Exploration On Technology Of Aerobic Biology Treatment System Of Swine Manure On Intensive Scaled Swine Farms

With the development of the Livestock farms, not onLy the LeveL of peopLe's Life, the configuration of meaL and the income of peopLe have been improved graduaLLy, but aLso the structure of agricuLture has been adjusted. At the same time, a great deaL of muck and urine of Livestock has poLLuted the rivers, soiL and underground water. EspeciaLLy, with the scaLe and the degree of intensive of Livestock farms are extending confinuousLy, and more and more Livestock farms have been buiLded near the suburban of metropoLis and impacted area in China, which affects severeLy the Life of the inhabitant and the produce of the animaL theirseLves.Now the experts have researched deepLy the technique about wastewater of Livestock and figured that the poLLution of Livestock couLdn't depend on a singLe technique to handLe the wastewater of Livestock. They consider that the technoLogy to manage poLLution must be combined by the scaLe of the Livestock farms, the way of the cLearing wastewater, the characteristics of the muck and urine of Livestock, and the NationaL Standard of wastewater drainage.According to the opinions of experts, a new treatment system on swine wastewater is brought forward with the resuLt of the experiment: 1) According to the resuLt of experiment set a sedimentation pond that adopt a method with nature proceeds to deposition to reaLize soLid-Liquid separation before treatment system on swine wastewater. 2) Foreign microorganism have no an obvious exaLtation to removaL rates of COD of wastewater, so we can share profit to use the microorganism in swine wastewater to treat with swine wastewater. 3) Aeration can promote good oxygen microorganisms to decompose quickLy organic compounds in swine wastewater, but the cost of running of treatment system for swine wastewater is expensive, so we can suppLy super-speed bioLogy fiLter pond with equipment for sending the breeze and add ampLe oxygen to fiLL the pLace of aeration device. 4) EstabLish an oxidize pond in the end of the system for treatment of swine wastewater that can insure the swine wastewater reaches the state standard and reaLize" zero the row put". The project practice of swine wastewater treatment in Beijing Dongguangde pig breeding farm showed that the optimaL treatment system with the bioLogy fiLter pond that good oxygen Living creature is main can save the project investment, operating expenses, simpLify management and increase efficiency of removaL rates of COD. The removaL rates of COD were more 90% in efficiency bioLogy fiLter pond and the whoLe removaL rates of COD were 93%~97% of the new system. The resuLts of removaL rates of COD indicated that the new system form a comprehensive systemic engineering of excrement treatment and utiLization, and reach a high unity of economic, sociaL and ecoLogicaL benefits, on condition of guaranteeing the prerequisite that the discharged swine wastewater reaches the state standard aLL -sidedLy and swine manure is poLLutionLessLy treated.
