The Treatment Of Wine Distillery Wastewater By The Sorbent Adsorption With Microwave Catalytic Oxidation

At home and abroad more wine distillery wastewater by biological wastewater treatment, but in the long, cold winter in Xinjiang, biological reactor not operation correctly. Adsorption-Microwave Catalytic Oxidation process for treatment of high efficiency, under the influence of the microwave can greatly shorten the reaction time, but also can improve the oxidation efficiency of Fenton reagent, while the microwave radiation absorbent material can produce very high local temperature "hot spots" directly to the decomposition of organic matter, improve the treatment efficiency. High temperature reaction in the cold winter can be normal operation.In this study, the organic modified bentonite process was optimized. Microwave catalytic oxidation combined with absorption was studied for treating static and flowing wastewater wine distillery wastewater. Treatment wastewater wine tail water with SBR reactor start-up and reaction kinetics was studied. The main conclusions are as follows:1. The effects of microwave power, irradiation time, solid-liquid ratios and remodel dosage on the degradation were examined, respective. The best treatment conditions were remodel dosage 120 mmol/100g, solid-liquid ratios 1:10, irradiation time 2 min, microwave power 540 W, respective. Under these conditions, the degradation rates of COD overstep 40.2 %. Compare technics conditions of microwave and conventional heating. Under microwave heating conditions, decrease remodel dosage, water dosage and irradiation time.2. Microwave catalytic oxidation combined with absorption was studied for treating wine distillery wastewater. Activated carbon as sorbent of the entire reaction system, under these conditions, decrease sorbent dosage, rradiation time, and the activated carbon can be reused, in response to greatly decrease the cost of activated carbon sorbent as the reaction system has certain advantages. Na-bentonite as an adsorbent, the entire reaction system a high COD removal rate, Na-bentonite market, low prices, is a more suitable adsorbent used for the reaction system; Organic bentonite Compared with sodium bentonite, as the adsorbent of the system, COD removal rate is not greatly improved, the market price of more expensive, but also bring new contaminants, not suitable for the adsorption of microwave reaction system agent.3. Microwave catalytic oxidation combined with absorption was studied for treating wine distillery wastewater. The factors of wastewater flux, microwave power, pH, dose of H2O2, and their effects on wastewater COD remove rate were studied. Based on the results of single factor test, the remove rate was analyzed using method of response surface analysis and orthogonal experiments. The optimal conditions were confirmed, respective.4. By detecting targets of SBR reactor, the results showed that it had a short startup time and a strong capability to resist shock of high concentration load. By researching reaction kinetics of SBR reactor, the value of temperature coefficient 0 was 0.9577, at the same time, the relation between reaction rate coefficient (k) and the temperature (K) was ensured.Process conditions are optimized dynamic and COD degradation kinetics of SBR reaction system for theoretical basis for practical application. Under the current dynamic sodium bentonite as adsorbent treatment process did not show its advantages, improve the experiment device of flowing wastewater to achieve better treatment effect.
