Embodiment 1

[0045] according to figure 1 Construction and production of unit closed tank OAR treatment system for sludge fermentation.

[0046] The design height of stockpile is 1.5m, and the number of long slots is 4. Each fermentation tank is 60m in length, 6m in width and 4m in height, and the long tank is divided into 3 units by 2 partition doors. The unit sunshine shed adopts sunshine board and light steel structure, galvanized chain plate partition door; exhaust gas collection and negative pressure aeration pipe adopts PVC pipe; 1000mmx500mmx70mm; aeration device high-pressure centrifugal fan, secondary aeration pipeline, UPVC series pipe fittings; automatic control system adopts self-made PLC and self-made temperature probe, three units set different aeration process parameters according to the process; each unit is controlled locally The instrument is networked to the central control room. The compost turner adopts a track-type roller compost turner.

[0047] The working proce...

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 ...
