Description
Technical field
The present invention relates to a kind of microbial membrane carrier.
Background technology
At present, sanitary sewage, trade effluent generally being adopted bioremediation, is to add in biochemistry pool and the carrier of the approaching bio-carrier of water proportion as attached growth of microorganisms and use wider biological moving bed technology.But the unmodified bio-carrier of domestic production at present mainly makes with the macromolecular material straight forming.Its weak point is that surface hydrophilicity is poor, and microbial film comes off easily, ammonia nitrogen removal frank is low, make water treatment often break down and handle after the water quality instability.
Summary of the invention
The object of the present invention is to provide a kind of wetting ability that can strengthen carrier surface and to organism adsorption in the water and can improve the modified microbial membrane carrier of bio-carrier to nitrated ability of ammonia nitrogen and clearance.
The basic material of carrier of the present invention is a high density polyethylene(HDPE).The modified feedstock of carrier of the present invention has two kinds of i.e. a material and No. two material.
Composition, consumption and the method for making of a material are as follows:
Composition: waste stone dust, coke powder, slag powders, iron powder (their fineness is not less than 200 orders).
Consumption: waste stone dust 18-19.6 part, coke powder 1.5-1.8 part, slag powders 1.14-2 part, iron powder 0.36-0.6 part.
Method for making: above-mentioned raw materials is placed the mixing tank mixing, add 51-54 part high density polyethylene(HDPE) again and mix, send into the tablets press high temperature process and become particulate matter.
Composition, consumption and the method for making of No. two material are as follows:
Composition: slag powders, talcum powder, iron powder (their fineness is not less than 200 orders)
Consumption: slag powders 11.35-12.75 part, talcum powder 14-15 part, iron powder 2.15-2.25 part.
Method for making: identical with a material method for making, wherein high density polyethylene(HDPE) is 45-47.5 part.
The preparation method of modified microbial membrane carrier:
1. take by weighing raw material by following weight ratio: high density polyethylene(HDPE): a material: No. two material=25: 3-5: 3.5-5.5.
2. extrude by forcing machine high temperature:
1. forcing machine is heated up, fuselage (feeding section, compression section, homogenizing zone) temperature reaches 135 ℃.Head (screen plate place, head 1, head 2, mouthful mould place) temperature reaches 130 ℃.
2. above-mentioned raw material through mixing is sent in the extruder barrel, along with the rotation raw material of extruder screw is forced to push to heading.What extrude from the extrusion die mouth is the product with definite shape, moulds, cuts typing surely and just can obtain the right cylinder that there is the cross resting support grey black inside through sizing, cooling.Preferably the cross section of cylinder is a profile of tooth.Its density≤0.98kg/L.
The present invention has following advantage compared to existing technology:
1. microbial membrane carrier wet density of the present invention approaches water, and the preceding 0.96～0.98kg/L of biofilm approximates 1kg/L after the biofilm.
2. surface hydrophilicity of the present invention is strong, and microorganic adhesion is good, biofilm is easy, difficult drop-off, the no sludge blockage phenomenon of long-time running, and the biomembrane activity height, the film minimal thickness is only at 10～200 μ m.
3. the present invention contains the enhancing ingredients to biological enzyme, promote the katalysis of biological enzyme, improved its clearance significantly to nitrogen phosphorus, with the sanitary sewage is example, the ammonia clearance is 98～100%, nitrogen removal efficiency is 80～85%, and tp removal rate is 70～75%, and COD, BOD clearance reach more than 90%.
4. the microorganism on the microbe carrier forms long food chain, so the sludge settling performance is good, the mud generation is few, lacks 40～80% than original activated sludge process generation, and processing efficiency has improved 30～50%, and working cost reduces by 30%.
5. improved rigidity and toughness, be work-ing life 50 years, dropped in the reaction tank and need not change and manual maintenance.
6. specific surface area of the present invention is big, organism in the water is produced adsorption, it is poor to the organic concentration in the water to form the biofilm carrier surface, so the microorganism near filling surface is active strong because nutrient concentration is high, otherwise the low and poor activity of concentration then, thereby the microorganism of filling surface grows from inside to outside.
