The filtration performance of jy discal filters and arkal discal filters are compared.based on different filtering accuracy,micron rating(20,55,100,200 μm),and different dosages of chemicals added to the influent,the parameter differences such as turbidity,suspended solids content,fpi value,head loss,filtration cycle,flux,backwash,etc.are compared and studied.the results show that these two kinds of filters have similar performance.

采用并联式的过滤系统，对国产的亚高牌叠片式过滤器与以色列arkal公司的叠片式过滤器进行了工艺性能比较试验。针对不同过滤精度(20、55、100、200μm)的叠片，在不同的加药量下，比较研究了两种过滤器进出水的浊度和悬浮固体含量、周期产水量、fpi值、水头损失、流量、反洗等工艺性能参数差异，试验结果表明，两种过滤器的性能大体相近。

The loss of the diesel soot and smoke Cha Cha PAHs in the leaching rate of the most important factor is the length of brewing time;PAHs were detected in the loop on the small number of PAHs,5 of the ring PAHs were only in the low level of test,and the experiment detected no PAHs, detected no 6 of the ring,regardless of diesel smoke or soot Cha Cha,the concentration of PAHs has the highest concentration of dihydrogen Acenaphthene;On the influence of the number of brewing tea,the total concentration and the leaching rate of PAHs in the soot and smoke Chai tea are lower than on the influence of the brewing time and temperature.

其中影响煤烟茶和柴烟茶中PAHs浸出率的最主要因素都是冲泡时间的长短；检测出的PAHs都集中在环数较少的PAH，5环的PAHs仅在较少的试验水平中检出，无6环的PAHs检出，无论煤烟还是柴烟茶中PAHs的浓度都以二氢苊的最高；在冲泡次数影响下，煤烟茶、柴烟茶中PAHs的总浓度和总浸出率，比在冲泡时间和温度影响下要低。
