	Abstract:The sulfite/UV process is an promising alternative to remediation of a wide variety of recalcitrant contaminants such as halogenated organic compounds by producing powerfully reducing species, hydrated electron (eaqˉ). This study was intended to assess the efficiency of the process and to optimize the system. Selecting monochloroacetic acid (MCAA) as the simple model compound, energy efficiency of the reductive dehalogenation by the process was assessed based on the degradation kinetics of MCAA. The energy efficiency was analyzed by taking into account both of the electric energy input and chemicals consumption. The energy efficiency generally increased with increasing UV dose while showing a parabolic profile with respect to S(IV) dosage. Thus, the process could be optimized by controlling UV dose and S(IV) dosage in tandem, and several optimization approaches were also proposed and discussed. The process still shows effects in reducing MCAA in the realistic surface water, and the efficiency EE/O for reductive dehalogenation was estimated to be about18.6 kWh m-3 order-1 by the sulfite/UV process, suggesting that the process was efficient and promising in destroying many recalcitrant contaminants.

	Abstract:Biofilm biodegradation was coupled with UV photolysis using the internal loop photobiodegradation reactor (ILPBR) for degradation of quinoline. Three protocols -- photolysis alone (P), biodegradation alone (B), and intimately coupled photolysis and biodegradation (P&B) - were used for degradation of quinoline in batch and continuous flow experiments. For a 1000 mg/L initial quinoline concentration, the volumetric removal rate for quinoline was 38% higher with P&B than with B in batch experiments, and the P&B kinetics were approximately the sum of kinetics from the P and B experiments. Continuous-flow experiments with an influent quinoline concentration of 1000 mg/L also gave significantly greater quinoline removal in P&B, and the quinoline-removal kinetics for P&B were equal to the sum of the removal kinetics for P and B. P&B similarly increased the rate and extent of quinoline mineraliation. The COD-removal kinetics for P&B were equal to the sum of kinetics for P and B, and the rate-limiting step for mineralization was transformation of quinoline.

	Abstract:IFluorescence quenching method was employed to determine the binding constant (Koc) of Humic acid (HA) - Pyrene (Py). The effects of pH value, ionic strength and heavy metal (HM) ions on the Koc were investigated and used to discuss the interaction mechanism between HA and Py. A fluorescent probe method was established and firstly applied to study the interaction between HA and Py by investigating the variation of I1/I3 with the chemical conditions of HA solution. Experimental results indicated that I1/I3 values showed an opposite trend compared to that of Koc, but an identical explanation on the interaction between HA and Py was obtained. The effects of HM ions on the interaction between HA and Py were dependent on the binding sites of HA and HM ions which was located at the carboxyl and hydroxyl. 1H NMR was applied to search for the binding site between HA and Py which was located at aliphatic chain of the HA.n this paper.

	Abstract:In recent years, the rapid growth of the economy increasing demand for energy, promote the increase of coal extraction. In the process,the waste of resources and environment pollution becomes more and more serious. This paper is based on the successful cleaner production audits of No.11 Coal Mine of Pingdingshan Coal Industry Group. Comprehensive analyzed the clean production process and key steps of practice, and economic, environmental and social benefits. the existing problems are discussed and analyzed, and puts forward the countermeasures and Suggestions. This cleaner production audits were produced 29 feasible schemes, including 21 low cost schemes, and 8 high cost schemes. after schemes implementation ,the main pollutant, COD reduce 50t/a, SO2 reduce 39.1t/a, mine water recycling improve 23.3% , Sewage reuse after realizing part. Tons of coal consumption reducing 2600kwh/million t. Through the cleaner production audits for the enterprise to realize the sustainable development, to lay the good foundation stralegy of purpose, and for other coal enterprises to develop cleaner production audits has certain theoretical guidance and practical application value

	5. The exchange of acetaldehyde between the atmosphere and plants and its forming mechanism

	Environmental Science and Techology 30 June 2008
	Show/Hide Abstract \| Cite this paper︱Full-text: PDF (0 B)

	Abstract:The exchange of acetaldehyde between atmosphere and plant leaves includes three processes: 1) acetaldehyde is emitted from plant leaves; 2) acetaldehyde in the atmosphere deposits to the leaf-surface; and 3) acetaldehyde is absorbed and metabolized by plants. The physiological and environmental factors which controlling these processes were reviewed. Acetaldehyde emission from plants in some unfavorable environment functions as external signal for within-plant communication, serving also a systemic response to local damage. The mechanism of acetaldehyde production was also discussed. With the capability of absorbing acetaldehyde, plants can be used to detoxify the air. Phytoremediation will be one of the most promising approaches for cleaning up the air organic pollutants. While, plants are also important pools of acetaldehyde production, especially under environmental stresses such as flooding and anaerobic condition.

	Abstract:This study was conducted to reduce ammonia nitrogen (NH3-N) in wastewater effluents by constructed wetland systems under four different influent ammonia nitrogen concentrations. To study the efficiency of ammonia nitrogen (NH3-N) removal through lab scale experiments in Vertical Integrated Constructed Wetland (VICW) systems. Constructed wetland, being simple in construction and maintenance and operation, is a biological system, which applies the interaction between media, plants, wastewater and microorganisms during the degradation of pollutants found in the wastewater. Laboratory scale experimental set-up tank was located at in Hydrology laboratory of Hohai University, Nanjing, China with dimensions of 1.0 m in length, 0.5 m in width and 0.8 m in depth. The media used were sand and rocks. The sand of down-flow tank is 0.7m and the other up-flow is 0.6m. The cattail plants (Typha angustifolia.) were chosen for all reactors of the constructed wetland system. The wastewater from the tank is using pumps to maintain a fixed flow rate at HRT of 1 day, 2 days, 3 days, 4 days and 5 days. The hydraulic retention time (HRT) was about 3 days for the best constructed wetland systems. Influent and effluent were analyzed for NH3-N, COD, TP and TN once every three days. The influent ammonia nitrogen (NH3-N) concentrations for four different concentrations of ammonia nitrogen (NH3-N) experimental runs were ~1.5, 13, 26 and 35 mg/l. Performance of Vertical Integrated Constructed Wetland (VICW) systems were evaluated and compared for different ammonia nitrogen (NH3-N) concentrations in the synthetic wastewater used for this study.
