煤炭行业的"三废"及其治理

预计煤炭在中国一次能源消费中的比重到2050年仍占50％，仍将是中国重要的能源资源，在煤炭开发、运输，使用过程中会产生严重的环境污染问题，废渣、废气、废水的数量巨大，治理难度大，耗资高，对环境和人类生存造成巨大的威胁，因而既要开采煤炭，又要重视治理污染。     

EM菌强化SBR处理生活污水的试验研究

研究了EM-SBR处理生活污水的工艺特征和EM菌的最佳投加周期.结果表明:EM-SBR反应器在非限制性曝气方式下处理低浓度生活污水,有机负荷宜控制在0.22～0.40kgCODCr/kgMLSS·d,氨氮负荷宜控制在0.030kgNH3-N/kgMLSS·d以下,泥龄可控制在5～28d之间.EM菌的最佳投加周期为15个周期.     

喷雾干燥法烟气脱硫过程的模拟试验研究

本文模拟试验研究了喷雾干燥法烟气脱硫中脱硫渣再循环利用、气体参数（ＳＯ２浓度、气速、气温）及浆液参数等对脱硫过程的影响，并分析了喷雾干燥塔内传热传质过程。本文结果将有助于改进喷雾脱硫塔的设计和操作。     

三种固体废弃物综合利用的初步研究

从环境建设的可持续发展出发 ,结合天津开发区在基础设施及园林绿化建设中面临土源紧缺以及周边地区存在大量的海湾泥、粉煤灰、碱渣土等固体废弃物的现实 ,在详细研究了3种废物的物理、化学性质的基础上探讨了用这些废物代替农田客土的可行性。实验及推广应用结果表明 ,这些废物按适当比例混合后能够形成一种可替代种植客土的新型土壤 ,这种新型土壤的最佳配比(即海湾泥与粉煤灰或碱渣土 )比例为3:1 ,同时该配比基质对植物生长的适宜性优于滨海盐土。

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.     

Effect of leachate recycling and inoculation on the biochemical characteristics of municipal refuse in landfill bioreactors

Activity development of key groups of enzymes involved in municipal refuse decomposition was measured in laboratory landfill bioreactors with and without leachate recycling and inoculation for about 210 days.The results showed that the enzymes(amylase,protease,cellulase,lipase and pectinase)were present in fresh refuse but at low values and positively affected by leachate recycling and refuse inoculation.The total average of cellulase activity in digesters D3 operated with leachate recycling but no inoculation,D4 and D5 operated with leachate recyling and inoculation was much higher than that in digesters D1 and D2 without leachate recycling and inoculation by 88%-127%,117%-162%and 64%-98%.The total average of protease activity was higher in digester D4 than that in digesters D1,D2,D3and D5 by 63%,39%,24%and 24%,respectively,and the positive effect of leachate recycling and inoculation on protease activity of landfilled refuse mainly was at the first two months.The total average of amylase activity was higher in digesters D3,D4 and D5 than that in digesters D1 and D2 by 83%-132%,96%-148%and 81%-129%.During the early phase of incubation,the stimulatory effect of inoculation on lipase activity was measured,but refuse moisture was the main factor affecting lipase activity of landfilled refuse.The inoculation,initial and continuous inoculation of microorganisms existing in leachate,was the mainly stimulatory factor affecting pectinase activity of landfilled refuse.
