Description

Technical Field

[0001] The utility model relates to the technical field of sludge treatment, in particular to an environmentally friendly biological sludge and sewage treatment device. Background Art

[0002] Sludge is the accumulated solid sediment separated from various types of water, wet or mixed with liquid components, and is the product of natural or artificial treatment processes. Municipal sewage, water supply plants and industrial wastewater treatment plants continuously discharge a large amount of sludge during the production process, which requires further treatment. Sludge treatment is the process of reducing, stabilizing and harmless treatment of sludge. The higher the degree of sewage treatment, the more sludge residue will be produced and need to be treated. Unless land treatment or sewage ponds are used to treat sewage, general sewage treatment plants must have sludge treatment facilities. For modern sewage treatment plants, sludge treatment and disposal has become the most complex and expensive part of sewage treatment system operation.

[0003] The existing sludge treatment is to add flocculants and other chemical agents into the sewage to separate the sludge and sewage, and then squeeze the sludge to squeeze out the water inside and squeeze it into blocks to complete the treatment. However, after the sludge and sewage are separated, the sewage needs to be discharged from the sedimentation tank and the sludge needs to be fished out and squeezed, which is not only difficult to operate, but also time-consuming and labor-intensive.
