Abstract
The invention discloses a winery sewage treatment method. The technical scheme is that the winery sewage treatment method comprises anaerobic treatment, aeration and activated carbon adsorption. According to the winery sewage treatment method, heat energy of sewage is recycled in the treatment process, and generated hot water can be used for winery staff. The pH is adjusted with acetic acid, not only is the pH changed, but also the content of acetic acid in sewage can be increased, and the amount of biogas generated in the follow-up anaerobic treatment can be increased. Generated biogas can be used for dinner cooking and lighting for staff, and plenty of coal, natural gas and electricity are saved. Liquor-making raw material residue filtered out can serve as feed for livestock, nutrient substances are easy to absorb and utilize, corn and wheat are saved, and farmer's costs are lowered. A non-woven fabric serves as a biofilm and is low in cost and long in service life and greatly reduces cost. The ideas of energy saving and environmental protection are embodied in the whole sewage treatment process, and the sustainable development view is achieved.
Description
Technical field
The present invention relates to a kind of sewage water treatment method, particularly relate to a kind of brewery sewage water treatment method.
Background technology
Along with developing rapidly of China's wine-making industry, the sewage of brewery's discharge also gets more and more; Alcohol industry is the important basic material industry of national economy, alcohol is widely used in the fields such as chemical industry, food, daily use chemicals, medical and health, be again wine base, digestion agent, solvent, washing composition and tensio-active agent, the production of alcohol is also along with the discharge of sewage simultaneously.
Brewery's sewage mainly from the alcohol grain of discharging after distillation fermenting-ripening wine with dregs, the washing water of production unit, wash-down water, and boiling, saccharification, fermentation, distil process water coolant etc.Brewery's sewage is the organic sewage of high density, high-temperature, high suspended matter, and the waste residue in sewage contains the fermentation raw material after pulverizing, and this kind of material is insoluble COD in sewage; Mierocrystalline cellulose in raw material and hemicellulose are polysaccharose substances, can not become saccharomycetic carbon source and be utilized, remain in sewage, show as solvability COD in zymamsis; Inorganic ash content is sediment contamination mainly.These materials add the difficulty of sewage disposal.In addition in brewery's production waste because of containing a large amount of grain, block suspended substance, homogeneity is very poor, and it is the important factor causing this type of sewage oxygen consumption.
Summary of the invention
The object of the invention is to solve the problem, providing a kind of brewery sewage water treatment method.
A kind of brewery sewage water treatment method, technical scheme comprises the following steps:
(1) lower the temperature through prolong during brewery's sewage discharge, the hot water in prolong can for staff quarters;
(2) sewage after cooling is concentrated in collecting tank, regulates pH to 6.5 ~ 7.5;
(3) by regulate after sewage discharge to methane-generating pit, carry out anaerobically fermenting;
(4) biogas of generation be used for the illumination of brewery's staff quarters and cook;
(5) from methane-generating pit discharge effluent stream to filtering basin, impurity is filtered;
(6) effluent stream after filtering, to aeration tank, carries out aerobic treatment;
(7) sewage after aerobic treatment adsorbs through gac, flows out after filtering.
Described step 2) adjustment of pH regulates with the acetic acid of 5mol/L or the sodium hydroxide of 5mol/L.
Described step 5) is filtered sewage, uses stainless 10 orders, 30 orders and 60 order filtering nets to filter respectively at the water-in of filtering basin, centre and water outlet, using the feed as livestock after filter residue and drying is pulverized.
The aeration tank of described step 6), in it, microorganic adhesion is on non-woven fabrics, and non-woven fabrics is industrial nonwoven cloth, and composition is terylene, and membrane flux is 10 ~ 12L/ (m
2h), the dissolved oxygen amount of aeration tank is 3mg/L.
Beneficial effect of the present invention is: brewery provided by the invention sewage water treatment method, recycles in treating processes to the heat energy of sewage, and the hot water of generation can for brewery worker; Use second acid for adjusting pH, can pH be changed, the acetic acid content in sewage can be increased again, the methane quantity produced in follow-up anaerobic treatment process can be increased; The biogas produced can be cooked for worker and throw light on, and has saved the use of a large amount of coal, Sweet natural gas and electricity; The liquor-making raw material slag filtered out can as the feed of livestock, and nutritive substance is easy to absorb, and has saved the use to corn and wheat, reduces the cost of peasant household; Using non-woven fabrics as microbial film, cheap, the life-span is grown, greatly reduce cost; Whole sewage treatment process all runs through the idea of energy-saving and environmental protection, achieves sustainable development and sees.
