Turbidity of outflow reached the lowest level when ration of PAM towards sludge and water together equaled 1∶1. According to the orthogonal experiments, the sequence for four main factors of this technology influencing turbidity could be expressed as: poly-ferric chloride dosage, rotational speed of mechanical blender, activated sludge dosage, and PAM dosage.

同时，采用正交实验考察了不同因素对高效絮凝沉淀工艺的处理效果的影响程度，分析得出影响试验出水浑浊度的显著性顺序依次为：聚合氯化铁投加量＞机械絮凝搅拌转速＞活性污泥投加量＞PAM投加量。

The influence of the addition of chitosan, the pH, and the temperature was evaluated. And the properties of pancreatin separating with flocculation were compared with pancreatin separating with acetone.

探讨了壳聚糖用量、pH值、温度等因素对絮凝作用的影响，并比较了絮凝胰酶和丙酮胰酶性质的差异。

Through the measurement, it showed that the hot stability of the pancreatin separating with flocculation evidently strengthened, and the optimum temperature raised about 10*C.

测定絮凝沉淀胰酶滤液的酶活，结果滤液中酶活所占的比率很低，说明絮凝沉淀比较有效。

The flocculation mixer is flocculation pool mechanical rabble device , it is used for the waste water treatment mixing process mainly.

絮凝搅拌机是絮凝池机械搅拌的装置，它主要用于废水处理的搅拌过程。

The research analysed the current status and pollution treatment research review from municipal refuse output, waste physical component, hazards, heavy metal pollution. On the basis of overall understand of current treatment situation about main municipal refuse landfill site of Fujian province. By the simulated test, utilizing 7 kinds of physical adsorbents (zeolite, incineration ashes, slag, plant ash, charcoal, ochre, active carbon), 4 kinds of chemical flocculant FeSO_4, AlCl_3, FeCl_3, Al_2(SO_4_3, and 3 kinds of hyclrophytes, we carried through the pollution removing study of heavy metal in landfill leachate and discussed removing effect of different physical adsorbents, chemical flocculant and hyclrophytes.

并在对福建省主要城市生活垃圾的处理现状全面了解基础上，通过室内模拟试验，分别利用7种物理吸附剂(沸石、焚烧灰、炉灰、草木灰、木炭、赭石、活性炭)、4种化学絮凝剂FeSO_4、AlCl_3、FeCl_3、 Al_2(SO_4_3和3种水生植物进行垃圾渗滤液中重金属的污染去除研究，比较不同物理吸附剂、化学絮凝剂和水生植物对垃圾渗滤液重金属污染的去除效果，试图从中筛选出治理成本低和治理效果好的城市垃圾渗滤液重金属污染修复技术，供南方城市垃圾处理场推广应用。

First of all, four kinds of flocculating microbes with goodflocculating ability which were B-04、B-20、B-47 and M-03 were obtained by enrichment,first selection and reselection from three kinds of activated sludges .

首先从三种不同的活性污泥中通过富集、初筛、复筛，分离出了四种絮凝性能良好的絮凝菌株：B-04、B-20、B-47、M-03。

In the biological treatment, anaerobic biological treatment is used to reduce selenate ions and/or selenite ions presented in the raw wastewater to transfer to single insoluble selenium.

在生物法中，采用厌氧生物处理来降低原始废液中可溶的硒酸盐与亚硒酸盐，并转化为不溶性的单质硒，从而以不溶性单质硒的形式去除硒酸盐或亚硒酸盐；在絮凝沉淀法中，通常是向生物处理后的废水中加入一种金属盐，使该金属盐与可溶性硒反应并生成一种不溶性硒化合物，从而以不溶性硒化合物形式去除残留的可溶性硒；在过滤法中，将絮凝沉淀法中残留在废水中的不溶性硒去除，这样就能在不用大量化学药剂和不产生大量沉淀的情况下去除含硒废水中的可溶性硒。

The thermostability of MBF2 was good in the range of 25~40℃, but decreased obviously when temperature was higher than 40℃.

热稳定性实验显示，该絮凝剂在25~40℃范围内比较稳定，但在40℃以上时，絮凝活性显著下降。
