Embodiment 1

[0076] The sludge to be treated in a water plant in Shanghai is 10tDS / d. After the sludge is concentrated and precipitated in the concentration tank, the moisture content of the sludge is 98.5%. A 354 type screw stacker is used to dehydrate and reduce the sludge with high moisture content. It is connected to the sludge inlet of the screw stacker through a mud feed pump. The PAM agent concentration is prepared according to 1.5‰, and the agent is based on the absolute dry sludge quality. The final sludge moisture content is 73-75%. The sludge discharge end of the screw stacker is connected to the sludge inlet of the sludge conditioning reactor through a belt conveyor, and the conditioning agent dosing system is connected to the conditioning reactor through a pipeline. Reactor, 73-75% moisture content sludge and conditioner are conditioned and modified in the sludge conditioning reactor to improve the pressure resistance of the sludge and release the interstitial water, so that th...

Abstract

The invention discloses a sludge reduction and resourceful treatment system for a waterworks, and belongs to the technical field of general solid waste treatment. The system comprises a sludge primary dehydration module, a sludge conveying module, a sludge deep dehydration module and a sludge resource utilization module, the sludge primary dehydration module adopts a stacked screw machine or a centrifugal machine for dehydration; the sludge conveying module adopts a belt conveyor or a spiral conveyor for conveying; the sludge deep dehydration module comprises a sludge conditioning reactor, a conditioner adding system, an integrated sludge deep high-dryness intelligent decrement machine, a precision filter, a flushing water tank, a flushing water pump and an air compressor; the sludge resource utilization module comprises a scraper conveyor, a semi-dry sludge bin, a sludge dump truck and a firing-free brick making system. The system can effectively dehydrate high-water-content sludge of an existing waterworks, the size of the sludge is reduced, and pollution of the sludge to the environment is reduced; a firing-free brick making system is adopted for resourceful treatment, and the system saves energy consumption and is high in waste utilization rate.

Description

technical field [0001] The invention relates to the technical field of general solid waste treatment, in particular to a sludge reduction and resource utilization treatment system in a water plant. Background technique [0002] In recent years, with the development of industry and the improvement of people's living standards, the water supply business has achieved tremendous development. Under the current background, the number of water plants is increasing, and the water supply capacity is increasing day by day. Most water plants draw water from surface water sources such as rivers, lakes and reservoirs. The raw water undergoes processes such as flocculation, sedimentation, filtration and disinfection to remove impurities in the raw water and produce finished water that meets the sanitary standards for drinking water. In this series of water purification process, a large amount of sludge water and sludge are inevitably produced. [0003] Sludge water from the tap water pla...
