【摘要】 畜禽养殖废水具有CODCr,NH₃-N,SS,以及致病菌含量高并伴有恶臭、水质水量变化大、处理难度大等特点。对于这类复合污染水体,采用单一物理、化学或生物等方法,难以修复或控制使其达标排放。为进行高效的废水处理,从组合工艺出发,对畜禽养殖废水处理系统进行综述,分析各组合工艺的优劣势以及在实际中的应用实例。并在此基础上,提出具有经济价值、处理效果好的组合工艺。更多还原

【Abstract】 Livestock wastewater contains high concentration of chemical oxygen demand,ammonia nitrogen,phosphorus and suspended solids and is accompanied by the stench, unstable water flow and difficulty in treatment. For this kind of wastewater, it is difficult to get repaired or controlled to reach the standard by complying single physical,chemical, or biological methods. In order to get the effective technology of livestock wastewater treatment, this paper summarized practical application of these methods in livestock farm wastewater treatment from the perspective of combined process, and analyzed their pros and cons. A combination process of economic value and effective treatment was proposed based on the analysis.更多还原
