Description
Technical field
The invention belongs to environmental technology field, be specifically related to a kind of Powdered Activated Carbon, nutritive salt and microbial strains throwing device.
Background technology
At present, for advanced treatment of industrial waste water, can adopt the method that Powdered Activated Carbon adsorbs stink, colourity, organic pollutant etc. in the water that adds.Country's pay attention to day by day environmental protection work, the environmental emission standard improves constantly, and Powdered Activated Carbon is used also more and more widely in dirt, wastewater treatment.Powdered Activated Carbon wet type adding equipment generally all has some mixing drums; Mixing drum generally has whipping appts; After Powdered Activated Carbon and water mixed in mixing drum, it was about 8% slurries that Powdered Activated Carbon is configured to concentration, through volume pump mixed solution is dropped in the former water again.Powdered Activated Carbon automatic wet-type adding equipment generally all has a feed bin, and this feed bin is positioned at the upper reaches of whole plant, and its purposes is the storage powder gac.The top of feed bin is typically provided with the opening that communicates with ambient atmosphere, so that the feed bin internal pressure keeps constant, guarantees that Powdered Activated Carbon can successfully join in the feed bin and successfully from feed bin, provides.Because the Powdered Activated Carbon fineness of selecting for use is 150～200 orders; Powdered Activated Carbon can produce a large amount of airborne dusts in the process that adds feed bin; This opening just because of the feed bin top; Make airborne dust run out of feed bin, this not only causes serious dust pollution to surrounding environment, has also caused the waste of Powdered Activated Carbon.So have the dealer to install sack cleaner,, increased complicacy, input cost and the running cost of equipment but effect is not good enough to reduce dust pollution at this pneumostome place.The Powdered Activated Carbon wet type adds two shortcomings: the pollution problem of (1) dust from flying.Powdered Activated Carbon all is packed, and unpacking it feeds intake when pouring the charcoal stock tank into, and entrained air the black powder gac and flown upward, and the chemical feed room dust is filled the air, and causes work under bad environment, and the operator works in this environment for a long time and is prone to suffer from occupational illness.Dust pollution is to restrict its key in application problem for a long time.(2) powdered carbon blockage problem.Domestic Powdered Activated Carbon quality is uneven, and is impure many, in each big water factory application process, the stuck situation of accurate feeding machine taken place repeatedly, serious threat water factory operating safety.
Trade effluent generally will add biochemistry pool in 1: 1 ratio with sewage when carrying out biochemical treatment, and adds nutritive salt.For guaranteeing the mikrobe eubolism; The ratio of carbon in the waste water (C), nitrogen (N), phosphorus (P) generally was controlled at 100: 5: 1; Situation out of proportion according to the complexity of the concrete pollutent biochemical treatment of waste water and carbon (C), nitrogen (N), phosphorus (P) needs in time to replenish the necessary nutrition agent of bacterium, like flour, glucose, microcosmic salt etc.Trade effluent hard to manage BOD often occurs at anaerobism, aerobic system
5Anaerobism, aerobic system must be returned in a large number with settling tank mud in/COD＜0.1, strengthen the amount of adding nutrition agent simultaneously, guarantee BOD
5The activity of anaerobism, aerobic bacteria is recovered in/COD＞0.1, and then recovers the ability of microbiological deterioration pollutent.Most of domestic sewage work becomes bag to pour the sewage pond into nutrition agent with artificial; Nutrition agent is dissolved in the sewage; Squeeze into biochemistry pool with pump; Become organic carbon or waste material at the bottom of having part flour, glucose, potassium primary phosphate, tsp etc. to be deposited to the sewage pond, need to cause very big waste at the bottom of the manual regular cleaning pond.Also have and directly pour nutrition agent into biochemistry pool.There is part nutrition agent sedimentation becoming organic carbon to cause biochemical sludge rotten and then cause biochemical treatment system disorderly.
Ammonia nitrogen is the bigger pollution factor of harm in the water body, and it can cause the eutrophication in river, lake, and water body self-purification ability is weakened.The ammonia nitrogen of polluted-water is often referred to the nitrogen that exists with the ammonia form, and the difficulty of ammonia nitrogen removal is much bigger in the contaminated water body of other organic pollutant relatively.In the prior art, the removal method of ammonia nitrogen mainly contains physics, chemistry and biological method in the contaminated water body.Physics or chemical method comprise air stripping method, break point chlorination, ion exchange adsorption, flocculent precipitation, electroosmose process, catalytic wet air oxidation, liquid-film method etc.These methods generally are used for the pre-treatment of high-concentration ammonia nitrogenous wastewater, and processing cost is very high.It is the effect through certain micro-organisms that biological process is removed ammonia nitrogen, thereby makes the ammonia nitrogen in the contaminated water body finally form the purpose that nitrogen effusion water body reaches purifying treatment.The biological process cost is much lower, and its applicable surface is also wider, like removal of ammonia nitrogen in ammonia nitrogen purifying treatment, sanitary wastewater or the trade effluent of fishery cultivating water body etc.Biological process is removed ammonia nitrogen and is mainly comprised nitrification process and denitrification process.In the nitrification process, ammonia nitrogen is oxidized to nitrate salt or nitrite nitrogen under the aerobic condition under the effect of nitrifier; Denitrification is meant that nitrate salt and nitrite are reduced to the process of gaseous nitrogen.Under anoxia condition, utilize organism as electron donor, denitrifying bacterium is reduced to nitrogen with nitrate salt and nitrite.In these two processes, it is generally acknowledged that the nitrification process is even more important, it is the key that biological process is removed ammonia nitrogen, the difficulty of its completion is also higher relatively.Because most of nitrifiers are chemosynthetic autotroph mikrobes, and compare with the heterotroph mikrobe, the autotrophic microorganism proliferative speed is slow, growing environment is harsh, can't in the growth competition, get the mastery with the heterotroph mikrobe under a lot of conditions.Therefore; When nitrifier content in the water body is low; The environment such as oxygen supply and pH value of only regulating sewage still can't make the breeding of nitrifier self-sow in the short period of time; In way common in the industry is directly in sewage, to throw in the nitrated bacterial classification of cultured high density, contains the active sludge of high density nitrifier like input.The nitrated bacterial classification of these high densitys is to cultivate through special operation to obtain, and has all introduced the cultural method of the nitrated bacterial classification of high density that is used for removing the sewage ammonia nitrogen like Chinese patent ZL02156977.0 and one Chinese patent application 00808700.8.Introduce nitrated bacterial classification by the external world and can guarantee that really the nitrification process successfully carries out in the short period of time; But operational management is very inconvenient; Cost is also higher relatively, and the suitability of this method is not wide in range, just as handling very not suitable for the bigger industrial sewage of quantity discharged.Chinese invention patent application number 200610025171.5 provides a kind of method that adopts sequencing batch active sludge to remove sewage ammonia nitrogen; Means such as oxygen supply through adding a kind of nitrobacteria culture promoter and fit adjustment sewage to sewage and pH value can be built in water body and are fit to nitrobacteria growth breeding environment; Nitrifier is growth and breeding at short notice, removes in the ammonia nitrogen nitrification process need and introduces this technical problem of nitrated bacterial classification by the external world thereby can solve biological process.
