General Equipment Design For Water Treatment Plant In Mopanshan

Water supply system, as a civic infrastructure, is very important for national economy and the people's livelihood. The technology properties of the system have great influence for industrial productions and people health. Water treatment plant, the center of water supply system, assembled most high technology devices and insurance equipments. The water quantity, persistence and quality are all depend on it.The general design of the equipment for water treatment plant is based on the water amount in programming by considered with the overall planning of the project. And the next step is the general plan design and detail design for every subsystem.The overall plant distribution must be concision and compact to make full use of the planning land. The main process units should be separate definitely and can be centralized controlled expediently. Good greening is necessary to reform the working stations and depressing the influence of device noise. The district of advanced treatment system should be reserved for technology upgrade in the future. Based on the overall plant design, an optimized technological process is confirmed through a series of investigations studies.The sedimentation tank design is usually based on the ideal settler theory. The sedimentation tank design parameters is according to the quality of untreated water, sediment water and water temperature and can be chosen by references of simulated existing settlers. For inclined-tube sedimentation design, the parameter of tank can be determined by inclined-tube parameters, discharge and surface load. The filtration system design usually uses the phenomenological theory model. The filtering rate can be solved by Ives equations according to effluent and turbidity of raw water. The maximize size of rice coal and back flushing velocity can be get for the selected quartz sand maximize size.Sludge quantity is the main index for wastewater treatment system. The calculations of sludge quantity are refers to the empirical equations of UK, Japan and USA. The sludge dewatering treatment can adopt dewater after compress process or using integrative machine. The sludge compress can adopt gravity compress tank or concentrator. And the concentrator has the different styles such as centrifugal type and draper type etc.The main idea in the design process is multi-scheme comparisons, analysis and selected the best. Each candidate scheme is derived from proven technology and advanced design concepts overseas are also adopted by a lot of investigations in domestic and abroad.The pre-implemented is the most useful and effective for the whole project. The design stage has great influence for project cost. The determinations of final project are not only base on the base technology properties but also for the lower project and operation cost. Technology properties and project investment control are comprehensively considered for comparison analysis of equipment schemes. Then, the primary reference for alternative optimum procedure of final plan is the construction and operation cost. The prophase investment and predict cost were reduced with the precondition of system technology properties and the water price would be depressed by these methods.
