The design parameters and the operational aspects of mine water disposal project in Fengxi Xinyu coal mine were introduced. The primary disposal process included neutralization, coagulation settling and mechanical filtration process, and reverse osmosis (RO) process for desalination were used to treat mine water with high-turbidity, high-hardness and high-salinity. The results showed that the pretreated mine water could be used for washing coal, and the quality of permeate liquid of RO for water with milk excelled the national standards for drinking water. New water source was supplied to the coal mine, the recycle of mine water was resource engineering practice.

A series of experiments were performed to remove toluene from a gaseous influent at normal temperature and atmospheric pressure by non-thermal plasma generated dielectric barrier discharge coupled with nano-Ba0.8Sr0.2Zr0.1Ti0.9 O-3 catalyst. We were innovative to prepare nano-Ba0.8Sr0.2Zr0.1 Ti0.9O3 catalyst by ourselves and use it in the plasma reactor. The best removal efficiency of toluene arrives at 95% in condition of toluene concentration of 600 mg/m(3), flow rate of 1 mL/min and electric field strength of 14 kV/cm. Nano-Ba0.8Sr0.2Zr0.1Ti0.9O3 not only resulted in greater enhancement of toluene removal efficiency and reducing energy efficacy on treating with the same quantity of toluene, but also controlled byproducts effectively in plasma process.

The water quality of lignite-derived water produced from Hot Press Upgrading (HPU) is in breach of the reuse standard for power plant's circulating cooling water. This study assesses the water characteristics of lignite-derived water as follows: The BOD5/COD ratio is 0.85. The pH value of lignite-derived water samples is from 6.65 to 6.85. The lignite-derived water's properties parameters such as turbidity, BOD5, CODCr, Mn and NH3-N are higher than the reuse standard for power plant's circulating cooling water. A combined treatment process, A(2)/O-UBAF, was developed for remediation of the lignite-derived water in this paper. After the treatment, the lignite-derived water's quality can meet the reuse standard for power plant's circulating cooling water in China.

An acetic acid microbial biosensor was developed for environmental monitoring. The microbial biosensor consisted of an immobilized cell membrane and an oxygen electrode. The results showed that the optimum pH of buffer solution was 6.48, the optimum temperature of buffer solution was 33°C and the optimum concentration of buffer solution was 0.01mol/L for acetic acid's determining. The linear range was found to be from 5.0 to 30 mg/L of acetic acid and the regression equation was y=0.51x+1.66 (correlation coefficient 0.9998). 23 kind of interferential substances, which have the similar chemical characters and molecular weights as acetic acid, were determined in the experiment. The biosensor was found to have an extend activity of 90 days with more than 600 determinations.
