Description
Technical field
The invention belongs to filtrate technical field, be specifically related to hydrophilic oleophobic filtrate and preparation method thereof.
Background technology
Fiber-ball filter media is formed by filament ligation.Fibrous nodules can remove the suspension in water effectively, and has obvious removal effect to the organic matter in water, colloid, iron, manganese etc.Fiber-ball filter media is since the eighties puts goods on the market, and existing applicating history for many years at home, it is large with specific area, porosity is high, and holding filth capacity is large, drag losses is little, filtering velocity is high, effluent quality is good and be subject to the recommendation of water treatment insider.
Fibrous nodules is widely used in recirculated water bypath filter, Living Water advanced treating, boiler feedwater process, counter-infiltration prefilter, and reusing sewage filters.Fibrous nodules be applicable to oil-contaminated water of oil field re-injection thick, in, fine filtering and oil field, sewage from oil refinery outer row's process; Fibrous nodules is applicable to iron and steel, thermoelectricity, shipbuilding, papermaking, chemical industry, weaving, the recycling filtration treatment of the various industrial recirculated water such as swimming pool and domestic water and waste water thereof.Fiber ball filter is applicable to the water treatments such as pure water, seawater, brackish water desalination and central water supply engineering, city sewage treatment works.
Fiber ball filter utilizes the feature of fibrous nodules can various impurity in filtered water, reach the object of clean water, but in time containing a large amount of greasy dirts in water, common fiber-ball filter media but can not play desirable effect, because greasy dirt is easily adsorbed in general fibre ball filtering material surface, be finally bonded together, miss one's aim.Although in the process of oil-polluted water, fiber-ball filter media has good oil removing ability.But due to the lipophile that fiber-ball filter media surface is extremely strong, can not rinse well after making its adsorbed oil, hinder fiber-ball filter media applying in filtering oily sewage process.So, there is modified fibrous globule filtering material.Carrying out hydrophilic oleophobic modification to fiber ball surface can head it off.When modified fiber-ball filter media contacts with oil-polluted water, first contact with hydrone, form the diaphragm of one deck water on fiber-ball filter media surface, be easy to during backwash be rinsed by water.
String (plantfibre) is a kind of sclerenchyma be extensively distributed in seed plant.Its cell is elongated, and two ends are sharp-pointed, have thicker secondary wall, wall often has simple pit, the protoplast of generally not living time ripe.String is main in plant plays mechanical supporting function.In the plant stem of ramie, the bast fibre bundle that tool is flourishing especially, the various textile of available system.These fibers do not have or little lignifying, claim soft fibre.As-spun fibre just occurred before organ extends, and cell is around still when division, and they can also continue suitable length of extending.The bast fiber of ramie can continue to extend some months, and the length finally increased is original 4,50,000 times, the longlyest reaches 55 centimetres.The elongation of this cell, except increasing (symplastic growth) together with peripheral cell; Cellular apical can extend into the growth (intyrusive) between peripheral cell in addition.After ramie harl stops elongation, when there is the deposition of secondary wall, the base portion of fiber may also have thick secondary wall.But top still has the content of life and thin cell membrane, therefore, cellular apical can also continue to extend.
The modified fibrous globule filtering material adding plant component can play the important and pivotal role in filtration oil-containing water quality, has also played the effect of the efficient non-secondary pollution of general fibre ball filtering material simultaneously.
