Description
Technical field
The invention belongs to Sewage advanced treatment field, particularly relate to a kind of cultural method for the active sludge containing high-concentration hardly-degradable organism, industrial waste water with high ammoniac nitrogen process.
Background technology
Along with industrial expansion, the particularly development of oil, chemical industry, the composition of pollutent is day by day complicated, containing a large amount of organic pollutants in waste water, if be only difficult to Physical or chemical method the requirement reaching improvement, biological process is cheap because of it, and it is convenient to run, and can effectively the advantage such as control polluted articles be widely used.Biological treatment ratio juris is mainly by utilizing the metabolism degradation of organic substances of microorganism, organic pollutant is transformed into harmless gaseous product, product liquid and is rich in organic solid product (microbial population or biological sludge), sewage is purified.Therefore, cultivate and tame out highly active microorganism species, make it give full play to Degradation, can significantly promote biochemical process to the processing power of sewage.
Coking chemical waste water is one more common in trade effluent, produce by the high temperature carbonization of raw coal, gas purification and Chemicals treating process, its complicated component, inorganic and the biodegradable organic compounds containing tens of kinds, belong to high COD, high phenol value, high ammonia-nitrogen wastewater, the especially coking chemical waste water of steel industry, its wastewater flow rate is large, administer difficulty, be the important factor of restriction steel industry Sustainable development always.In recent years, both at home and abroad the research containing high-concentration hardly-degradable organism, industrial waste water with high ammoniac nitrogen process is got more and more, treatment process is varied, and wherein, activated sludge process is containing high-concentration hardly-degradable organism, Biochemical manipulation more widely in industrial waste water with high ammoniac nitrogen process.
Activated sludge process is a kind of method of biological sewage treatment, namely under the condition of artificial oxygenation, continuous mixed culture is carried out to sewage and various microbial population, after forming active sludge, utilize the biological flocculation and precipitation of active sludge, adsorption and oxidation effect, to decompose the organic pollutant removed in sewage, it has, and wastewater treatment capacity is large, efficiency is high, process range is wide, the features such as relative running cost is lower, but require higher, as the pH, temperature, nutrition source dosage, toxic substance concentration, entering organic matter of water concentration, dissolved oxygen etc. of waste water to the condition of water quality of waste water.So before biochemical system unlatching, need to tame mud, waste water quality can be adapted to, reach most degradation ability, and in the process, shorten the culturing sludge time, reduce toxigenic capacity, find best cultural method, biochemical system is put into operation as early as possible and makes standard water discharge significant.
As CN 103708610A discloses a kind of cultural method of Treatment of Coking Effluent active sludge, the treatable waste water COD load of mud that the method is turned out is 2600-2900mg/L, because the coking chemical waste water water yield is large, and water COD is higher, the sludge treatment ability that this method is cultivated is relatively low, and the domestication time is long.Li Xiuyan (tame for the cultivation of Treatment of Coking Effluent by domestic sludge, 32nd volume the 2nd phase, in April, 2010) utilize the dewatered sludge of domestic sewage factory to do bacterial classification, dewatered sludge convenient transportation, but dewatered sludge needs to do process in early stage at domestic sewage factory, and dehydration forms mud cake, also need to add water before input to stir into mud, process is numerous and diverse, and influent quality will be gone to stablize, and the domestication time is longer.
CN 1884134A discloses a kind of two-stage synchronous nitrification denitrification process ammonia nitrogen waste water method, this method filters out the allotrophic nitrobacteria and the aerobic denitrifying bacteria that environment are had to stronger adaptive faculty, adopt allotrophic nitrobacteria and aerobic denitrifying bacteria to build synchronous nitration and denitrification sludge system process nitrogenous effluent, but this method need sodium succinate 4.7g, KNO3, MgSO in sludge for agricultural use process
47H
2the materials such as O trace element solution, culturing process is complicated, and the domestication time is long, and cost can increase in actual large scale culturing.
In sum, there is a lot of problem in active sludge in culturing process, as long in culture cycle, culturing process is numerous and diverse, fluctuation of service, operability are low.Although the method for culture sludge has a lot, the problem such as ubiquity microorganism consumption is large, cost is high, the waste water COD load that bears is lower.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind of bacterial classification wide material sources, cost is lower, the activated sludge culture method that incubation time is short, the activity of activated sludge that the method obtains is high, target elements controls clearly, suitability is strong, can bear the higher COD load of waste water, really achieve trade effluent, especially the advanced treatment of high-concentration hardly-degradable organism, industrial waste water with high ammoniac nitrogen.
