一个先进污泥减小过程,我。e。污泥减小和磷的移动过程,被开发。结果证明那优秀污泥减小和生物磷的移动能在这个系统完美地被完成。什么时候化学的氧需求ρ(货到付款) is332 - 420 mg/L ,氨ρ( NH_3-N 的集中)是 30 -全部的磷的ρ( TP 的 40 mg/L 和集中)是 6.0 - 9.0 mg/L 在流入,系统仍然保证ρ(货到付款)< 23 mg/L ,ρ( NH_3-N )< 3.2 mg/L 和ρ( TP )<在自河的 0.72 mg/L 。除以外溶解的氧ρ(的集中) 在 1.0 mg/L 附近,污泥生产是有 1 g 货到付款的消费的不到 0.140 g,并且磷的移动超过 91% 。另外, 48.4% 全部的氮被同时的氮的硝化作用和脱氮作用移开。
An advanced sludge reduction process, i.e. sludge reduction and phosphorous removal process, was developed. The results show that excellent sludge reduction and biological phosphorous removal can be achieved perfectly in this system. When chemical oxygen demand ρ(COD) is 332 - 420 mg/L, concentration of ammonia p(NH3-N) is 30 - 40 mg/L and concentration of total phosphorous p(TP) is 6.0 -9.0 mg/L in influent, the system still ensures ρ(COD)〈23 mg/L, ρ(NH3-N)〈3.2 mg/L and ρ(TP)〈0. 72 mg/L in effluent. Besides, when the concentration of dissolved oxygen ρ(DO) is around 1.0 mg/L, sludge production is less than 0. 140 g with the consumption of 1 g COD, and the phosphorous removal exceeds 91 %. Also, 48.4% of total nitrogen is removed by simultaneous nitrification and denitrification.
