本钢污水处理厂V型滤池滤料板结 原因分析及解决措施 业 ●二 曲凤龙 玲 (本溪钢铁公司供水厂111700) 摘 要本钢污水处理厂V型滤池在2008年6月更换完滤砂后运行中出现阻塞值高、液位高，过水量减少现象， 滤池连续反冲洗后阻塞值仍然超过设定值150em，单个滤池停池检查发现滤料出现板结现象，如不及时解决，就会 使滤池严重堵塞、甚至会造成整个系统瘫痪，本文就V型滤池滤料层板结的原因进行了研究分析，并从运行管理方 面提出了防治V型滤池滤料层板结的措施。 Benxi wastewater ofVmodel to Steel strains treatementplant expect hardencase andsolvesmeasure study Qu Ling Fenglong，Lan (ThisBenxisteel ofwater 111700) factory supply companys AbstractThenativefilterof treatmentofVmodel inJune2008tostrain sewage plant changes sandrear in obstructionvalue is water operationappearance high，liquidpositionhigh，error reduces thecontinuousobstructionvalueafterrecoilwashesstillex— quantity phenomenon，filter to ceedstosetworth150 filter todiscoverthatstrain cm，singlestopspoolinspection expect，a— rise not filterseriousblock evencause harden solution，make phenomenon，asprompt up，can thefilterofVmodelto that entire tobe strainsfor systemparalysed，thispaper expectlayer harden has from reasonhascarriedoutresearch
