Abstract
The invention relates to method for processing wastewater produced in a food fermentation process by using a packed bed bioreactor through the combined action of root fungi and lactic acid bacteria, in particular to a novel method for producing high-concentration organic acid by processing wastewater in a food fermentation industry. According to the method, grains are processed into powder and then made into pills together with the root fungi and the lactic acid bacteria, after drying, the pills are filled into the packed bed bioreactor, the wastewater in the food fermentation industry is pumped into the bioreactor, COD in the wastewater is 200-1000 mg COD/L, total nitrogen concentration is 0.1-0.5%, and the initial pH is 6-7. The temperature in the bioreactor is controlled at 30-40 DEG C for performing processing for 5-7 days to stably produce organic acid, COD and total nitrogen concentration in wastewater can be remarkably reduced, and pigment substances in the wastewater can be thoroughly removed.
Description
Technical field
The present invention relates to a kind of bio-carrier and process the novel method of food fermentation industry waste water, particularly relate to and a kind of food fermentation industry high organic waste water being processed by packed bed, utilize organism in waste water to produce the novel method that organic acid " is turned waste into wealth ".
Background technology
Food fermentation industry waste water refers to by grain and comprises that grain by-product is that raw material passes through the waste water discharged after microorganism fermentative production product.In recent years, the food fermentation industry is the monosodium glutamate industry for example, the soy sauce industry, the beer industry, the industries such as Yoghourt industry develop rapidly, and the waste water that these industries are discharged has polluted environment greatly, and consumed a large amount of energy and water resources, also restricted conversely the development of food fermentation industry.China is monosodium glutamate the biggest in the world and beer production state at present, and one ton of beer of every product is on average discharged approximately 15 tons of waste water, and the waste water that annual production beer discharges is more than 500,000,000 tons, and the waste water that annual production monosodium glutamate is discharged reaches more than 400,000,000 tons.This type of waste water has that colourity is high, high organic, complicated component, processes the characteristics such as difficult, seriously affects China's water resource environment and health of human body.
Packed bed reactor claims again fixed-bed reactor.By immobilized enzyme, immobilized cell etc. are filled in reactor, make stable post bed, then pass into substrate solution, under certain reaction conditions, realize catalyzed reaction, with certain flow velocity, collect the conversion fluid of output.Packed bed has high-level efficiency, easy to operate, advantages of simple structure and simple, is the most general reactor of application in current industrial production and research.Utilize the packed bed bioreactor sewage treatment to obtain greater advance, packed bed can be applicable to papermaking wastewater, dyeing and printing sewage, the processing such as sewage from oil refinery.The organic substance that contains high density in the waste water that the food fermentation industry produces, as protein, amino acid, carbohydrate, lipid material etc., also possesses higher BOD, the suspended solid of COD and higher concentration simultaneously; And the coloring matter that often contains higher concentration, as gourmet powder waste water, the ubiquity caramel colorants such as sauce waste water, beer waste water.Contain in addition higher salinity and extreme pH in most of food fermentation industry waste water, cause the numerous food product fermentation waste water to be unsuitable for directly adopting biological process to process.In special reactor, processed food fermentation industry waste water by fixation of microbe, can be realized the microbiological deterioration to high gravity fermentation waste water.Therefore, the setting by appropriate microorganism and packed bed bio-reactor, can realize the comprehensive treating process to food fermentation industry waste water fully, can obtain organic acid simultaneously, as acetic acid, the materials such as citric acid, there is important economy, society, the particularly value of environmental protection.
Summary of the invention
The object of the present invention is to provide a kind of food fermentation industry waste water that utilizes to produce the organic acid novel method, simultaneously by rhizopus, milk-acid bacteria is fixed into ball, by packed bed bio-reactor mode, dispose of sewage, and the output organic acid.
Technical scheme of the present invention is mainly microorganism rhizopus and milk-acid bacteria.
The preparation of bio-carrier and sewage water treatment method.
At first large class grain is made to meal, then meal is mixed by weight 1:1 with rice straw powder, then add water, rhizopus and milk-acid bacteria to mix, this material is placed to flat board, temperature is controlled at 25-30 ℃, treats rhizopus and lactobacter growth 24 h.Again mixture is kneaded into to the little ball that diameter is 4-10 cm, and air-dry in air dryer.This bacterium ball is put into to packed bed and carry out sewage disposal, the temperature of packed bed is controlled at 25-35 ℃, and the treatment time is 5-7 days.
Embodiment:
Below row for two example two, are further illustrated the present invention:
Embodiment 1
First, by 5 kg sticky rice flours, 5 kg rice straw powders mix; 1 % inoculation rhizopus and milk-acid bacteria by the ground rice amount enters in powder mix again, then adds water and mix; This material is added to flat board, and temperature is controlled at 25 ℃, treats rhizopus and lactobacter growth 24 h.The bacterium powder of having grown is kneaded into to the piller that diameter is 6-8 cm.The bacterium ball is air-dry and put into packed bed and carry out sewage disposal, and the temperature of packed bed is controlled at 30-35 ℃.Pump into sauce waste water, process 7 days.Sauce waste water COD clearance rate is 85 %, and caramel colorant removing degree is 99 %, and acidity reaches 6 gL

Embodiment 2
First, by 5 kg rice meals, 5 kg rice straw powders mix; 1 % inoculation rhizopus and milk-acid bacteria by the ground rice amount enters in powder mix again, then adds water and mix; This material is added to flat board, and temperature is controlled at 30 ℃, treats rhizopus and lactobacter growth 24 h.The bacterium powder of having grown is kneaded into to the small muddy pill that diameter is 3-5 cm.The bacterium ball is air-dry and put into packed bed and carry out sewage disposal, and the temperature of packed bed is controlled at 25-30 ℃.Pump into beer waste water, process 6 days, beer waste water COD clearance rate is 80 %, and acidity reaches 8.5 gL
