1. Sludge digestion Sludge digestion includes anaerobic digestion and aerobic digestion. Anaerobic digestion is a process in which organic matter in sludge is degraded and stabilized by anaerobic microorganisms under anaerobic conditions. The aerobic digestion of sludge is similar to the activated sludge process. It is developed on the basis of the delayed aeration activated sludge method. Its purpose is to stabilize sludge, reduce the harm of sludge to the environment and soil, and reduce pollution. Final throughput of the mud.

2. Sludge composting (biological drying) Sludge composting, also known as sludge biological drying, is a process of using aerobic microorganisms in sludge for aerobic fermentation. It is a self-heating process that can eliminate pathogens And produce a substance similar to humus, which can be generally divided into two types: sludge composting alone and sludge and garbage mixed composting. 3. Sludge drying Sludge drying is divided into two modes: natural drying and thermal drying of sludge; it refers to the process of removing most of the water content from sludge through percolation or evaporation. The natural drying of sludge is generally realized through self-evaporation facilities such as sludge drying fields (beds); the thermal drying of sludge is to use artificial energy as a heat source, and use industrial equipment to remove moisture from wet sludge based on drying principles. the goal of.

Twesix dry sludge low-temperature drying treatment equipment uses air energy and waste gas to incinerate waste heat, and adopts low-temperature waste heat drying method, which can greatly reduce the demand for energy in the drying process, and can also use other waste heat as a heat source to fully utilize the heat source.
