But incineration of the electroplating sludge can get remarkable mass decreasing rates as more than 68% for original sludge and more than 30% for exsiccated sludge and high temperature can effectively reduce the lixiviation of heavy metals, but even the lowest lixiviation of Chromium is much higher than the national standard.

焚烧温度、时间和气氛对重金属的析出规律影响各不相同，Ni是唯一没有检测到析出率的重金属，Cr的析出率随着焚烧时间的增加而略有提高，Zn、Cu和Pb的析出率变化规律比较接近，析出率随着温度的增高而增大。

Furthermore, microscopic observation of biofilm and aerobic granules revealed much presence of protozoa and metazoa on the biofilm and suspended sludge,and this long food chain can contribute to the sludge reduction. Only 0.175 5 of sludge yields （MLSS/CODremoved） was obtained in the experiment, which was only about 50% of the conventional aerobic processes.

此外，镜检表明好氧颗粒污泥与生物膜均聚集大量的原生动物和后生动物，形成较长和较稳定的食物链，有利于污泥减量，运行过程中污泥产率（MLSS/CODremoved）为0.175 5，仅为普通好氧工艺的50%左右。

Finally it was found that the present of Oligochaetes not only brought better characteristics of the sludge such as good settleabilily, but also minished the membrane fouling greatly, and did not affect the effluent quality. And most important of all, in the case of almost no sludge production discharged, MLSS could be kept nearly 4000mg/L in more than 40 days when Oligochaete was present, which meant that there was no sludge production in the process.

同时，试验还发现大量蠕虫的存在，对出水水质的影响不大，但能够改善污泥特性，减缓动态膜污染，污泥浓度能自平衡于4000mg/L左右；并在近40天内，在没有排泥的情况下，无污泥量的增加，即实现了减量剩余污泥排放。

Up-flow velocity is one of the key factors affecting the granulation of sludge. Experiments results showed that there are two specific sludge mixing phenomena in ABR. One is roll suction and the other is purl trundle. They can weaken the need for up-flow velocity and accelerate sludge granulation in ABR.

通常情况下，上升流速是影响废水厌氧处理过程污泥颗粒化的重要因素之一，本研究中发现ABR具有卷吸和翻滚两种独特混合现象，这不仅削弱了反应器对水流上升速度的要求，而且大大加快了污泥颗粒化进程。

Sludge reduction technique is a new concept for disposal of residual sludge proposed based on the reutilization of residual sludge.

污泥是生物处理工艺的最终产物，活性污泥工艺的目的是在最大限度降低BOD5的同时减少污泥的产量。

The influence of the incorporation of electroplating sludge on the appearance and moulding granulation of the ceramsite calcined by the composite materials of electroplating sludge and seabeach sludge were investigated.

探索了电镀污泥掺量对电镀污泥与海滩淤泥复合烧制陶粒的外观质量和塑性造粒性能的影响规律，系统分析了高温烧制陶粒工艺对电镀污泥重金属铜、锌、镍、铬的固化效率。

The transportable and storable slurry were obtained by mixing sludge and coal, by using the technology of the coal water slurry, via the study on the slurry-forming property of the sludge and the coal. In order to solve the problem of the desiccation and transportation and feeding of the sludge in the incineration.

本文通过污泥与煤混合成浆的研究，利用水煤浆技术把污泥和煤混合成一种便于输送、贮存的浆体，以解决污泥焚烧中污泥的干燥、输送和给料问题。
