Bioflocculants, having good flocculating activity, are the metabolic products of the microorganism, which are safe, non-toxic and can be biodegraded easily.

微生物絮凝剂是一类由微生物产生并分泌到细胞外具有絮凝活性的生物活性物质，具有良好的絮凝沉淀性能，安全、无毒，易于生物降解。

The results show, Sodium hexametaphosphate is the best disperse, purified and decolored reagent, which can disperse attapulgite into nano-class crystal by absorption, electrochemistry and chemical treatment, separate other mineral impurity effectively, react with main colored ion into phosphate deposition achieving decolor aim.

研究结果表明，六偏磷酸钠是凹土矿良好的分散提纯和脱色剂，它通过吸附、电化学作用和化学反应使凹土晶体充分分散为纳米级晶体颗粒，使包裹其中的其他矿物杂质有效分离，并与凹土中的主要带色离子生成磷酸盐沉淀使凹土色泽变白。

The result indicated that the relative best technological scheme were:① microwave deodorized conditions was 800 W×2450 MHz×3 S×3~5 min×9~10 W/g;②dropped organic flocculation agent 0 to 250×10^(-6) or 50×10^(-6) to precipitation protein;③ spray drying-air dry (20~40℃ as pulp temperature, 1.0mm as nozzle caliber; 30~40℃×24 h as air dry temperature).

结果表明，较佳的工艺方案是：在800W×2450MHz×3S×3~5min×9~10W/g微波脱臭；滴加250×10^(-6)或50×10^(-6)的有机絮凝剂D沉淀蛋白；喷雾－风干（浆料温度为20~40℃，喷嘴口径1.0mm；风干温度为30~40℃×24h）。

That's where water treatment comes into the picture. A water treatment plant purifies the water by adding coagulant that precipitate impurities and particles in the water, allowing it to be flocculated and filtered. Chlorine is then added as a disinfectant before it can properly be called "tap water".

滤水厂将收集到的原水净化，一般都是将凝集剂加入原水中，使混杂於水中的悬浮物凝集成较大的粒块，再经过沉淀、过滤的净化过程，最后加入氯气消毒才能成为「滤水」。

Results suggest that, firstly, when inorganic flocculant Al_2(SO_4_3, FeCl_3 or PAC is added into surfactant micellar solution, surfactant is flocculated in micellar form.

结果表明，1向表面活性剂胶束溶液中加入无机混凝剂Al_2(SO_4_3、FeCl_3或PAC，表面活性剂以胶束形态被混凝沉淀。

In fact, the coagulating mechanism was surface chelating and surface sedimentation. It was said that adsorption was before hydrolysis, then the hydrolysis and sedimentation reaction of the polynuclear hydroxy complexes took place on the adsorption surface, at the same time they counteracted the electric charge of the colloids and suspended substances then adsorbed and bridged the flocculates.

其混凝机理实际上是表面络合及表面沉淀过程，即絮凝剂投入水体后，其最佳混凝形态及其聚集体在一定时间内具有稳定性而保持其原有形态，并很快吸附在颗粒物表面，吸附过程先于水解过程，因带电荷及分子量较高而同时发挥电中和及吸附架桥作用。
