Description

Sludge dewatering machine for sewage treatment

Technical Field

The utility model relates to a sewage treatment technical field specifically is a sludge dewaterer for sewage treatment.

Background

Sludge dewatering for sewage treatment is a sludge treatment method which removes water from fluid primary, concentrated or digested sludge and converts the sludge into semi-solid or solid sludge blocks. The sludge generated by sewage treatment has higher water content, and because of the characteristic of combining water and sludge particles, the mechanical method has certain limitation on removal, and the organic matter content and the ash content in the sludge, particularly the addition amount of a flocculating agent, have important influence on the final solid content. In general, solids contents of 20% to 30% can be achieved by mechanical dewatering, the sludge formed also being referred to as a cake. The water content of the sludge cake is still high, the sludge cake has fluid properties, and the disposal difficulty and cost of the sludge cake are still high, so that further reduction is necessary. After dewatering, the water content of the sludge can be reduced to fifty-five percent to eighty percent, depending on the properties of the sludge and the sediments and the efficiency of the dewatering equipment. The further dehydration of the sludge is called sludge drying, and the moisture content of the dried sludge is less than ten percent. The dehydration method mainly comprises a natural drying method, a mechanical dehydration method and a granulation method. The natural drying method and the mechanical dehydration method are suitable for sewage sludge. The granulation method is suitable for coagulating sedimentation sludge.
