Research On Stone Machining Sewage Treatment Process And Filter Equipment

In recent years, China's stone processing and consumption develops by leaps and bounds, becoming a stone production and consumption power country. It spends a lot of water and produces large amounts of sewage containing powder during the stone processing. As we all know, our country is scarce of freshwater resources, if the stone processing sewage is disposed at will, it will damage the ecological environment seriously. Therefore, manufacturers of stone must be matched with Tower type stone processing sewage separation, purification and recycling system.It is a kind of equipment that deals with sewage produced in the procedure of processing stone. The main function of this equipment is separating and purifying sewage produced in the stone processing, isolating limestone from sewage to be used as raw materials of subsequent processing and recycling water after the separation.The research contents of this topic is how to separate sewage mud in stone processing produces, recycle the fresh water after the separation into the workshop by the pressure of water, press the mud into flat, recovery it after sucked dry by professional processing enterprise and make it into blocks (building materials) for again use. So as to achieve the water saving, avoid stone processing sewage water pollution and bad effect of sewage spillover on life and the environment, and overcome the disadvantage of low efficiency, covering a large area of traditional circulating water tank.The subject takes the domestic processing capacity of medium-sized enterprises as the basis to calculate technical parameters of the components of the equipment. This set of equipment is mainly divided into the following function units:water cycle unit, mud pressure filtration unit, solution adding unit, filter cake collection unit, electrical control unit. The design of equipment structure, is based on the enterprise status of stone sewage clean water tower the parameter design.Papers focus on the force analysis of purifying water tower and clean water tower, and describe the design, installation, verification and fault detection experiments rule of the stone processing sewage separation, purification and recycling system in detail.Through the experiment, using this set of stone processing sewage separation, purification and recycling system, there's a small amount of water in addition to the filter cake (negligible), all others will be recycled and reused, and achieve zero discharge of sewage. It has an advantage of great capacity of sewage disposal, compact structure, small area, low management fees, short time sewage purification and protection of human survival increasingly poor water etc. And it is the one of the best waste water treatment equipments in the stone industry.
