用于污水处理厂中的污泥处理方法技术

一种用于污水处理厂中的污泥处理方法，其特征在于包括由顺次连接的Ｎ台螺杆膨化机构成的螺杆膨化机组，分别为自初级至末级，其中前级螺杆膨化机的出口与后级螺杆膨化机的入口相连，并且从初级至末级各级螺杆膨化机的出口压力逐级增加；其中，Ｎ为２以上的自然数；将含水率在４０％～８５％的污泥送入初级螺杆膨化机的入口，并使整个螺杆膨化机组同时工作，对污泥进行杀菌、破坏胶体和水分蒸发而干燥，直至污泥的含水率降低至５％～３５％时，将污泥从末级螺杆膨化机的出口排出。与现有技术相比，本发明专利技术的优点是工艺简单，处理方便，可工业化连续化处理，经过实验检测可知，经处理后的污泥其杀菌结果达到正常排标的要求。

Sludge treatment method for sewage treatment plant

A method for the treatment of sludge in the sewage treatment plant, which is characterized by comprising the screw extrusion unit N are sequentially connected by screw extrusion machine, respectively, from primary to final stage, the first stage screw extruder and the outlet level entrance extruder is connected, and the outlet pressure from the primary to the final all screw extrusion machine gradually increased; among them, N is a natural number more than 2; the water content in 40% ~ 85% of the entrance into the primary sludge extruder, and the screw extrusion unit at the same time, the sludge sterilization, destruction of colloids and water evaporation of water, until the sludge was reduced to from 5% to 35%, the sludge discharged from a final screw extruder outlet. Compared with the prior art, the invention has the advantages that the process is simple, the treatment is convenient, and the treatment can be industrialized and continuous. After the test, the result of the disinfection of the treated sludge reaches the requirement of normal calibration.
