Description

technical field [0001] Type the technical field description paragraph here. Background technique [0002] Sludge is the solid precipitated organic matter and microbial bacteria micelles produced in the sewage treatment process. It is a product after sewage treatment. It is an extremely complex heterogeneous body composed of oxins and toxic heavy metals such as arsenic, copper, mercury, and chromium, and even toxic, odorous, and turbid harmful substances such as radionuclides that are difficult to degrade. The main characteristics of sludge are high water content (up to 99%), high content of organic matter, easy to rot and smell, and the particles are finer, the specific gravity is smaller, and it is in a colloidal liquid state. It is a thick substance between liquid and solid, which can be transported by pump, but it is difficult to separate solid and liquid by sedimentation. Sludge has high moisture content and large volume, which brings difficulties to stacking and trans...
