Check all valves to ensure that they are in correct states . open the high salinity water drain valve on the ro device 檢查所有閥門(mén),以確定閥門(mén)處于正確狀態(tài)。將ro設(shè)備上濃水排放閥打開(kāi)。
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 盡量降低設(shè)備的操作壓力,增加膜組濃水流量。設(shè)備在開(kāi)啟后應(yīng)盡量少停機(jī)。
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幾個(gè)時(shí)期由于夏季季風(fēng)的減弱,引起西南季風(fēng)流減少,從西邊過(guò)來(lái)的高鹽度水團(tuán)的減少使該區(qū)鹽度降低。
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 結(jié)果表明盡管土壤初始條件存在差異,但灌高礦化度水后,土壤含鹽量和溶液濃度總體增加,且土壤剖面特別是表層的sar明顯增大。
