| 中文摘要 | 尿液源分离排水技术被视为是一种面向未来的可持续型排水技术,然而,尿液氨化过程导致的收集系统结垢和氮、磷损失等问题却严重限制了其推广和应用。针对这一问题,研究了尿液氨化过程的控制措施,并分析了对结垢潜势的影响。结果表明,5℃的低温对氨化过程的控制效果最好,25 d内氨化过程和结垢潜势都被完全抑制,但是可操作性较差;碱性p H值的调节虽然有助于氨化过程的控制,但是却加大了结垢潜势;投加脲酶抑制剂n BPT能在一定时间内控制氨化过程和结垢潜势,投加量为0.75%时,可以实现3 d的控制效果;投加量为1.5%时,可以实现7 d的控制效果。; Urine source separation has been considered to be a sustainable alternative for the traditional sewerage system.However,scaling on urine-collecting pipes and loss of nitrogen and phosphorus during urine ammonification limited the promotion and application of the new technique.Therefore,control of ammonification was investigated in laboratory scale,and the effect on scaling potential was analyzed.The results showed that low temperature of 5 ℃ could completely inhibit the ammonification process and the scaling potential in 25 d but with low operability.Further,the scaling potential was immediately increased although alkaline p H could inhibit the urine ammonification.Finally,dosing of urease inhibitor n BPT was found to be a possible approach to control urine ammonification.Dosage of0.75% was suggested for controlling ammonification for 3 d while dosage of 1.5% was suggested for 7 d. |
