Abstract

The invention provides a graded input type slush processing method and a device. The invention is mainly characterized in that the method is a sludge and sewage processing method involving a graded input type sludge preparation system and a plug-flow type multi-stage slush processing container. The graded input type sludge preparation system has at least two water-inlet and sludge-level control devices communicated with space of the slush processing container. Slush is input into the space of the multi-stage slush processing container successively from front to back, sludge is accumulated step by step, and the slush undergoes deposition, concentration and digestion treatments in the slush processing space. By the method and the device, a slush input system in the sludge processing system is optimized, and interference and mixing of subsequently input sludge with stable sludge are avoided. The method and the device are beneficial to stabilizing treatment of sludge and guarantee working stability of the process system.

Description

technical field [0001] The invention relates to a method and device for treating sewage and sludge. Background technique [0002] Domestic sewage contains mud, sand and impurities, especially the mud, sand and sediment in the primary sedimentation tank and dung water. This kind of mud, sand and sediment are basically substances with relatively stable physical states. For sludge stabilization treatment, the treatment of degradable sludge is to separate the stable substances from the unstable substances and treat them with suitable technology. According to the principle of sludge balance and absorption, impurities such as mud, sand, and sediment will accumulate over time, while degradable substances have a state limit, and the increment of degradable substances will gradually slow down and tend to zero growth. Therefore, for sludge, manure, etc. The treatment method is to separate different components, clear and discharge mud, sand, sediment and other substances, and store an...
