摘要:
中粮家佳康（赤峰）有限公司四期900 m3/d生猪养殖废弃物资源化利用项目，采用“减负还田”的工艺路线，养殖粪污经浓稀分流后，浓液进行厌氧发酵产沼利用，沼液用于灌溉；稀液经UASB+A/O大循环为主的生化处理后，可达到《农田灌溉水质标准》（GB 5084—2021）的旱作标准和《畜禽养殖业污染物排放标准》（GB 18596—2001），处理成本约9.25元/m3。该生化工艺具有占地面积小、二次提升能耗低、脱氮除磷效率高的特点，出水水质稳定，可为类似猪粪水处理项目提供参考
Abstract:
Taking a pig breeding waste utilization project with the capacity of 900 m3/d operated by COFCO Joycome Co., Ltd. in Chifeng as a case, the process of gravitational settling system is introduced for reducing the burden and returning to the field. The concentrated liquid is treated by anaerobic fermentation for biogas utilization and circular irrigation system of biogas slurry. Meanwhile the dilute liquid is biochemically treated by UASB and A/O large cycle process to meet the dry land crops criteria in Standards for Irrigation Water Quality (GB 5084-2021) and the Discharge Standard of Pollutant for Livestock and Poultry Breeding (GB 18596-2001). The treatment cost is about 9.25 yuan/m3. The process has the characteristics of small footprint, low energy consumption for secondary lifting, high nitrogen and phosphorus removal efficiency, and stable effluent quality, which can provide reference for similar pig manure water treatment projects.
