Description
Technical field
The invention belongs to animal husbandry field wastewater processing technology, particularly relate to the plunger type of a kind of pretreatment livestock breeding wastewater
Screen filtration device.
Background technology
Solid-liquid separation technique refers to separate the solid constituent in pollutant and liquid solution.According to solid-liquid separation mistake
The motive force of journey, can be divided into three major types: (1) settling methods, it is to utilize action of gravity to make solid by solid-liquid separating method
Grain sedimentation thus the method that reaches solid-liquid separation, industrial conventional equipment has Sedimentation tank, various thickeners etc.；(2) filter
Method, it is to utilize filtered driving force to borrow the method that filter medium realizes solid-liquid separation, is the method for the most frequently used acquisition clear liquid, conventional
Equipment is various types of filter；(3) centrifugal separation, it utilizes centrifugal action to make solid particles sediment and filtration
Method, under strong centrifugal action, the solid particle rapid subsidence that proportion is bigger forms mud cake on rotating cylinder inwall, isolated
Moisture forms liquid level, the speed discrepancy between helical form carrier and rotating cylinder in rotating cylinder on mud cake surface, makes mud cake by spiral
Carrier blade pinches is discharged at the conical outlet of rotating cylinder, isolated moisture then from the cylindrical end of rotating cylinder through overflow weir flow
Going out, the most frequently used equipment has sedimentation centrifuge and filter centrifugal etc..
Containing substantial amounts of excrement slag in breeding wastewater, solid content is the highest, disturbs the normal process of this kind of waste water, place up to standard always
Reason difficulty is big.At present, many plants have employed simple Washdown type granular membrane filtration treatment, and excrement slag and water separating effect are not
Substantially, manual operation intensity simultaneously is big；Part plant have employed belt filter press filtration treatment, but belt filter press feeds water
Pump lift is high, energy consumption is high, causes operating cost can not to be in any more, and enterprise is difficult to bear；Ye You plant uses coagulating sedimentation technology
Pretreatment breeding wastewater, solid-liquid separation effect is obvious, but dosing is very big, not only increases considerably operating cost, and
And add waste residue generation amount, improve solidification disposal of waste cost.Therefore, in breeding wastewater, the economical and effective of excrement slag separates is one
It is worth the problem of research.
Granular membrane is a kind of simple and effective filter plant, and cost is relatively cheap, at home and abroad industrial wastewater, city
City's sanitary wastewater and agricultural irrigation systems use extensively.The filtration mechanism of granular membrane is exactly the hole utilizing screen cloth,
It is retained down more than the impurity particle of pore-size, it is thus achieved that the fluid product of needs.Its Main Function is to filter out in waste water
Organic suspended matter, solid debris, the dirt such as silt.Granular membrane is in actual motion, and be easiest to generation is exactly screen cloth
Blocking, such as, when in waste water, organic suspended matter content is slightly higher, especially when pressure is bigger, substantial amounts of organic dirt can glue
On screen cloth and get in sieve screen apertures, causing filtration system water route smooth and blocking, therefore, screen cloth needs often to clean.
How to overcome conventional screen net filtration technology blockage problem and reduce the cleaning frequency, exploring more efficient filtering technique,
Become the starting point proposing the present invention.
Coagulation technology is to use coagulant to remove larger molecular organics and the common technology of colloidal solid thing in waste water, and it is made
With being to change the surface characteristic of colloidal solid by adding chemical agent, make scattered colloidal solid assemble and form bulky grain
Thing.The series of problems caused to solve screen filtration to block, the present invention develops one and changes waste water by coagulated agent
Middle particulate matter performance also makes its coacervating large particle thing, thus reduces Organic substance or small particle sticks on screen cloth, thus has
Effect solves screen filtration blockage problem.
Summary of the invention
For solving above-mentioned technical problem, it is an object of the invention to provide a kind of screen cloth will not block, without clean screen cloth and
