CASS工艺处理规模扩容的实例研究 总被引:1,自引:0,他引:1
结合中山市小榄污水处理厂CASS工艺的实际运行情况,开展了污水厂挖潜扩容的生产性试验研究。结果表明:CASS池运行优化后,能够实现每两格同步运行,处理规模从11.2×104 m3/d提升至15.84×104 m3/d,出水水质能够满足GB 18918—2002一级B标准和广东省地方标准;在该工况下进一步增加污泥回流,强化除磷使出水TP降到0.5 mg/L以下,出水水质可达到GB 18918—2002一级A标准。扩容后电费总成本为22 120元/d,单位处理电费成本为0.103 6元/m3,虽然电费总成本较扩容前增加,但单位处理电费成本较扩容前降低了0.007 4元/m3。 相似文献

The rise of Internet of things technology, wireless communication and computer technology in recent years has attracted
the scientific community's attention to wireless sensor networks, and the study of reasonable distribution coverage of detection areas.
It is also necessary to maximize coverage.Artificial bee colony algorithm is a kind of optimization method which imitates the bee be-
havior. It can obtain more superior convergence results for unconstrained numerical optimization problems. Because the existence of
artificial bee colony algorithm is easy to be limited to the local optimal solution, the process of the intermediate stagnation problem,
the need for a longer search time, an improved artificial bee colony algorithm is proposed, which can speed up the convergence
speed in the later stage. The improved artificial bee colony algorithm can effectively reduce the redundancy and prolong the lifetime
of the sensor network by optimizing the node coverage. 相似文献

PAC/MBR用于微污染地表水处理的中试研究 总被引:1,自引:1,他引:0
采用投加粉末活性炭(PAC)的膜生物反应器(MBR)组合工艺-PAC/MBR处理微污染地表水.中试结果表明,该工艺出水水质稳定,稳定运行期间出水浊度、CODMMn和氨氮分别保证在0.3 NTU、1.9 mg·L-1和0.2 mg·L-1以下,达到生活饮用水卫生标准的要求.膜表面生物活性炭(BAC)滤层具有良好的抗压性,出水通量呈阶梯式下降,防止了持续性的大幅度衰减.混合液中悬浮态PAC和生物活性炭能吸附大部分胞外聚合物(EPS),降低溶解态胞外聚合物含量,有利于减缓膜污染. 相似文献
