Novel sludge wastewater treatment system and method

Abstract

The invention provides a novel sludge wastewater treatment system and method. The treatment system comprises a feeding device, a medicament feeding device, a treatment device and a filtering device, wherein the feeding device comprises a material storage groove, a feeding groove and a high-pressure tank, which are communicated in sequence; the feeding groove is internally provided with a de-foaming device; the medicament feeding device comprises a medicament stirring groove; the treatment device comprises an ozone machine, a treatment groove and an ozone damaging device, which are communicatedin sequence; the filtering device comprises a sedimentation tank, a filtering machine and a clean water tank; the treatment method comprises the following steps: inputting a medicament into the feeding rogroove; feeding sludge wastewater into the treatment groove through the material storage groove and the feeding groove in sequence; starting the ozone machine and the de-foaming device; after treating materials through ozone for 1 to 2 h, transferring the sludge wastewater in the system into the sedimentation tank and precipitating; after precipitating the sludge wastewater through the sedimentation tank, conveying the sludge wastewater into the filtering device; after dehydrating, transferring dry sludge into a storage yard and transferring clean water into the clean water tank. The novel sludge wastewater treatment system and method aim at treating the sludge wastewater and solving the problems in the prior art that the treatment efficiency of a sludge wastewater treatment process is low, the cost is high, a flow is complicated, the working amount of maintaining and overhauling is great and the like are solved.

Description

technical field [0001] The invention relates to the field of wastewater treatment, in particular to a novel sludge wastewater treatment system and method. Background technique [0002] Sewage treatment plant sludge refers to the solid, semi-solid and liquid waste produced by sewage treatment, which contains a large amount of organic matter, heavy metals, pathogenic bacteria and pathogenic bacteria, etc. If it is discharged without treatment, it will cause serious pollution to the environment. For example, the wastewater produced in the pulping and papermaking process contains a large amount of organic components such as cellulose, hemicellulose, and fine fibers that are easily utilized by microorganisms. These substances are one of the main contributors to the COD and BOD of wastewater. The solid residues produced in the pulp and paper production process are large in quantity and various in variety. At present, a large amount of sludge produced in the paper industry is disca...
