空压机噪声的治理方案和效果

不同的噪声源有不同的治理方法,同一类噪声源,由于所处的地域不同、场所的不同以及标准要求不同,治理方案往往也不同.一项噪声治理工程,既可以是声源控制、消声、吸气、隔声和减振各项措施的综合运用,也可以单独采用某项措施去达标,其差异之一就体现在工程的经济性.宁波市海曙噪声防治研究所在治理一例空压机噪声时,则很恰当地把握了治理工程的经济性原则.充分考虑治理的经济条件,使企业少花钱,又能达到预其的效果.治理后,真正

Treatment of refectory oily wastewater by electro-coagulation process

Electro-coagulation was used to treat refectory wastewater with high oil and grease contents. Different operational conditions were examined, including pH, current density, reaction time, conductivity, electrode distance and inlet concentration. The optimum current density was 10-14 A m(-2) within 30 min depending on the wastewater properties tested. Conductivity had little effect on the treatment efficiency. Although the addition of extra salts (e.g., sodium chloride) to the wastewater did not help increase the pollutant removal efficiency, it could save the power consumption significantly. The COD(Cr) and oil removal efficiency descended with increasing electrode distance. The optimal electrode distance was determined to be 10 mm for this equipment in consideration of the treatment cost and efficiency together. The pH effect on the performance of the electro-coagulation process was not very significant in the range of 3-10. The removal efficiency of oil and COD(Cr) under normal condition exceeded 95% and 75%, respectively.

水力停留时间对曝气生物滤池处理效能及运行特性的影响

通过实验室模型试验研究了曝气生物滤池处理模拟生活污水的效能，分析了水力停留时间(HRT)变化对曝气生物滤池处理效果及运行特性的影响规律。研究发现，当HRT大于0.6h时，曝气生物滤池具有良好的有机物和浊度的去除效果，而当HRT为0．4h时，处理效果则显著下降；反应器的硝化反硝化脱氮能力受HRT的影响比较明显，缩短HRT将使氨氮和总氮去除率迅速下降，当HRT为1.25h时，氨氮和总氮去除率分别达到70%和40％以上；缩短HRT会在一定程度上促进亚硝酸盐积累现象的发生。而反应器的过滤周期则与HRT呈明显的线性关系。     

Biotreatment of H2S- and NH3-containing waste gases by co-immobilized cells biofilter

Gas mixture of H2S and NH3 in this study has been the focus in the research area concerning gases generated from the animal husbandry and the anaerobic wastewater lagoons used for their treatment. A specific microflora (mixture of Thiobacillus thioparus CH11 for H2S and Nitrosomonas europaea for NH3) was immobilized with Ca-alginate and packed inside a glass column to decompose H2S and NH3. The biofilter packed with co-immobilized cells was continuously supplied with H2S and NH3 gas mixtures of various ratios, and the removal efficiency, removal kinetics, and pressure drop in the biofilter was monitored. The results showed that the efficiency remained above 95% regardless of the ratios of H2S and NH3 used. The NH3 concentration has little effect on H2S removal efficiency, however, both high NH3 and H2S concentrations significantly suppress the NH3 removal. Through product analysis, we found that controlling the inlet ratio of the H2S/NH3 could prevent the biofilter from acidification, and, therefore, enhance the operational stability. Conclusions from bioaerosol analysis and pressure drop in the biofilter suggest that the immobilized cell technique creates less environmental impact and improves pure culture operational stability. The criteria for the biofilter operation to meet the current H2S and NH3 emission standards were also established. To reach Taiwan's current ambient air standards of H2S and NH3 (0.1 and 1 ppm, respectively), the maximum inlet concentrations should not exceed 58 ppm for H2S and 164 ppm for NH3, and the residence time be kept at 72 s.

On-site biological remediation of contaminated groundwater: a review

On-site biological treatment has been used for groundwater cleanup from industrial and agricultural chemicals. The pump-and-treat efficiency is controlled by retardation of contaminants by sorption onto the saturated subsurface solids and by the presence of non-aqueous-phase liquids in the aquifer. On-site bioreactors have been widely used for treatment of contaminants such as petroleum hydrocarbons, monoaromatic hydrocarbons, chlorinated aliphatics and aromatics. The most commonly used reactor types for groundwater include the following: trickling filter, upflow fixed-film reactor and fluidized bed reactor. Bioreactor processes have limitations mainly because of their design to operate at elevated temperatures and thereby by high operational costs.     

O3、H2O2／O3及UV／O3在焦化废水深度处理中的应用

采用O3、H2O2／O3及UV／O3等高级氧化技术（AOPs）对某焦化公司的生化出水进行深度处理，考察了O3与废水的接触时间、溶液pH、反应温度等因素对废水COD去除率的影响，确定出O3氧化反应的最佳工艺参数为：接触时间40min，溶液pH8．5，反应温度25℃，此条件下废水COD及UV254的去除率最高可达47．14％和73．47％；H2O2／O3及UV／O3两种组合工艺对焦化废水COD及UV254的去除率均有一定程度的提高，但H2O2／O3系统的运行效果取决于H2O2的投加量。研究结论表明，单纯采用COD作为评价指标，并不能准确反映出O3系列AOPs对焦化废水中有机污染物的降解作用。
