Effect of domestic sewage on growth of phytoplankton-mathematical model

A mathematical model relating to the change in phytoplankton biomass in the period of growth and nutrient concentration in the media was proposed on the basis of the Monod equation and was testified by simulation experiments. Analysis of the experiment data showed that: the half-saturation constants for growth Kp (μmol/L) for Skeletonema, Chaetoceros and Prorocentrum were 5.52, 1.90 and 0.46, respectively; the balance between stimulation of nutrients and the inhibition of some other materials was found in the effect of domestic sewage on algal growth and the stimulation played a leading role; domestic sewage was more stimulative on dinoflag-ellate than on diatom and chlorophyte when the assemblage of the algae was cultured. The experiment suggested that mathematical model reasonably explained the characteristics of phytoplankton growth in different nutrient conditions and was worthy to be further improved for eutrophication prediction in off-shore water.

生活污水对蝌蚪红细胞微核及核异常的诱导

利用青蛙蝌蚪红细胞微核试验,检测了城市生活污水处理厂各级处理工艺出水的诱变活性。在l6d生话污水处理的实验中,青蛙蝌蚪红细胞微核细胞率及核异常率2d后就呈现统计上的显著增加,并随暴露时间的延长而增高,第8天达到最大值。在不同浓度混合污水暴露实验中,蝌蚪红细胞微核细胞率和核异常率呈现明显的剂量依赖性增加。实验结果表明:城镇生活污水具有较强的诱变活性,一级和二级处理工艺出水也具有一定的诱变活性。现有污水处理工艺有待于进一步改进。     

工业蒸汽锅炉高效燃烧支持系统综合应用研究分析

呼和浩特市为防治城市空气污染，近年来拆除了大量的分散小锅炉，实行集中供热。但必须保留下来的中型锅炉仍以煤炭为燃料，燃煤排污依然是城市环境的主要污染源。本文针对这一问题，立项研究，分析指出通过锅炉高效燃烧支持系统的综合应用，达到提高锅炉燃烧效率，节能降耗、减少排污的目的。

Toluene removal characteristics by a superimposed wire-plate dielectric barrier discharge plasma reactor

A superimposed wire-plate dielectric barrier discharge reactor was used to remove toluene in this study. The effects of oxygen content, gas flow rate, gas initial concentration and with/without catalyst on toluene decomposition were investigated. It was found that an optimal toluene removal was achieved when the oxygen content was about 5%. Under this condition, the highest toluene removal efficiency of 80.8% was achieved when the gas concentration was 80 mg/m^3. The toluene removal efficiency decreased with the increase of the gas flow rate and the initial concentration of toluene. In addition, the ozone concentration decreased with the increase of the initial concentration of toluene. It suggested that combining DBD （dielectric barrier discharge） with Co3O4/Al2O3/foam nickel catalyst in-situ could improve the toluene removal efficiency and suppress ozone formation. Products analysis showed that the main products were CO and CO2 when oxygen was more than 5%.
