Description
Invention field
The invention of this reality belongs to the biological fermentation technical field of waste water processing, relates to a kind of Xanthan gum waste water treatment process.
Background technology
Since the sixties in 20th century, U.S. Kelco company dropped into suitability for industrialized production with xanthan gum, xanthan gum was used very extensive in fields such as food, oil, agricultural chemicals, feed, daily use chemicals, environmental protection, weaving, makeup.Along with the fast development of oil production industry in recent years, to the demand surge of xanthan gum, China has become the maximum xanthan gum producing country in the whole world.Because xanthan gum is the biological fermentation polysaccharide, will inevitably bring the fermented waste fluid pollution problems, in the xanthan gum waste water, contain a large amount of fermentation pollutents, mainly contain inorganic salt such as part sodium-chlor, SODIUMNITRATE, calcium chloride and a large amount of carbohydrate and organic molecule material such as residual sugar, acetate, pyruvic acid etc., CODcr is more than 4000mg/L.If handle badly, not only pollute the environment, also can waste biological substance wherein, the water resources to China constitutes a threat to simultaneously, will seriously restrict the development of enterprise.
Xanthan gum is the product innovation that begins suitability for industrialized production recent years, because technology is blocked mutually, domestic and international research to the comprehensive utilization of xanthan gum waste water is less, to the comprehensive utilization of xanthan gum waste water, does not up to the present have proven technique.
Summary of the invention
Purpose of the present invention, be in order to overcome the deficiencies in the prior art, and provide a kind of Xanthan gum waste water treatment process, this technical scheme efficient height, have do not run stable, the anti-high loading of mud, effluent index impact, form granule sludge fast, produce advantages such as the natural pond is large-minded, and realized recovery of resources.
In order to address the above problem, technical scheme of the present invention is: xanthan gum waste water is handled through cooling, adjusting mud granule proportion and intensity, acidifying, adjusting pH value, anaerobic biological.Its concrete steps are:
(1) cooling with the dry in the air water tower cooling of xanthan gum waste water through plural serial stage, is cooled to 38 and spends between 43 degree, and winter temperature is lower, and cooling is relatively easy, advances a jar water temperature and is controlled between 38-40 degree; Summer temperature is higher, and the water relative difficult of drying in the air is advanced a jar water temperature and is controlled at 41-43 degree;
(2) regulate mud granule proportion and intensity, warm equalizing tank during the xanthan gum waste water after the cooling is imported, described middle temperature is 38-43 ℃, adds liquid lime to regulate mud granule proportion 1.05-1.2;
(3) acidifying joins in the acidification pool in the xanthan gum waste water, is converted into small molecular organic acid class material through acidication, and the time in the acidization is 5-8 hour; Xanthan gum waste water belongs to food wastewater, is subjected to self very easily acidifying of water quality reason, does not need additionally to add the acidifying bacterium in the water, and there are a large amount of acidifying bacterium in equalizing tank and acidification pool, anaerobic jar bottom section.The soluble large molecule organism is converted into lipid acid, alcohols, lactic acid, ammonia, hydrogen sulfide etc., and the pH value just can reduce to 4.5 from 6.0.
(4) regulate the pH value, the basicity employing adding liquid caustic soda of the xanthan gum waste water after the acidifying, the method for liquid lime are adjusted, reach the required pH value of anaerobic biological processing and be 6.0-6.5;
(5) the xanthan gum waste water in the step (4) is imported anaerobic reactor and carry out the anaerobic biological processing, the temperature in the anaerobic jar is 35-38 ℃, and duration of the reaction is 11-13 hour, and pH value is 6.5-7.5.
Anaerobic biological treatment is the chemistry of micro-organisms process of a complexity, relies on the bacterium of three big main monoids, i.e. the combined action of acidication bacterium, product hydrogen acetogen and methanogen is finished.
Required bacterium is promptly in content of the present invention: the acidication bacterium, produce that hydrogen acetogen rate of propagation is fast, the domestication time is short, and do not need other interpolation.Methanogen (being anaerobic grain sludge) rate of propagation is slow, the domestication time is long, needs extra the interpolation during startup, generally starts addition at the 30%(volumetric quantity) more than.
(1), the three phases of anaerobic digestion
Studies show that methanogen can only utilize some simple organics such as formic acid, acetate, methyl alcohol, methyl amine and H
2 / CO
2 Deng, contain above lipid acid of two carbon and the alcohols beyond the methyl alcohol and can not utilize.Therefore, the anaerobic process must be passed through with the next stage:
Fs: hydrolysis, souring stage
Subordinate phase: produce hydrogen and produce the acetate stage
Phase III: produce methane phase
(2), the major microorganisms in each stage
A. acidication stage
Major function:
Hydrolysis: under the effect of extracellular enzyme, insoluble hydrolysis of organic matter is become dissolved organic matter;
Acidifying: the soluble large molecule organism is converted into lipid acid, alcohols, lactic acid, ammonia, hydrogen sulfide etc.;
Predominantly bacteria:
Fusobacterium, Bacteroides, Butyrivibrio, Bifidobacterium etc.;
B. produce hydrogen and produce the acetate stage
Major function: various higher fatty acid and oxidation of alcohols are decomposed into acetate

Predominantly bacteria:
Syntrophism zygosaccharomyces, syntrophism Bacillaceae, fusobacterium, dark Bacillaceae etc.;
This stage acidication back pH value is fully reduced to 4.0-4.5 from 6.0 of water inlet.
C. produce methane phase
Major function: the product acetate and the H that will produce the hydrogen acetogen
2 / CO
2 , formic acid, methyl alcohol etc. is converted into CH

In the application of anaerobic treatment of waste water, owing to producing acid and producing methane and in same structures, carry out mostly,, often keep the interior pH value of reactor at 6.5-7.5 so, avoid too much acid accumulation in order to keep balance, preferred PH is in the scope of 6.8-7.2.For guaranteeing that this stage can carry out more smoothly, water outlet pH value generally needs be adjusted to 6.8 with liquid lime or liquid caustic soda---between 7.2, be beneficial to the smooth propagation and the metabolism of methanogen.
The principle of anaerobic treatment is to utilize anaerobion in suitable temperature, the process of degradation of contaminant under the conditions such as potential of hydrogen.Reactor is divided into, cloth pool, biochemical reaction zone, settlement separate district, exhalant region etc.Technology is, pollutent enters with anaerobion in the cloth pool and fully contacts absorption, in the current uphill process, fully decompose digestion, entering settlement separate district back microorganism separates with aqueous vapor, microorganism returns the cloth pool and biochemical zone repeats degraded, flow out from exhalant region after the water treatment, gas is drawn by pipeline and is delivered to boiler combustion.Form the successive treating processes.Microorganism adds about 30 percent of reactor volume in the reactor at the beginning of starting.Along with the raising normal dimensions of processing power is held in about 50 percent.Because microorganism is in constantly breeding growth, redundance can be sold.
The invention has the beneficial effects as follows:Adopt this its efficient height of art breading xanthan gum waste water, technology is simple, easy to operate, have do not run stable, the anti-high loading of mud, effluent index impact, form granule sludge fast, produce advantages such as the natural pond is large-minded, and realized recovery of resources.Processing efficiency can improve 20% the processing rate of going than traditional anaerobic treatment process, and operating load can improve more than 80%.
