    摘要： A pair of rollers define between them a narrow gap which is supplied with sludge to be treated. The sludge is conveyed by one of the pair of rollers to a third roller in contact with the conveying roller. The third roller is spaced a short distance from a rotating drum carrier to which is applied a thin film of the sludge. The sludge is applied to the carrier by the formation of a sludge bulge, which is an accumulation of sludge, in the area defined by the carrier, the third roller, and the conveying roller. The drum carrier picks up the sludge from the sludge bulge forming a film of sludge whose thickness is limited by the spacing of the third roller from the carrier.

    摘要： Feed water is processed in an anaerobic digester. A solid-liquid separation device, for example a sludge screw thickener, treats a stream drawn from the digester in a recirculation loop. The solids portion is returned to the digester to increase the solids retention time and the TSS concentration in the digester. A liquid portion with less than 5% of the solids in the stream is removed and optionally treated further. The flow rate to the solid-liquid separation device is preferably greater than the influent flow rate. The solid-liquid separation device may receive digestate at a TSS concentration of 4% or more and return a solids portion having a TSS concentration of over 10%. The feed water is preferably one or more industrial waste streams having a COD concentration of 20,000 to 50,000 mg/L and a TSS concentration from 1-5%. The organic loading rate may be 10-12 kg/COD/m3/day.

    摘要翻译： 给水在厌氧消化池中进行处理。 固液分离装置，例如污泥螺杆增稠器，在循环回路中处理从蒸煮器抽出的物流。 固体部分返回到蒸煮器以增加蒸煮器中的固体滞留时间和TSS浓度。 除去流中具有小于固体的5％的液体部分，并进一步任选处理。 对固液分离装置的流量优选大于流入流量。 固液分离装置可以以4％或更高的TSS浓度接收消化物，并返回TSS浓度超过10％的固体部分。 给水优选为COD浓度为20,000〜50,000mg / L，TSS浓度为1-5％的一种以上的工业废弃物流。 有机负荷率可能为10-12 kg / COD / m3 /天。
