垃圾焚烧烟气中氯化氢的干法去除研究

采用干态固定床实验装置系统，研究去除垃圾焚烧炉烟气中HCl气体的主要影响因素及其规律。结果表明：选择适当的摩尔比α和颗粒度较细小的吸收剂，吸收效率和吸收剂利用率会提高；温度对净化效率影响不大；HCl气体浓度（ρHCl）对吸收剂的吸收效率（ηHCl）显著影响，ρHCl升高，则ηHCl增大；含有少量杂质的工业碱性废渣的利用率要大于纯化学试剂吸收剂；HCl气体排放标准在75mg／m^3时，可采用干法去除垃圾焚烧炉烟气中的HCl气体。     

Study of control strategy and simulation in anoxic-oxic nitrogen removal process

The control strategy and simulation of external carbon addition were specially studied in an anoxic-oxic(A/O) process with low carbon: nitrogen(C/N) domestic wastewater. The control strategy aimed to adjust the flow rate of external carbon dosage to the anoxic zone, thus the concentration of nitrate plus nitrite(NOx^- -N) in the anoxic zone was kept closed to the set point. The relationship was studied between the NOx^- -N concentration in the anoxic zone(SNo) and the dosage of external carbon, and the results showed that the removal efficiency of the total nitrogen(TN) could not be largely improved by double dosage of carbon source when SNO reached about 2 mg/L. Through keeping SNO at the level of about 2 mg/L, the demand of effluent quality could be met and the carbon dosage could be optimized. Based on the Activated Sludge Model No. 1 (ASM No. 1), a simplified mathematical model of external carbon dosage was developed, Simulation results showed that PI controller and feed-forward PI controller both had good dynamic response and steady precision. And feed-forward PI controller had better control effects due to its consideration of influent disturbances.

Micro-electrolysis technology for industrial wastewater treatment

Experiments were conducted to study the role of micro-electrolysis in removing chromaticity and COD and improving the biodegradability of wastewater from pharmaceutical.dye-printing and papermaking plants.Results showed that the use of micro-electrolysis technology could remove more than 90% of chromaticity and more than 50% of COD and greatly improved the biodegradability of pharmaceutical wastewater.Lower initial pH could be advantageous to the removal of chromaticity. A retention time of 30 minutes was recommended for the process design of micro-electrolysis.For the use of micro-electrolysis in treatment of dye-printing wastewater,the removal rates of both chromaticity and COD were increased from neutral condition to acid condition for disperse blue wastewater;more than 90% of chromaticity and more than 50% of COD could be removed in neutral condition for vital red wastewater.
