Organic and compound cation garrulous coagulates the agent is to use chemical law compound a kind of new-style cation garrulous coagulates agent, belong to domestic and international initiate, with other and groovy drug photograph comparing has 5 big advantages: The photograph such as aluminium of as aggregate as commonly used drug chloridize, aggregate and vitriolic iron, vitriolic aluminium is compared, coagulate with garrulous of polypropylene acyl amine the agent is used jointly, medical dose is little, reduce useless water treatment to expend about 20 ％ thereby, 30 ％; Effect of processing liquid waste is good, garrulous is round settling speed is fast, make liquid waste can second birth is used, managing water natural resources; Its garrulous group is sedimentary filterability can be good, slime can reclaim inside entire plant, namely energy-saving be helpful for protecting an environment again; Corrode to equipment small; Have muti_function, have agglomeration effect already, again garrulous coagulates action and the action that aid filter, can serve as filter aid.内容来自www.ch-water.com

有机复合阳离子絮凝(使液体中悬浮微粒集聚变大或形成絮团，从而加快粒子聚沉，达到固-液分离的过程)剂是利用化学法合成的一种新型阳离子絮凝(使液体中悬浮微粒集聚变大或形成絮团，从而加快粒子聚沉，达到固-液分离的过程)剂，属国内外首创，与其他常规药剂相比具有五大优点：与常用药剂聚合氯化铝、聚合硫酸铁、硫酸铝等相比，与聚丙烯酰胺类絮凝(使液体中悬浮微粒集聚变大或形成絮团，从而加快粒子聚沉，达到固-液分离的过程)剂联合使用，药剂量少，从而降低废水处理(通过物化方法去除水中一些物质的过程)费约20％—30％；处理废水效果好，絮团沉降速度快，使废水能再生利用，节约水资源；其絮团沉渣过滤性能好，煤泥可全部厂内回收，即节能又有利于保护环境；对设备腐蚀小；具有多功能，既有凝聚作用，又有絮凝(使液体中悬浮微粒集聚变大或形成絮团，从而加快粒子聚沉，达到固-液分离的过程)作用和助滤作用，可作为助滤剂。

The up-flow zone and down-flow zone are fit together, which make the structure of reactor much compacter, and the less area taken Three-phase separator replaces the secondary settling tank, it has detter capacity and less sludge, frees of phenomena of sludge bulge.

5The distribution patterns of rare earth element compositions in the hydrothermal components are similar to that of pacific seawater. This infers the complex and significant interactions of hydrothermal fluid with surrounding seawater during its diffusing process. Dissolved trace metals in the hydrothermal fluid can be removed by settling terrigenous or biogenic particulates and precipitated quickly from the hydrothermal plume round the vent. On the other hand, hydrothermal particulates would also scavenge some elements from the seawater to coprecipitate into the sediments.

5岩芯沉积物中热液源组分携带的稀土元素组成具有类似海水的分布模式，反映了热液流体喷出海底后与其它物源物质之间的复杂的相互作用：一方面大量生物和陆源碎屑物质的快速沉积导致溶解态的热液源物质被快速清扫，无法向外扩散，快速堆积在热液喷口附近；另一方面，随热液羽状体向外扩散的颗粒态热液源物质也清扫海水中的元素共同进入沉积物。

"If you wanted a meeting that all know about," Eclair asked, settling himself on a stool,"then why are we hiding in a closet?"

The sludge settling characteristic is satisfying with SV varying from 22 to 30 and SVI varying from 58 to 80ml/g.The sludge bulking problem has been avoided successfully. The excess sludge can be thickened to 3%-4 %. The alkalinity remains equilibrious between the nitrification and denitrification in SBR-BAF system. The COD and TP loading of SBR are 2.08kgCOD/kgMLSS·d and 41.68gTP/kgMLSS·d, respectively. The NH4+-N loading of BAF is 1.16kgNH_4~+-N/m~3.d. The total HRT is about 10 hours which is only about half of suspended growth process for simultaneous phosphorous and nitrogen removal. Under the above mentioned high loadings and short HRT, the mean removal efficiency of COD, TP, NH4+-N, TN is 96%, 98%, 93%, and 84%, respectively. The mean effluent concentration of COD, TP, NH4+-N, TN, SS is 20mg/L, 0.23 mg/L, 3.24 mg/L, 7.68 mg/L, 5 mg/L respectively, which means every index can meet the first class of Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant.

最后，以上述最佳运行参数控制SBR-BAF系统运行，长期运行结果表明：系统中悬浮污泥的絮凝、沉降性能良好，SV值为22~30，SVI值为58~80，不再有污泥膨胀之虞，而且可以对剩余污泥进行重力浓缩，浓缩后污泥浓度可以达到3~4%；短程硝化和反硝化使得系统可以维持碱度平衡，无需额外补充碱度；系统在高负荷(SBR反应器COD负荷为2.08kgCOD/kgMLSS.d，TP负荷为41.68gTP/kgMLSS.d，BAF反应器NH4+-N负荷为1.16kgNH_4~+-N/m~3.d)、低水力停留时间(SBR反应器9h，BAF反应器1h，总计10h，约为同步脱氮除磷悬浮污泥工艺的一半)下稳定高效运行，对COD(不计BAF加入的外碳源)、TP、NH_4~+-N、TN的平均去除率为96%、98%、93%、84%，出水COD、TP、NH4+-N、TN、SS的平均浓度为20mg/L、0.23 mg/L、3.24 mg/L、7.68 mg/L、5 mg/L，各项水质指标均达到《城镇污水处理厂污染物排放标准》(GB 18918-2002 )一级标准的A标准的要求。
