Advanced sludge treatment equipment and using method thereof

Abstract

The invention belongs to the technical field of sludge treatment, and particularly relates to advanced sludge treatment equipment. The equipment comprises a solar power supply mechanism, a sludge tank, a sludge pump, a belt type sludge concentration and dehydration integrated machine, a dosing device, a dosing pump, an inclined shaftless conveyor, a sludge modification mixer, a modifier dosing device, a continuous sludge deep dehydration squeezer, an inclined shaft conveyor, a cleaning pump and a stainless steel mesh filter; the output end of the solar power supply mechanism is electrically connected to the sludge pump, the belt type sludge concentration and dehydration integrated machine, the dosing pump, the inclined shaftless conveyor, the sludge modification mixer, the continuous sludge deep dehydration squeezer, the inclined shaft conveyor and the cleaning pump separately; and the input end of the belt type sludge concentration and dehydration integrated machine respectively communicates with the sludge pump and the dosing pump through two branches, an inlet of the sludge pump communicates with the sludge tank, an inlet of the dosing pump communicates with the dosing device, and an inlet of the dosing device communicates with a plant area water supply system. The invention further relates to a using method of the advanced sludge treatment equipment.

Description

technical field [0001] The invention belongs to the technical field of sludge treatment, and in particular relates to sludge advanced treatment equipment and a use method thereof. Background technique [0002] The most content in the sludge is water, which can reach 95% to 99.5% of the total mass. Removing the water in it will greatly reduce the volume of the sludge, but studies have shown that the solid matter in the sludge is mainly humus. Water-based negatively charged colloidal particles have a strong affinity with water, a large specific resistance, and poor dehydration performance, which brings many problems to handling and disposal. Therefore, before mechanical dehydration of sludge, conditioning agents are usually required to change the surface properties and components of sludge particles, destroy the colloidal structure of sludge, reduce the affinity with water, and improve dewatering performance. At present, the sludge needs to be treated to a water content below...

AI Technical Summary

Problems solved by technology

At present, the sludge needs to be treated to a water content below 60% before it can be landfilled. However, the existing sludge treatment equipment requires high cost and complicated and difficult process to reduce the water content of the sludge to below 60%. Big

[0003] Not only that, there will be a lot of energy consumption in the sludge treatment process, the most important thing is electric energy, and some rural locations are relatively remote, and it is difficult to supply power during the sludge treatment process. Due to the small amount of treatment, if the power supply is re-powered separately, the cost will be relatively high. high
