Effect of carbon source and nitrate concentration on denitrifying phosphorus removal by DPB sludge

Effect of added carbon source and nitrate concentration on the denitrifying phosphorus removal by DPB sludge was systematically studied using batch experiments, at the same time the variation of ORP was investigated.Results showed that the denitrifying and phosphorus uptake rate in anoxic phase increased with the high initial anaerobic carbon source addition. However once the initial COD concentration reached a certain level, which was in excess to the PHB saturation of poly-P bacteria, residual COD carried over to anoxic phase inhibited the subsequent denitrifying phosphorus uptake. Simultaneously, phosphate uptake continued until all nitrate was removed, following a slow endogenous release of phosphate. High nitrate concentration in anoxic phase increased the initial denitrffying phosphorus rate. Once the nitrate was exhausted, phosphate uptake changed to release. Moreover, the time of this turning point occurred later with the higher nitrate addition. On the other hand, through on-line monitoring the variation of the ORP with different initial COD concentration, it was found ORP could be used as a control parameter for phosphorus release, but it is impossible to utilize ORP for controlling the denitrificaion and anoxic phosphorus uptake operations.     

纳米零价铁改性膜强化厌氧生物处理氯酚废水

针对厌氧生物技术处理氯酚废水驯化周期长和纳米零价铁易团聚的问题,采用压滤法制备纳米零价铁改性聚偏氟乙烯膜（nZVI@PVDF）,并将其与厌氧生物体系耦合处理氯酚废水,通过序批实验探究nZVI@PVDF对耦合体系脱氯、水解酸化、产甲烷阶段的影响.结果表明,48h内,包含3种不同nZVI负载量（0.075,0.15,0.3g）的nZVI@PVDF膜耦合体系的2-氯酚（2-CP）去除率分别为99%、97.6%和91.8%,而未添加nZVI@PVDF的对照组仅为62.7%;72h内耦合体系的COD去除率分别为88.2%、89.1%、89.4%,而对照组COD去除率为63.6%;耦合体系的顶空甲烷占比分别为25.16%、25.98%、26.80%,而对照组仅为16.82%.投加产甲烷抑制剂的条件下,nZVI@PVDF刺激了脂肪酸的生成.nZVI@PVDF促进了氯酚的脱氯、脂肪酸和甲烷的生成.

Study of non-revenue water status and enforcement measures to reduce water loss: case study in villages of Kermanshah Province of Iran

In this study, the volume and the cash value of water loss, and reduction of water loss as a result of enforcement action during 2011–2013 in the drinking water network of villages in Kermanshah Province, Iran, have been investigated. Date collected by referring to the different parts of rural water and waste water company of Kermanshah Province and checklist were completed. The study showed the volume of produced water and sold water has increased and the water loss percentage has decreased. High cost of water production compared to revenue of sold water and water loss resulted in significant detriments in terms of the water production costs. Water loss level decreased from 33% to 30% as result of measures taken to reduce water loss but, it is still 15% higher than the world average level. Also the reduction in number of water resources and increase in the number and volume of reservoirs indicates a lack of water and a growing need. As result of high water loss, waste of costs in the contrast of water production cost and also because physical water loss accounts for most of the water loss of villages, necessary measures can be effective in reducing loss and have economic justification.
