Through the investigation of pollution sources and pollution conditions, we believe that pollution pollution should be lightly polluted and severely polluted based on the principles of re-treatment and light-discharge. In the treatment process, different plans should be adopted to achieve Less investment and quick results. According to our investigation and analysis of pollutants, we have taken the following measures. In order to reduce the amount of treatment, the method of clearing and diverting the sewage was adopted, that is, the cooling water and the brush bottle bottled water were directly discharged separately. The water ring type vacuum pump for the wine-filling machine uses the circulating water tank alone. In order to ensure the cooling temperature, a cooling device may be added in summer so as to recover the brush tank water of the wine store after reaching a certain alcohol concentration, and the water concentration of the water in the filter cloth is higher, and the concentration is higher. Distillation or evaporation is used to remove alcohols, acids, aldehydes and esters. This method of investment is less effective. We have conducted distillation experiments on water samples that have caused excessive levels in the winery. The concentration of CODcr before distillation was 3286.8 mg/L, and it was only 65.62 mg/L after distillation. The desired result was achieved.
Prevent or reduce the amount of wine mash and dregs falling in and shorten the residence time of moromi and material at the bottom of the pot. The past daily cleaning and weekly cleaning are completely changed to be thoroughly cleaned by each pot, which can effectively control the amount of CODcr produced in pot bottom water. Reducing the position of the water vapor ring at the bottom of the pot promotes full vaporization of the tail wine to reduce the increase in CODcr caused by alcohol residues. Without affecting the liquor yield and quality, minimizing the water content of the fermented grains to reduce the reflux flow during the distillation process is also an effective measure to control the increase of the CODcr value caused by the distillation process. We took the above-mentioned measures after a week of experimentation, and the total amount of CODcr produced per plutonium dropped from 5.75 Kg before survey to less than 3 Kg, which is an effective method to control the generation of CODcr in pot bottom water.
