Abstract
According to the characteristics of quality and quantity of the wastewater generated from slaughterhouse and meat processing enterprises, on the basis of investigating the current status of wastewater treatment in the slaughtering and meat processing companies in Shenyang enterprises, the existing problems in some enterprises such as lack of wastewater treatment facilities, abnormal operation of the existing facilities and high running costs are analyzed and technical countermeasures are proposed. With regard to small-scale enterprises, according to their actual conditions, it is suggested that the wastewater be send to MSTP and the sediment be used as agricultural fertilizer. The primary process of artificial grid - oil separation - improved air flotation or the secondary process of artificial grid - oil separation - hydrolysis acidification - biological contact oxidation can also be used. With regard to large-scale enterprises, it is suggested that the process of coarse and fine screens - (skimming oil and scraping sediment) horizontal 2sedimentation - high efficiency floating - hydrolysis acidification - SBR/A O/biological contact oxidation -oxidation pond/artificial wetland/BAF be adopted.关键词
