查询词典 activated sludge

And this strain degraded H〓S without lag time. The heterotrophic bacteria's generation period was short and its growth was rapid. The result of experiment indicated when the strain Hm-6 was applying to the packed tower, the startup was more quickly and the control was more convenient than the autotrophic bacterium. Applying to deodorize the H〓S, the better removalability could be got. At the same time, comparing with the system used at home of which the biofilm directly formed with activated sludge, it runs in the neutral condition, has lower corrusivity to the equipment and was liable to handle. And this system didn't need the acclimation to become biofilm, so it can save a rather long acclimation time.

异养菌虽然不以硫化物作为能源物质，但其世代周期短、生长迅速，运行管理比自养菌更为方便，具有周期短，启动迅速等优点，接种了菌株Hm-6泥炭生物填料塔，对低浓度H〓S有较高的去除效果，且没有延迟期，与国内通常采用的直接以活性污泥挂膜的方式相比，应用该菌的脱臭系统在中性条件下运行，对设备的腐蚀性较低、运行过程较易控制，具有很好的应用前景。

Acclimate activated sludge with bleaching wastewater, isolate and depurate some single bacterium, select effective dominant bacteria with the removal of CODcr and organic chlorine as indicatrix and immobilize them to improve the removal of organic chlorine in bleaching wastewater.

用该废水驯化活性污泥，从中分离纯化出单一菌种，以CODcr和有机氯为指标，筛选出降解效果好的优势菌，并对其进行固定化，提高漂白废水中有机氯的去除率。

The comparison between the obtained EC50 values and toxicity data from the literature points out the good agreement between the BOD bottle test (Raphidocelis su.) and those of nine widely used test methods, i.e., Fathead minnow, Vibrio fi., Microtox, Polytox, Spriotox, Shk1, Activated sludge, Daphina ma. and Tetrahymena. In this study, log Kow values of narcosis Ι compounds (using the BOD bottle test and nine bioassays) were reported.

实验中选定DO观测终点所求得的毒性数据与其他物种进行回归分析，回归结果则皆呈现高度相关（R2值≧0.84），这可推论出藻类与其他物种的分析方法（不含Nitrosomonas）的致毒机制有很高的相关性，且可知本试验方法不仅敏感性高且与其他的物种且有良好的相关性可做为替代性试验。

Increasing the surface of plant fiber and the ratio of activated sludge to plant fiber can improve the degradation degree of plant fiber.

增加降解物的表面积和提高活性污泥与降解物的比值，有利于降解物的降解。

A new solid-liquid separation technology is proposed,which uses a suspended media filter bed to separate activated sludge and water.

1前言活性污泥法生物处理技术长期以来在生活污水以及工业废水处理中得到了广泛的应用。
