Description
Technical field
The invention belongs to sewage treatment fields, and in particular to arrive a kind of formula of high-concentration chemical industry sewage composite bacteria agent.
Background technology
The environmental protection industry in China is started late, but is quickly grown, at present in all kinds of waste water treatment process of sewage treatment field
Technology and device fabrication are quickly propelling, and all trades and professions have been built up large number of throughout the country, and in large scale is useless
Sewage treatment plant (stands), achieves good environmental benefit and social benefit.Meanwhile the environmental protection industry in China also face it is many tight
High problem is spent a large amount of manpower and materials in the introducing process of green technology and is changed in process modification, equipment due to eager for instant success and quick profits
In the optimization of type and microorganism growing environment, but to the microorganism that biochemical treatment plays a decisive role, few people make inquiries unexpectedly,
So that the numerous sewage treatment process of the item such as AO methods, AAO methods, AOAO methods, SBR methods, CASS methods, CAST methods is come on stage one after another,
The patent of various fillers and manufacturer are too numerous to mention, but still accounting for significant percentage of sewage treatment plant (station) at present can not be just
Often operation, especially in some high-concentration chemical industry sewage process fields, manufacturing enterprise spends huge sums the sewage treatment facility of construction, greatly
More operating conditions are not good enough, and not only operating cost is high, but also is unable to qualified discharge, still to be paid to local environmental protection administration exceeded
Discharge expense, some are even forced to stop production.
The trade effluent complicated component of high concentration, including alkyl halide hydro carbons, olefines, alicyclic hydrocarbon type, heteroaromatic hydro carbons,
Halogeno-benzene alkanes, tetrabromobisphenol class, nitrobenzene, furans, pyridine, sulfate and various artificial synthesized organic pollutions
Enter environment with the waste water or solid waste of plant emissions, due to the strange property of the complexity and biology of these substances this body structures,
The microorganism of traditional wastewater treatment method activated sludge culture cannot effectively remove these pollutants,
These substances accumulate in the environment for a long time, and very big pollution is caused to the ecological environment that we depend on for existence, strong to the body and mind of the mankind
Health brings very big harm.Quite a few industrial pollution enterprise of China, which would rather be punished, is also unwilling that waste water is administered in investment, even if having
Sewage-treatment plant operation is also abnormal.
Therefore, develop that biomass is more in a kind of unit volume and biofacies is abundant, bioactivity is high, rapid decomposable organic
Substance improves the complex microbial inoculum of COD, BOD, TOC, ammonia nitrogen and certain specific hard-degraded substance removal rate to current
Sewage disposal technology is extremely urgent.
Invention content
The technical problem to be solved by the present invention is to overcome the existing defects, provides a kind of high-concentration chemical industry sewage compound bacteria
Agent, the composite bacteria agent are mixed by the raw material bacterium of following parts by weight：
Bacillus cercus 180~220,150~160 parts of Bacillus circulans, 75~85 parts of acetyl Exiguobacterium sp, condensation

140 parts, 180~230 parts of Rhodococcus sp, 20~30 parts of Lactobacillus brevis, 50~65 parts of Paracoccus denitrificans, 95~112 parts of Alcaligenes faecalis,
110~125 parts of pseudomonas putida, 100~130 parts of clostridium perfringen, 200~250 parts of thermophilic salt Halomonas, brewer's yeast
280~320 parts, 140~160 parts of lactobacillus fermenti.
Further, which is mixed by the raw material bacterium of following parts by weight：200 parts of Bacillus cercus, ring
155 parts of shape bacillus, 80 parts of acetyl Exiguobacterium sp, 100 parts of bacillus coagulans, 160 parts of pseudomonas aeruginosa, M. luteus
23 parts of bacterium, 130 parts of thiobacillus thiooxidant, 200 parts of thermophilic salt alkali bacillus, 100 parts of halo micrococcus luteus, 30 parts of photobacterium phosphoreum, short breast
25 parts of bacillus, 60 parts of Paracoccus denitrificans, 103 parts of Alcaligenes faecalis, 120 parts of pseudomonas putida, 120 parts of clostridium perfringen, thermophilic salt
230 parts of Halomonas, 300 parts of brewer's yeast, 150 parts of lactobacillus fermenti.
Strain of the present invention can be from China Committee for Culture Collection of Microorganisms's common micro-organisms center
(CGMCC), China typical culture collection center and American Type Culture collection warehousing (ATCC), Chinese agriculture microbial bacteria
Kind preservation administrative center (ACCC) is commercially available.
The existence form of the composite bacteria agent of the present invention is preferably freeze-dried powder, microbial inoculum or microbial inoculum and solid
The mixture of auxiliary material.
The existence form of the microbial inoculum be freeze-dried powder when, preparation method include Bacillus cercus, Bacillus circulans,

Zymotic fluid is prepared, after being mixed according to mass ratio, freeze-dried powder is made by this field conventional method.
A method of utilizing the high-concentration chemical industry sewage composite bacteria agent treated sewage of the present invention, which is characterized in that including
Following steps：
1), the polyurethane block filler of a diameter of 0.5~3cm is placed as composite bacteria agent in the bottom of pond of sewage reactor
Carrier；
2) 5L COD, are added in sewage reactor in the treatment sewage of 800~1000mg/L diluted, Portugal is added
Culture solution is made in grape 150~160g of sugar, 6~8g of dipotassium hydrogen phosphate, 6~8g of epsom salt, 40~60g of wheat bran, stirring and dissolving；
The pH of culture solution is adjusted to 7~7.5；
3) 50~80g of composite bacteria agent, is added into culture solution；It is uniformly mixed；
4), water temperature control is stirred 3~5 times daily at 30~35 DEG C, every time ventilative half an hour；
5) removal rate of the COD of sewage, ammonia nitrogen in reactor, is measured daily；When COD of sewage drops to 300mg/L or less
Afterwards, the concentration and salinity of influent COD are stepped up, but total salt concentration need to be controlled and be not more than 40000mg/L, when by 5~10 days
After cycle, start to continue through not diluted treatment sewage.
The beneficial effects of the invention are as follows：A dosing method can be used with composite flora in the sewage disposal of the present invention, operates
Simplicity is conducive to production, can quickly form dominant microflora；Reasonable compatibility between each strain in formula, symbiosis is coordinated, mutually not short of money
Anti-, the survival rate of microbial inoculum is high.Method using the microbial inoculum treated sewage of the formula is simple and practicable, to macromolecular, difficult to degrade, toxic
Harmful substance such as phenols, arene and ammonia nitrogen, phosphorus, high-sulfate etc. have unique treatment effect, COD removal rates may be up to
94.17%, have very high Treatment Stability and utilization rate, be suitable for high-concentration chemical industry sewage handle, can be improved processing water and
Water quality treatment reduces operating cost, promotes qualified discharge.
