Integrated system for auxiliary material-free aerobic fermentation of organic solid waste

Abstract

The invention discloses an integrated system for auxiliary material-free aerobic fermentation of organic solid waste. The integrated system is characterized in that the whole technological process iscompleted in one building and is divided into an equipment room and a fermentation workshop. The system comprises a material receiving and mixing device, a material distributing and turning device, afermentation tank, an aeration device, a discharging device and a waste gas purification device. No auxiliary material is added in the technological process; the fermentation workshop adopts a reversehanging film structure, and the material distributing and turning device is formed by combining a rotating wheel type turning machine and a spiral material distributing machine; the tail end of the fermentation tank is also used as a decomposed material bin, and a tank bottom reciprocating type discharging machine is used for discharging; and a waste gas purification tower adopts chemical-standard-meeting structured packing or random packing, a large amount of circulating liquid is stored in the purification tower, and a nutrient solution is supplemented as required, so the circulating liquidcontains a large amount of microorganisms and is high in activity. The method has the advantages of simple process, low investment and operation cost, capability of being normally started and operated in cold regions, good fermentation effect, automatic operation, unmanned management, good waste gas purification effect and the like.

Description

technical field [0001] The invention relates to the technical field of organic solid waste treatment, in particular to an integrated system for aerobic fermentation of organic solid waste with zero addition of auxiliary materials. Background technique [0002] Aerobic fermentation is an effective method for treating organic solid waste. It can process organic solid waste through aerobic fermentation to realize the harmlessness, reduction, stabilization and recycling of materials. The final use is landscaping and land improvement. And making organic fertilizer etc. [0003] The existing domestic municipal sludge aerobic fermentation projects all need to add a large amount of auxiliary materials to the incoming materials, such as wood chips, peanut shells, corn straw powder, etc., and also need to add back-mixing materials. The auxiliary material has low density, is flammable, occupies a large area for storage, needs to be crushed, has poor safety, and increases the volume of...
