禽畜废水治理资源化利用工程设计

Utilization of Livestock Resources Wastewater Treatment Project Design

辽宁省铁岭市昌图县是国家的重点产粮大县,重要商品粮基地,丰富的农牧业资源促使禽畜养殖业发展较快,由于企业环境污染治理滞后,造成禽畜屠宰废水超标排放污染河水现象十分严重。设计中对粪便资源化利用、采取气浮-生物接触氧化的工艺流程来进行处理禽畜屠宰废水,处理禽畜废水规模1000吨/日,工程造价低,设备简单,建设周期短,出水水质能够满足排放标准需要,同时粪便资源化转变沼气、生态活性有机肥料也能产生可观的经济效益。

Changtu County of Tieling City, Liaoning Province, is the focus of major grain - producing counties, it is important grain production bases, rich agricuhural resources to promote faster development of livestock breeding industry, environmental management enterprises lagged behind, water pollution caused by slaughtering livestock wastewater discharge is a serious sub - standard. Design of waste resource utilization, take flotation - biological contact oxidation process for the wastewater treatment slaughtering livestock. 1,000 tons of livestock scale wastewater treatment/day, low cost, simple and short construction periods. effluent quality to meet emissions standards, while the shift of resources wastes gas Ecological activity can also have a considerable economic benefits of organic fertilizers.
