Analysis on Optimal Water Quality Sources for Seawater Desalination in Hebei Coastal Waters
摘要
Abstract
In order to select the optimal water source for seawater desalination project in HebeiProvince,water intake tests were carried out in the coastal waters of Hebei Province in August2016.50 stations were set up and 50 water samples were collected.The sample tests included:pHvalue,turbidity,pollution index SDI,dissolved oxygen,free chlorine,manganese,iron,suspendedsolids,oil,and particle size of suspended solids.The evaluation results showed that the indicatorsexcept for suspended matter of coastal monitoring stations in Hebei Province can meet the LT-MED system of water requirement.The suspended solids exceed the standard in the west of Ca-ofeidian waters and east of Cangzhou waters,which can be pretreated by integrated efficient coag-ulation sedimentation equipment of Veolia.The east of the Daqinghe River waters can be pretrea-ted by general clarification filtration process.The results also showed that all stations could not satisfy the direct water requirements of RO system,but some stations could meet UF of RO pre-treatment device inlet requirements,whose most influencing index is turbidity.On the north side of Huanghua port,west of Caofeidian port,the Daqinghe River estuary and the Luanhe River es-tuary,the stations do not meet the requirements of the water inlet,while the other stations meet. The reverse osmosis is not suitable for the Cangzhou waters and the west of Caofeidian waters. The sea area from the east of Caofeidian to the Daqinghe River can take general coagulation,clari-fication,filtration treatment process.The east of the Daqinghe River can be pretreated by UF.关键词
