摘要： A sludge concentrating apparatus comprising a sludge tank for storing sludge and a filter cloth having a shape of endless belt which turns between upper and lower rollers, further comprising filtering means of which at least the lowermost of rollers is immersed in the sludge, washing means of the filter cloth, and a filtrate chamber having a filtrate introducing port in contact with the filter cloth and a weir, wherein a sludge distributing tank serving as sludge introducing means into the sludge tank is provided near the upper end of the filtrate introducing port, and a concetrated sludge discharge tank serving as concertrated sludge introducing means with the filter cloth in between; said sludge concentrating apparatus further comprising coagulant adding means for adding an acid, and a flow adjustment device serving as a sludge uniform feeding means which feeds sludge fed into the sludge tank uniformly in the width direction of the filter cloth. It is thus possible to efficiently concentrate sludge produced in a sewage disposal plant in a large quantity without depending upon properties of sludge.
摘要翻译：一种污泥浓缩装置，包括用于储存污泥的污泥槽和具有在上下辊之间转动的环形带形状的滤布，还包括过滤装置，至少最下层的辊浸入污泥中，洗涤装置滤布和具有与滤布接触的滤液引入口的滤液室和堰，其中，在滤液引入口的上端附近设置有作为污泥引入装置的污泥分配槽，一个浓缩的污泥排放槽，用作一个混合污泥引入装置，其间装有滤布; 所述污泥浓缩装置还包括用于添加酸的凝结剂添加装置，以及用作污泥均匀进料装置的流量调节装置，其在滤布的宽度方向上均匀地供给污泥槽中的污泥。因此，可以有效地浓缩污水处理厂中产生的污泥，而不依赖于污泥的性质。

摘要： A sludge concentrating device comprising a sludge tank storing sludge, a filtering means having an endless belt filter cloth revolving around upper and lower rollers with at least the lowermost roller immersed in the sludge, a filter cloth washing means, a filtrate chamber having a filtrate inlet close to the filter cloth and a weir, a sludge distributing tank serving as a means for introducing sludge into the sludge tank and disposed in the vicinity of the upper end of the filtrate inlet, and a concentrated sludge discharge tank serving as means for discharging concentrated sludge from the sludge tank and disposed in a position substantially opposed to the sludge introducing means with the filter cloth interposed therebetween, wherein the device further comprises a flocculant adding means for adding a flocculant to the sludge fed to the sludge tank, an acid adding means for adding an acid, and a rectifier serving as a uniform sludge feeding means for feeding sludge into the sludge tank uniformly widthwise of the filter cloth. Thus, the sludge produced in a sewage disposal plant can be concentrated in large quantities and efficiently without depending on its properties.
