurality of chambers can be networked to form a central control system, so that the labor intensity is greatly reduced, the efficiency is improved and the labor cost is reduced, 4, the number of the fermentation tanks can be increased or decreased according to the desired processing capacity, and the fermentation units are arranged flexibly to achieve the desired design requirements and to be suitable for large-scale sludge treatment, and 5, the processes are smooth in transition, simple to operate and simple and easy to maintain.

Description

technical field [0001] The invention relates to a unit closed tank type OAR treatment system, in particular to a low-consumption and high-efficiency urban sewage sludge resource utilization device, which is suitable for the treatment of urban sewage sludge and also for the treatment of urban and rural production and domestic organic waste . The invention belongs to the technical field of environmental protection facilities, pollution treatment and resource utilization. Background technique [0002] Municipal sludge is the sediment produced by urban sewage treatment plants after various levels of treatment to purify sewage, that is, the solid components in sewage. Sludge contains a large amount of N, P, K, Ca and organic matter, and N and P are mainly in organic state. At the same time, sludge contains a large number of pathogens, parasites (eggs), heavy metals and various toxic and harmful organic pollutants, often accompanied by foul smell, if it is piled up randomly, it ...

Problems solved by technology

However, the current sunshine shed fermentation tank technology is mostly dynamic stacking type or forced ventilation static stacking type in the shed. The surface of the fermentation tank is open and the space in the shed is large. It is impossible to reasonably control the microbial activity environment in the sludge fermentation process, and it is easy to generate odor. , and the degree of automation is not high; the energy consumption is large, the fermentation cycle is long, and the labor cost is high
