抚顺市区地下水水质污染现状评价

结合1991和2004两年丰水期34个监测点（监测井位）的监测资料，从地下水化学类型的变化角度阐述抚顺市地下水主要含量成分的改变，认为抚顺市区地下水质是受到了不同程度的污染，随着环境保护工作的深入、地面污染源的治理，地下水质有一定程度的改善，但却是非常缓慢的。     

Membrane fouling control by ultrasound in an anaerobic membrane bioreactor

In this study, ultrasound was used to control the membrane fouling online in an anaerobic membrane bioreactor (AMBR). Short-term running experiments were carried out under different operating conditions to explore feasible ultrasonic parameters. The experimental results indicated that when the crossflow velocity was more than 1.0 m/s, membrane fouling could be controlled effectively only by hydrodynamic methods without ultrasound. When ultrasound was applied, an ultrasonic power range of 60–150 W was suitable for the membrane fouling control in the experimental system. The experimental results showed that the membrane fouling was controlled so well that membrane filtration resistance (ΣR) could stay at 5 × 10¹¹ m⁻¹ for more than a week with the crossflow velocity of 0.75 m/s, which equaled the effect of crossflow velocity of more than 1.0 m/s without ultrasound.

Toxic effects of wastewater from various phases of monosodium glutamate production on seed germination and root elongation of crops

To make a comprehensive assessment on monosodium glutamate (MSG) wastewater pollution, a pollution exposure experiment was carried out on the seed germination and root elongation of wheat, Chinese cabbage and tomato by using the wastewater discharged from different processing phases of MSG production. The results showed that there were significantly positive linear relationships between the inhibitory rates of wheat seed germination and root elongation and the COD_cr of the mother liquor scraps. The toxicity of MSG wastewater to the test crops was in the order of tomato > Chinese cabbage > wheat, indicating that tomato was the most sensitive to the wastewater, and could be considered as an ideal toxic bioindicator. The half-effect concentrations (IC₅₀) based on the seed germination and root elongation of the test crops exposed to the wastewater discharged from various processing phases of MSG production was 22.0–32 432 and 17.3–3320 mg/L, respectively.

船上生活饮用水中亚硝酸盐污染及其治理

经测定，某航次船上饮用开水中亚硝酸盐的浓度为0.180mg/dm^3，超过GB8537-87标准35倍；冷自来水中为1.76mg/dm^3，超标350倍。航次结束后，从码头自来水管取的四份水样中亚硝酸氮则全部未检出。本文报道了船上饮用水与生活用水受到具有致癌性的亚硝酸盐污梁，并为消除亚硝酸盐污染提出了对策。
