生物滞留池处理化粪池出水的试验研究

指出了化粪池是农村生活污水收集和处理的主要方式,但作用有限,直排仍会造成水体污染。化粪池出水经进一步处理后排入附近沟塘或就地农用是可行途径之一。为此,进行了不同水力负荷运行条件下的试验结果表明:生物滞留池对处理化粪池出水中的LAS、COD cr、NH⁺₄-N的效果显著,平均去除率分别为94.6%、97%和88%,出水水质均达到了《城镇污水处理厂污染物排放标准》(GB18918-2002)一级A标准;对化粪池出水中TN和TP的处理效果不佳,出水水质未能达到排放标准。总体出水水质符合《农田灌溉水质标准》(GB5084—2005)中灌溉蔬菜的标准,因此可以考虑将其作为农村灌溉用水。试验研究结果表明生物滞留池可作为化粪池出水的简便处理单元。     

纸浆碱处理段废水的电化学降解研究

用硅碳椿作为阳极，不犭钢网为阴极对纸浆氯漂碱处理段废水进行电氧化反应。结果表明；电解过程中pH值先升高后降低，电导率先降低后升高，废水色度和COD值在开始处理阶段会下降很大，pH值对色度降低的影响不大，同时通过紫外光谱图也表明硅碳棒降解废水是有一定的效果。

HPLC evaluation of resin acid degradation with ozone treatment of pulp mill effluent

Summary Pulp mill effluent in the pH range of 7 to 8.5 was found most suitable for ozone treatment. Both resin acids and phenolic compounds were degraded in similar efficiency. Among the various resin acids, dehydroabietic acid (DHA) was found to be the most resistant to ozone degradation. The determination of DHA in the treated effluent can therefore reflect the degree of completeness of the effluent treatment. A simple and fast HPLC method reported previously for the determination of DHA was found to serve well for this purpose. Results are demonstrated by treatments of various pulp mill effluents.

Improvement of dispersing property of sodium sulfite-formal-dehydeanthraquinone pulping effluent by treatment withCoriolus versicolor

A strain of the fungusCoriolus versicolor was inoculated periodically into potato dextrose agar (PDA) slants containing the effluent to enhance the natural ability to grow in the effluent. The acclimated strain grown in the 50% effluent-containing PDA slant and the original strain were employed to treat the effluent. The acclimated strain could grow in a higher concentration of the effluent than the original unacclimated one. Both the original and acclimated strains improved the dispersing ability of the effluent, especially the acclimated strain because of its higher laccase secretion. The dispersing ability of the SFP effluent was improved to a level comparable to a commercial lignosulfonate product because it was strongly polymerized by the fungus. During the fungal treatment, more than 50% of the sugars were removed from the effluent, thereby increasing the purity of the SFP lignin product.This work was presented at the 48th annual meeting of the Japan Wood Research Society, April 3–5, 1998, Shizuoka, Japa     

饲料植物处理猪场厌氧废液的pH值变化规律

研究了基于3种饲料植物空心菜、水稻和水葫芦处理体系中猪场厌氧废液的pH值变化规律以及其与其它水质指标之间的关系.结果表明:随着植物生长,各处理体系中废水pH值总体呈下降趋势,在处理第15天时,空心菜和水稻处理体系中废水pH值从起初8.22降至约为7,水葫芦处理体系中pH值则降为5;随着处理时间增加,pH值变化量增大,COD、NH4 -N、TN、TP去除率也在提高.
