Description
Technical field：
The invention belongs to field of Environment Protection, are related to a kind of mobility bio-carrier, specifically a kind of to contain high hole diatom
Mobility bio-carrier.
Background technology：
The carrier that China uses at present can substantially be divided into 3 major classes：The first kind is fixed carrier of shaping, mainly honeycomb
Class carrier；Second class is suspension type carrier such as flexible carrier, semi-soft carrier, elastic stereo carrier, combined carrier etc.；3rd
Class is stacked, floated carrier, such as Pall ring, cascade ring, hollow ball, suspended particles.But this field of flowable carrier
Still belong to blank.
The content of the invention:
For above-mentioned technical problem of the prior art, the present invention provides a kind of mobility biologies containing high hole diatom
Carrier, it is biochemical that this mobility bio-carrier containing high hole diatom will solve traditional activated sludge process in the prior art
The technical issues of system operation is unstable, COD removal rates are not high, back segment treatment operating costs are high.
The present invention provides a kind of mobility bio-carriers containing high hole diatom, are made of high hole diatom and adjuvant,
The adjuvant is poly aluminium chloride or aluminium polychloride, and the mass ratio of the high hole diatom and adjuvant is 65-75:
25-35。
Further, the high hole diatom, the mass ratio of aluminium polychloride are 70:30.
Further, the index of the high hole diatom is as follows：
Area >=63% of small ring algae；
SiO2Mass percentage content >=59.5%；
Noncrystal SiO2Mass percentage content >=42%；
Porosity >=56%；
Average grain diameter μm≤20%；
Al2O3Mass percentage content≤15%；
Al2Cln(OH)6‐nMass percentage content≤30%；
Fe2O3Mass percentage content≤10%；
Mass percentage content≤1% of GaO；
Mass percentage content≤3% of MgO；
Loss on ignition≤10%；
Mass percentage content≤10% of moisture；
PH value is 6.0-8.0；
Specific surface area is 19.0-65.0m2/g。
High hole diatom as pure natural carrier material, have outstanding mobility, not soluble in water, larger specific surface area and
There can be the innate advantage as flowable carrier with activated sludge perfect adaptation.
The characteristics of high hole diatom is as mobility bio-carrier and advantage：
1st, high hole diatom mobility bio-carrier is nontoxic, surface band imbalance current potential, have absorption, coagulation-flocculation,
It the effects that deodorization, decoloration, with reference to traditional ecological environmental protection and restoration harness technology, effectively, thoroughly can solve to give birth to
State problem of environmental pollution, treatment cost is relatively low, and to environment non-secondary pollution, the residential blocks waste water control such as small towns, community in urban areas can
Build into landscape water；
2nd, each carrier in mobility bio-carrier has a hole more than 2000, and every gram of inorganic agent has 30m2Specific surface
Product, there is superpower adsorption effect, with reference to the nanometer micropore of carrier, can form stability and high efficiency as bio-carrier and activated sludge
Zoogloea, when high hole diatom reaches 1% concentration in activated sludge, every cubic metre up to 300,000 m2Specific surface area, with high hole silicon
Algae makees bio-carrier, and microorganism breeds (each pollutant in high hole diatom adsorbed water body on the huge surface area of diatom
Matter), greatly improve treatment effect.
3rd, after use, the dosage of back segment chemical agent is reduced, dehydration property is good, can reduce the sludge quantity of 20%-50%；
4th, more stable more effective for the inorganic agent of bio-cooperation than traditional activated carbon etc., operating cost is less expensive,
It is basically unchanged or even can reduce using the overall operation cost of rear sewage plant；
5th, the present invention also have the advantage that for：Processing cost is low, is 50% of traditional handicraft or so, and high treating effect goes out
Water indices reach GB18918-2002 level-ones A marks；Floor space is small, is the 30%-50% of other techniques, municipal wastewater
Landscape water outlet can be built into and be placed in community etc.；Sludge quantity is few, compared to the sludge quantity that traditional handicraft reduces 20-50%.
The present invention is compared with prior art, and technological progress is significant.The large specific surface area for the diatom that the present invention uses,
Porosity is high, has very strong suction-operated, then the effect for passing through adjuvant so that the pollutant adsorbed on diatom flocculates simultaneously
It precipitates.This mobility bio-carrier containing high hole diatom of the present invention is a kind of pure natural carrier, can be dirty with activity
Mud perfect adaptation forms zoogloea.The biological with high hole diatom mobility as main component of the present invention is added in sewage disposal
Carrier plays absorption, flocculated effect in sewage, and is combined with the microbial in biological tank, microorganism and pollution
Object is adsorbed together on diatom surface, plays the role of bio-carrier, greatly promotes treatment effeciency, can handle various trade effluents
And sanitary sewage, and high treating effect, it is at low cost, take up little area, sludge quantity is reduced, fundamentally treated sewage.
