Research On The Excrement And Biogas Treatment Of Scale Pig Farms

As the world economy to move forward continuously, some global crisis is increasinglysignificant.Energy shortag、the destruction of the ecological environment seriously affect the healthydevelopment of human society.Animal husbandry has developed rapidly in our country, some smalland medium-sized farms number is increased, and the lag of waste treatment technology andequipment, waste is wanton piled up on farms run itself and the surrounding ecological environmentcaused serious influence.This paper makes research on the scale of farm manure biogas utilization,toseek a way that not only can solve the problems caused by scale piggery wastewater pollution, butalso can produce energy, biogas slurry, biogas residue, and the rational use of low cost, highefficiency, ecological environmental.This paper chose142wizard in Shihezi Xinjiang animal husbandry farms and Xinjiang Shiheziagricultural built through the joint efforts of the new technology base，Monitoring the two pig farmsof biogas engineering,Get a lot of valuable data， To deal with the data analysis, conclude theadvantages and disadvantages,And in two project benefit evaluation from the aspects of economy,environmental protection.The analysis thinks, two projects have taken a warming and insulationmeasures, ensure the normal operation of Engineering in cold winter climates.From the point of heatpreservation on the cost of warming,The former engineering has obvious advantages.Monitoringshows that Two engineering both have good removal effect to CODcr, BOD5,But the latter has abetter treatment effect.there are still some gaps between treated water and Pollutant emissionstandards of the livestock and poultry industry.Through the analysis of two engineering,Comprehensiving scale pig farms pool constructionsituation,A housing digester matching scheme is proposed. This paper Optimize the engineeringFrom the Angle of gas storage, feed location, feeding tube and the bottom Angle,Make a scale pigpool design more reasonable and feasible, energy-saving and efficient.Process model is still usingthe ecological process of more mature now,Increase high quality vegetable base and pickorchards,Fermentation combined with planting.High quality vegetables and fruit planting base is anew economic growth point.This method is a kind of applicable to small and medium-sized farms oflow cost, high efficiency of agricultural ecological model.
