At present for the Separation of Solid and Liquid process of this type of wastewater suspended substance, apply more natural sedimentation method.Existing sedimentation basin mainly contains rectangular sedimentation tank, vertical sedimentation basin, radical sedimentation basin and ramp type sedimentation basin, wherein vertical sedimentation basin due to its floor space little, treatment effect is better used widely.But vertical sedimentation basin is only applicable to process less water yield waste water, to adaptability and the buffering ability of water yield change, in precipitation process, most of fine suspension cannot be able to be removed along with bubble floating, and water outlet BOD, ammonia nitrogen, suspension (SS) etc. are still higher.
Filtration is also a common method of Separation of Solid and Liquid process.Existing filter method mainly contains diagrid filtration, micro porous filtration, membrane filtration and in-depth filtration.Existing filler mainly contains quartz sand, anthracite grain, magnet ore particle and dolomite grain etc.General filtering ponds need to be made up of filter course, padding layer, water distribution system and rhone, and dirt, by filtering and two stages of backwash, is first retained by filtration stage, is separated by dirt by the backwash stage with filtrate by whole process.Whole process influence many factors, as filtrate proterties (size, shape, porosity, thickness surface character), suspension proterties (size, shape, concentration, surface nature), the control of the vapour lock that anaerobic processes generation bubble causes and backwash process.In a word, filtration treatment method is more complicated, and the more difficult control of process, and filtrate needs not timing to change, and cannot be applicable to that the water yield is large, the Chinese turtle aquaculture effluent process of water quality uncertain greenhouse.
EVA material (ethylene-vinyl acetate copolymer) imported China in 1970, was novel environment friendly plastics expanded materials, because it is nontoxic, harmless, soft, waterproof, tool elasticity, was the light industry raw material of the safest, convenient modern, high-quality.EVA has the advantages such as good buffering, antidetonation, heat insulation, moistureproof, resist chemical, all can not cause the distortion of large degree under high temperature, bubble, kneading.In addition, EVA material density is situated between 0.91 to 0.93, can suspend in water.It is not containing heavy metal and biodegradable characteristics, and can not cause secondary pollution to environment, range of application is very wide.
Summary of the invention
The present invention, in order to overcome the deficiency of above-mentioned solid-liquid separating method (precipitation and filter), provides that a kind of structure is simple, floor space is little, convenient management, treatment effect are high, can process the breeding wastewaters such as greenhouse soft-shelled turtle, pig farm and other has high efficient solid and liquid separation device compared with high suspended matter waste water.
The object of the invention is to be achieved through the following technical solutions: the equipment for separating liquid from solid of waste water suspension, comprise pond body, intake pool and solid-liquid separation tank is separated into by perpendicular wall in the body of pond, above intake pool, water inlet is set, communicate with solid-liquid separation tank below intake pool, clear water layer is respectively from top to bottom in solid-liquid separation tank, stop the filtration resistance layer of suspension, diffusion layer and sludge blanket, clear water layer is communicated with delivery port, tool meshed dividing plate is set between clear water layer and filtration resistance layer, suspension meter is provided with in filtration resistance layer, sludge blanket is provided with mud collecting pipe, mud collecting pipe is connected with slush pump.
Above-mentioned filtration resistance layer is the superposed layer being processed into " ten " word shape by hydrophobic inertia EVA material, combining closely between individuality in water.
The equipment for separating liquid from solid of process waste water suspension of the present invention, is applicable to the breeding wastewaters such as greenhouse soft-shelled turtle, pig farm and other have Separation of Solid and Liquid process compared with high suspended matter waste water.
This device intake pool accepts former water, and waste water slowly enters solid-liquid separation tank.
Use procedure is divided into water filtration and cuts off the water collects mud two processes.During water inlet, waste water is entered by intake pool, and when it flows through diffusion layer, the larger particles pollutant such as organism of residual feed in waste water, aquaculture organism excreta and death sinks down into sludge blanket by precipitation.Comparatively granule sedimentation effect is poor, can with current or bubble floating to filtration resistance layer, at filtration resistance layer by the shock with " ten " word shape EVA material, major part is attached to the bubbles burst on particle, comparatively granule is filtered layer obstruct, because in filtration resistance layer, current are close to inactive state, the particle being greater than water density sinks down into sludge blanket under gravity, and then resistance layer and mesh dividing plate are entered clear water layer and overflowed by top delivery port clear water after filtration.In water inlet process, due to intake pressure and dividing plate squeezing action, " ten " font EVA material constantly can rise along with the increase of water inlet, combines closely between final individuality, forms the filter course that porosity is minimum.When suspension (SS) meter monitors waste water SS≤50, filtration resistance layer top, control water inlet by sensor and stop.After water inlet stops, because lower layer of water pressure drop is low, " ten " font EVA material and mud can rapid sedimentations, and mud is collected by underlying collection pipe, is extracted out and discharge by slush pump.Finally realize Separation of Solid and Liquid completely.
The present invention has following advantage:
(1) the hydrophobic inertia EVA material adopted is not novel environment friendly plastics expanded materials, is processed into " ten " word shape, yielding and can be suspended in water.
(2) this EVA material is due to its special " ten " word shape, and under intake pressure and dividing plate squeezing action, can combine closely between individuality and individuality, porosity, has extremely strong filtration.
