Description

A kind of livestock and poultry feces thin liquid processing system shunted based on precipitating

Technical field

The utility model relates to the ecological energy environment-friendly type processing and utilizing technologies of livestock and poultry feces, specially a kind of based on precipitating The livestock and poultry feces thin liquid processing system of shunting.

Background technique

Aquaculture is an importance of modern agricultural development, and aquaculture development obtained very fast in recent years, with people The improvement of people's living standard, requirement of the people to livestock-raising is also higher and higher, to meat, milk, egg, fowl demand also increasingly Greatly.In recent years, because of the transformation of Agricultural production mode, livestock and poultry breeding industry is intensive, scale rapidly develops, and caused pollution is The problem of can not be ignored through becoming one.Pollutant source investigation dynamic renewal surveying statistics indicate that, 2010, national livestock and poultry breeding industry Chemical requirement, to account for the ratio of national total emission volumn be respectively 45%, 25% to ammonia nitrogen discharge amount, account for agricultural sources 95%, 79%, an important factor for Pollution from livestock and poultry has become China's environmental pollution source.

In order to reduce pollution of the livestock and poultry feces to environment, it is necessary to carry out effective processing to livestock and poultry feces and utilize.At present with Livestock and poultry feces are that raw material uses anaerobic fermentation technology production biogas, natural pond fertilizer to have become livestock and poultry feces resource utilization and innoxious place The main path of reason had both eliminated pollution of the livestock and poultry feces to environment, moreover it is possible to turn waste into wealth and produce clean energy resource --- biogas, together When the biogas residue, the biogas slurry that generate be also used as organic fertilizer for using in farmland.The utilization of this technology meets breeding enterprise itself Demand and national development ecological circulation agricultural economy requirement, national energy security is enhanced while preserving the ecological environment Supportability.

The core technology of livestock and poultry feces biogas project treatment process is anaerobic fermentation, higher for solid content at present Livestock and poultry feces pass through frequently with anaerobic fermentation equipment be thoroughly mixed formula anaerobic reactor, high concentration plug flow reactor, it is this kind of The relationship that the volume of anaerobic fermentation consersion unit increases with the proportional example for the treatment of for cow manure amount, volume of equipment size throw biogas project Money is affected；Simultaneously because the lower livestock and poultry feces of solid content directly carry out anaerobic fermentation its generate biogas slurry amount very Greatly, but its fertilizer efficiency index is lower, and general livestock and poultry farm periphery does not have enough consumption soils, and long distance transportation cost It is higher；The agricultural use of biogas slurry is subject to seasonal restrictions, and needs sufficiently large storage space, also results in the increase of cost of investment.It is practical On, cultivation industry is easy to be influenced by market fluctuation, can not put into a large amount of fund for livestock and poultry feces processing.In addition, with The reduction of livestock and poultry feces solid content, the utilization rate (i.e. unit volume factor of created gase) of anaerobic fermentation consersion unit also and then drop It is low；Biogas slurry is if it is considered that qualified discharge or to recycle then cost huge after directly being handled, if not can be carried out straight on the spot Utilization is connect, then it has surrounding enviroment and seriously threatens.So seeking an economic and practical livestock and poultry feces processing technique technique Route has become producer and administrative department urgently it is expected.

Livestock and poultry feces Reduction Technology is mainly separated the solid content in waste using solid-liquid separating equipment at present It carries out anaerobic fermentation production biogas or aerobic fermentation produces organic fertilizer, but its content of organics of the thin liquid of this process generation is high, Solid suspension content is also very high, and processing difficulty is larger, and processing cost is high, and will cause the wasting of resources.
