摘要
分析总结了杭州灯塔养殖总场沼气与废水处理工程的技术特点。该项目按照减量化、资源化、无害化的原则,优化了猪粪污水处理工艺和设计技术参数,解决了生物脱除氨氮的技术难题,在工程设计与施工中采用具有国际先进水平的Lipp制罐技术,提高项目的成套化和工程化水平。COD总去除率达98%,NH3-N去除率达99%以上,出水COD≤150mg·L-1,NH3-N≤15mg·L-1,出水达到《污水综合排放标准》的二级标准,日产沼气8500m3。
A biogas and wastewater treatment project treating pig dung and wastewater efficiently according to the principals of discharge reduction, resource utilization and zero-pollution discharge, is described in the present investigation. The facility optimizes treatment process, design parameters, and solving technical problems of bio-deamination and bio-denitrification. In addition, an international advanced Lipp tank making technology is utilized in the project. Removal ratios for COD and NH3-N reached to 98.5%, and 99%,respectively.The amounts of COD and NH3-N in outlet were found to be 150 mg·L-1 and below 15 mg·L-1, respectively with the biogas production of 8 500 m3 per day, mainly using for boiler, canteen and drying organic composite. Thus, the final discharge water reached the second grade standard of National Integrating Standards of Wastewater Discharge. This project is the pilot plant of UNDP/GEF.
