摘要： The invention relates to a method for clarification of raw green liquor in a sedimentation tank. According to the invention is a part of dregs separated in the sedimentation tank recirculated back into the inflow of raw green liquor, and preferably after passing the dregs through at least one turbulence generator (30, 31) that could break up larger dregs particles into smaller dregs particles, and thus create larger total surface on the dregs particles, improving sedimentation rate in the sedimentation tank. In a preferred embodiment is the recirculated dregs added into the flow of raw green liquor before a flocculant is added into the flow of raw green liquor and mixed recirculated dregs.

摘要： A settlement tank for use in a water treatment process. The settlement tank comprises a perimeter wall and a base to define a fluid holding region for holding fluid in the settlement tank. The settlement tank may comprise a scraper assembly comprising a scraper for scraping sludge from the base. A support connected to a central region of the base may comprise a mount rotatably mounting one end of the scraper to the support and positioned below an operational fluid level so as to be fully submerged during operation of the settlement tank. A drive mechanism for rotating the scraper assembly about the centre of the fluid holding region may be positioned outside the perimeter wall. An energy recovery device may be arranged to harness energy from fluid flow through an outlet formed in the perimeter wall. A launder trough via which fluid from the fluid holding region can exit the settlement tank may be constructed and arranged to define a walk way along which a person can walk. The launder trough may comprise a barrier wall with a plurality of holes below the operational fluid and scum level and through which fluid can flow to the launder trough.

摘要： Fluorescence in situ hybridizations were used to identify and determine the abundance of nitrifying bacteria and Anammox bacteria (recycling bacteria) in freshly settled sludge of biological nutrient removal (BNR) secondary clarifiers. An uneven distribution was observed for recycling bacteria in two BNR systems. Settling patterns suggest microcolony formation processes are sensitive to the internal recycle rate, which allow for rapid recycling bacteria microcolony growth by increasing circulation of flocs through the aeration and anoxic basins. Sludge containing high levels of recycling bacteria are selectively collected and separated from the remaining sludge, uncoupling the solids retention time (SRT) of the recycling bacteria from the wasting bacteria. Elevated recycling bacteria SRTs increase concentrations of nitrifying bacteria in the aeration basin and Anammox bacteria in the anoxic basin, improving nitrification and anaerobic ammonium oxidation. Uncoupling the SRT enhances aeration and/or anoxic basin utilization and reduces the overall hydraulic residence time.
摘要翻译：荧光原位杂交用于鉴定和确定生物营养物去除（BNR）二次澄清池新鲜沉淀的污泥中硝化细菌和厌氧菌（循环细菌）的丰度。观察到在两个BNR系统中回收细菌的不均匀分布。沉降模式表明微生物形成过程对内部循环利用率敏感，这允许通过增加通气和缺氧盆地的絮凝物的循环来快速回收细菌微菌落生长。选择性收集含有高水平回收细菌的污泥，并从剩余的污泥中分离出来，从循环细菌中分离回收细菌的固体滞留时间（SRT）。升高的循环细菌SRTs增加了无氧盆地曝气池和厌氧细菌中硝化细菌的浓度，改善了硝化和厌氧氨氧化。解耦SRT增强了曝气和/或缺氧池的利用率，并降低了整体的液压停留时间。

摘要： Apparatus for separating grit from liquid sewage while retaining organic solids in suspension. The apparatus includes a grit settling chamber, a grit storage chamber positioned below the settling chamber, and a rotating vertical shaft positioned centrally in the settling chamber. A propeller is rotatably mounted around the shaft. A conical partition extends transversely through an intermediate section of the settling chamber. Liquid sewage engages the lower part of settling chamber beneath the conical partition, and liquid separated from grit escapes from the upper part of settling-chamber above conical partition. The partition has a peripheral edge integrally mounted in fluid tight fashion to the peripheral wall of the settling chamber, and defines a central annular opening between the shaft and the partition to provide for upward flow of liquid from the lower subchamber to the upper subchamber. The propeller enables sustained rotational liquid sewage first fluid flow within the lower subchamber, inducing upward liquid second fluid flow from the lower subchamber through the partition annular opening and into the upper subchamber, and enables sustained rotational liquid third fluid flow within the upper subchamber for tangential or radial escape therefrom, wherein a fluid flow speed gradient is established between the third fluid flow and the first fluid flow.
