There is no significant difference in coagulation effect between PAC and PAFC. Taking cost into account, PAC was recommended. When the pH ranges from 6.5 to 7.5, the coagulation efficiency of PAC is better.

The principle model coupling is that water level, discharge and water quality simulated by the one-dimensional river network model and two-dimensional lake model are equal respectively at the junction section. Finite volume method is used to solve the governing equations of the model system. The developed model was applied in the Gehu Lake water system to simulate the hydrodynamic and water quality. Hydrology and water quality monitoring data of 2007 is used for the model calibration and validation. The good agreement of the calculated results with the measured shows that the model can be a effective tool for the water dynamic and water quality simulation of complex river network and lake-land regions.","PeriodicalId":6394,"journal":{"name":"2012 International Symposium on Geomatics for Integrated Water Resource Management","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90100936","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Through laboratory and field experiments, the program for the normal operation of the biological treatment along the Qinghai-Tibet Railway in low influent loading period has been got. The results show that imported high-efficiency microorganism can be used as vaccination microorganisms in the emergency situation; and efficient microorganisms combined with microbial immobilization technology can greatly enhance the effect of biochemical treatment and the ability of resistance to low influent loading; when the organic load was as low as 0.1kgCOD/m3·d around, operating intermittently with 12h as a cycle, aerating for 4h at least can achieve the highest COD removal rate, which can provide references for the operation and aeration time of the reactors in low organic load.

The normal diurnal pattern for water temperature was observed for the peat swamp forest drainage, but no diurnal pattern was evident in the dissolved oxygen data. The E. coli levels increased monotonically from the peat forest waters (0 colonies/100 mL) through the agricultural areas (100-2,000 colonies/100 mL) and the urban area (7,100 colonies/100 mL), and similarly pH increased along the same continuum.
