基于短程硝化-厌氧氨氧化的组合工艺处理餐厨废水效能研究
Study on the efficiency of the combined process for treating kitchen wastewater based on partial nitrification-anammox
摘要
Abstract
With the increase of kitchen waste production,the quantity of kitchen wastewater is also increasing.However,the quality of kitchen wastewater is complex,and the concentration of pollutants such as oil,SS,COD,and ammonia nitrogen is high.How to treat kitchen wastewater efficiently and economically has become a challenge.A combined process of"dissolved-air flotation,anaerobic,anoxic,DO-liminted and oxic"had been developed to treat kitchen wastewater at a certain Hermetia illucens breeding base by this pilots system.The pilot system had a scale of 4 t·d-1.When running for 113 d,the average removal rates of COD and TN in the biochemical section reached 94.3%and 98.2%respectively.The average TN removal rate and average volumetric removal load of the DO-limited reactor reached 79.4%and 0.29 kg·(m3·d)-1,respectively.The concentration of anammox granular sludge in the DO-limited reactor was stable at over 1 000 mg·L-1,proving that the DO-limited reactor had good ability to cultivate and intercept anammox granular sludge.This combined process had excellent and stable performance for nitrogen and carbon removal in an energy and medicament saving way,providing a new way for the treatment of kitchen wastewater.关键词
