Description
Technical Field
The utility model belongs to the technical field of the water treatment, especially, relate to a sauce fragrant wine effluent disposal system.
Background
The waste water from brewing Maotai-flavor liquor belongs to high-concentration organic waste water, the COD concentration is as high as 10000mg/L, and if the waste water is discharged beyond the standard, the waste water can cause serious influence on the surrounding environment, so that the waste water treatment for producing Maotai-flavor liquor can reach the standard and is of great significance.
In the production process of the Maotai-flavor liquor, sewage mainly comprises flushing water, pit bottom water, pot bottom water, cooling water and the like, and the wastewater contains high-concentration organic pollutants, raw material residues, vinasse and other fiber substances. The production of Maotai-flavor liquor takes sorghum as a raw material, wheat is used for making high-temperature distiller's yeast, the whole production cycle of each year goes through ten stages of sand discharging, sand inserting, liquor production for seven times, vinasse loss and the like, each stage lasts for 35-40 days, sewage is continuously discharged in the period, and the concentration of pollutants is continuously increased along with the progress of the stages until the vinasse loss period reaches a peak value. According to related research, the peak value of the concentration of pollutants in yellow water discharged during the production period of the sauce-flavor wine vinasse can reach more than 3 times (COD can reach 350000mg/L) at ordinary times, so that a system designed according to the concentration of waste water discharged at ordinary times is inevitably difficult to adapt to the vinasse-losing period, and almost always overproof phenomenon occurs. The problem becomes an important reason that the wastewater treatment in the sauce fragrant wine industry is difficult to reach the standard stably.
At present, the prior art for treating the wastewater of the sauce-flavor wine does not collect the high-concentration yellow water in the production period independently, and directly mixes the yellow water into other production wastewater to enter a treatment system. Because the yield of the high-concentration yellow water is unknown and the mixing amount of the yellow water cannot be controlled, the water quantity regulating effect of the regulating tank adopted by the prior art is far greater than the water quality regulating effect. Therefore, the problem of excessive effluent caused by sudden increase of the concentration of pollutants in the spent grain production period cannot be solved by adopting the regulating tank in the existing design.
In addition, the ozone oxidation process commonly adopted in the prior deep treatment of the brewing wastewater has the problems of unstable reaction, high safety risk, high cost and the like, and a more stable, safe, economic and efficient advanced treatment method is still required.
In conclusion, how to solve the problem that the yielding water is difficult to reach the standard stably and the problem of advanced treatment process optimization caused by the multiplication mutation of the water quality brought by high-concentration yellow water in the production period of the sauce-flavor wine become important points to be solved at present.
