Problems solved by technology

[0002] At present, in some areas where paper-making factories are concentrated, a large amount of waste sludge will have no place to landfill, and it will take manpower and tool trucks to carry it, and the wastewater contained in the sludge will pollute the environment
And it needs a large piece of land to accumulate sludge, resulting in a waste of land resources

Embodiment Construction

[0012] like figure 1 As shown, the sludge is directly pumped from the sewage treatment tank into the sedimentation tank for sedimentation; after half an hour of sedimentation, it is put into clear water to make it a usable slurry with a certain concentration; it is then pumped into the intensive tank to adjust the concentration before printing; Concentration transmitter control, so that the concentration is controlled at 3%. After adjustment, it is sent to the forebay and mixed with good pulp to form a mixed pulp before going online. The pulp pump sends it to the online high-level box for papermaking. The concentration is 3%. This process makes the waste that originally flows into the river and needs to be treated and piled up become a good raw material for the sustainable development of the paper industry.

Abstract

A process for reclaiming the paper-making sludge includes such steps as directly pumping the sludge from sewage treating pool into depositing pool, depositing, filling clean water to become usable pulp, pumping it into intensity pool, regulating its concentration, mixing it with normal pulp, and making paper.

Description

Technical field: [0001] The invention relates to a treatment method for papermaking waste sludge, in particular to the technical field of sludge reuse. Background technique: [0002] At present, in some areas where paper factories are concentrated, a large amount of waste sludge has no place to landfill, and it takes manpower and tool trucks to carry it, and the wastewater contained in the sludge pollutes the environment. In addition, a large piece of land is required to accumulate sludge, resulting in a waste of land resources. How to solve papermaking sludge has become a technical problem that has plagued the papermaking industry for a long time. Invention content: [0003] The purpose of the present invention is to overcome the above disadvantages and provide a papermaking sludge recycling process that can truly achieve zero discharge of sludge, save costs and turn waste into treasure. [0004] The present invention is realized through the following technical scheme: ...
