Gallery Sauce Wastewater-treatment Facilities Experimental Study

With the rapid development of condiments, organic content,Wastewater color heavy sauce to the increasingly serious environmental pollution caused by water.Process the sauce at home and abroad to study less, but also fails to address the water quality characteristics identify appropriate treatment.Experimental study on the main street through this type of sewage treatment facilities sauce wastewater treatment.Test using artificial water distribution.After more than a year of operation found that CODcr concentration 3000mg/L,Volumetric loading of 0.5kgCOD/m3 ? d,1kgCOD/m3 ? d,2kgCOD/m3 ? d,3kgCOD/m3 ? d,Anaerobic part ABR (Anaerobic baffled reactor) baffle anaerobic reactor at CODcr removal rate of 70%.the results were very good.ABR anaerobic reactor in organic nitrogen occurred amination reaction, the higher value of the effluent ammonia.Experiments were found, Aerobic and anaerobic biomass contact oxidation pond effluent water ABR part of the difference is small compared to the CODcr value. Ammonia is a significant drop in value and there is a certain degree of bio-contact oxidation pond effluent produced nitrite. These results show that aerobic CODcr not part of the removal, So instead of falling through the static analysis of the reasons for CODcr. Found the soy complex wastewater, which contains large amounts of refractory material and color. These color material CODcr is the result of the continued decline reasons.CODcr concentration regard to 1500 mg/L, static small pilot plant test.After two months of operation, the anaerobic CODcr around 500 mg/L,Aerobic CODcr 350mg/L around the aerobic part of the CODcr removal efficiency significantly.According to the results of the static tests, the dynamic test influent concentration to 2000mg/L, some time after the operation.Some sewage treatment facilities in the corridor ABR anaerobic treatment is still relatively good, CODcr removal rate between 60%-70%.Meanwhile, with better aerobic parts of the removal of CODcr, aerobic CODcr 350mg/L,the removal of between 30-40%.Tested : excessive concentration sauce wastewater, sewage treatment facilities will be affected corridor effect;Gallery sewage treatment facilities on the CODcr in 2000 mg/L about certain sauce wastewater treatment.
