High-strength Syrup Wastewater Processing Technological Research

The syrup is the agricultural product preliminary working product, is same with other agricultural product processing industries, its processing production but has the raw material supply influence the seasonal production the characteristic. Therefore, the high-strength syrup wastewater production produces the organic waste water has the high potency, the wastewater water volume and the water quality changes major and the seasonal characteristic.This experiment for the actual project utilization project, experiments in refers to each highly concentrated organic waste water processing method in the foundation, the union project actual movement reality, discovers suits the local reality, the economy and the effective waste water processing craft. The key solution syrup waste water processing difficulty is big, the cost high difficult problem.The experimental attempt after pollutes shoulders heavily ultra filters the tail fluid to carry on alone processes enters the processing system again, after thus reduces the waste water the pollution load, achieved reduced the following processing unit the design handling ability goal, the success has solved the enterprise most sensitive cost problem, had the high promoted significance to similar fruit juice waste water processing.In the craft choice, refers to the domestic and foreign related projects experience and the project parameter, proposed suits the local actual craft route initially, the union small scale pectin separation simulation test, obtains the preliminary suitable concentration syrup production waste water processing craft, again passes through the actual project movement effect analysis, obtains the best waste water processing craft.This project finally processing craft is: After ultra filters the waste water, the high alkali waste water enters the neutralization tank to have and the response, the flocculent precipitate separation enters the settling basin, the separating tank together after the general density clean waste water, after the hydrolisis acidification, the gas floats, the CASS pond, the artificial wetland in turn and the filter tank. The system moves for 4 months, the water leakage CODcr density stabilizes in 60 ~ 90mg/ L, BOD stabilizes in 10 ~ 20mg/ L; SS stabilizes in 20 ~ 60mg/ L; The water leakage achieved the national sewage discharges...
