With demand increasing year by year ice cream, ice cream factory wastewater rapidly. Currently, the main use of industrial waste water ice flotation - Biological Treatment Act, which effluent quality can meet the national emission standards, but only for the above process of decomposition of organic matter in waste water consumptive, no sugars and other organic matter use, combined with sustainable development policy paper discusses the use of ice water resource technology research. In this study, survey research status and the Task Force on the basis of preliminary findings to the city sewage treatment plant sludge microbial sources for the production of hydrogen, hydrogen production by water ice matrix to study ice water resource use processes. Test focuses on ice cream wastewater pretreatment, ecological factors, and hydrogen production reactor process conditions. Ice cream wastewater pretreatment show that: ice cream after pretreatment of wastewater flotation cumulative hydrogen production 70.97 mL, hydrogen production without pretreatment is 4.65 times. Control of wastewater pH of 6.2 ice cream and a temperature of 36 ± 1 ℃, sludge and waste water volume ratio of 0.08, iron dosage of 5mg / L, the cumulative hydrogen production could reach 98.98mL, total sugar utilization was 96.76 %, COD removal rate was 49.4%. CSTR reactor fed at intervals of 6h, stirring speed of 1 OOr / min, alkalinity is 600mg / L, the maximum cumulative hydrogen production 7970mL. On this basis, the use of response surface methodology to obtain a semi-continuous operating conditions than the hydrogen production rate and COD removal for feeding interval (A), stirring speed (B), alkalinity (C) of the quadratic regression Equation (1) and Equation (2), the models 1 and 2. The variance test, two regression models were highly significant (P lt; 0.0001), lack of fit test is not significant, that these two models suitable effective, actually has some significance. Hydrogen production rate compared to the best response value, the optimal feeding intervals 5.73h, stirring speed 105r/min, alkalinity value 672.09mg / L; worth as a response to the COD removal rate to the optimal Operating conditions feeding intervals 7.85h, stirring speed 105r/min, alkalinity value 759.28mg / L to municipal sewage treatment plant sludge microbial sources for the production of hydrogen, hydrogen production by water ice matrix, for ice cream, water resource is feasible. The process of urban sewage treatment plant wastewater sludge and ice cream after simple treatment, not only can produce hydrogen gas, renewable resources, but also turning waste into treasure.
