Abstract

The invention relates to a wastewater sludge reduction treatment system which comprises a filtering device, an adjusting tank, an ultrasonic treatment tank, a buffer tank, a sludge acidification tank,a sedimentation tank, a sludge dehydration unit, a sludge drying unit and a sludge storage device. The adjusting tank comprises a first tank body, a biofilm culturing combined filler and an aerationdevice, wherein the biofilm culturing combined filler and the aeration device are arranged in the first tank body; an inlet of the filtering device is used for introducing sludge to be treated, an outlet of the filtering device is communicated with an inlet of the adjusting tank, an outlet of the adjusting tank is communicated with an inlet of the ultrasonic treatment tank, an outlet of the ultrasonic treatment tank is communicated with an inlet of the sludge acidification tank through the buffer tank, and an outlet of the sludge acidification tank is communicated with an inlet of the sludge dehydration unit through the sedimentation tank; an outlet of the sludge dehydration unit is communicated with an inlet of the sludge drying unit, and an outlet of the sludge drying unit is communicated with the sludge storage device. According to the technical scheme, efficient dehydration of the sludge can be achieved, and a good foundation is provided for subsequent treatment of the sludge.

Description

technical field [0001] The invention relates to the technical field of sludge treatment, in particular to a waste water sludge reduction treatment system. Background technique [0002] Sludge is a by-product produced in the process of purifying and treating sewage in sewage treatment plants. It is an extremely complex heterogeneous body, mainly composed of inorganic particles, bacterial cells, colloids and organic debris, rich in organic matter, nitrogen (N) , Phosphorus (P), Potassium (K) and trace elements are good organic fertilizers and have broad prospects for resource utilization. However, the high water content of sludge and a large amount of pollutants enriched in it restrict the further utilization of sludge, and also bring many problems to the treatment and disposal of sludge. Sludge without effective treatment and disposal can easily cause secondary pollution to groundwater and soil, posing a major threat to environmental safety and public health, and will also g...
