Check all valves to ensure that they are in correct states . open the high salinity water drain valve on the ro device 检查所有阀门,以确定阀门处于正确状态。将ro设备上浓水排放阀打开。
Try to decrease the operational pressure of device and increase the high salinity water flux of membrane group . try to shut down as less as possible after device is started 尽量降低设备的操作压力,增加膜组浓水流量。设备在开启后应尽量少停机。
During the periods of 12ka , 60ka , 118 - 130ka , the decreasement of summer monsoon resulted in the decreasement of sw monsoon , then correspondingly , the less high salinity water mass make this area low salinity 在12ka 、 60ka 、 118 - 130ka 、 240 - 250ka几个时期由于夏季季风的减弱,引起西南季风流减少,从西边过来的高盐度水团的减少使该区盐度降低。
The results indicated that even if there was different at initial soil condition , such as initial moisture content and initial salt content , salt content in soil profile and sar at top soil increased greatly after the high salinity water infiltrated 结果表明尽管土壤初始条件存在差异,但灌高矿化度水后,土壤含盐量和溶液浓度总体增加,且土壤剖面特别是表层的sar明显增大。
