Papermaking wastewater pulp-water separation apparatus

Abstract

The invention discloses a papermaking wastewater paper-water separation apparatus, and belongs to the technical field of papermaking wastewater. The apparatus comprises a liquid pool, a flocculation tank and a separation device, the liquid pool is located beside the flocculation tank, the liquid pool is provided with a liquid pipeline extending into the flocculation tank, the flocculation tank isprovided with a liquid pipeline in overlapping fit with the separation device, the separation device comprises a sedimentation tank, a separation assembly and a collection assembly, the separation assembly is mounted at the top of the sedimentation tank, one end of the separation assembly extends to a position over the collection assembly, a defoaming assembly and a partition assembly are arrangedin the liquid pool, and the partition assembly is mounted in the liquid pool, and the defoaming assembly is in sliding fit with the top of the liquid pool. Two stretching members make a water filtering layer disengage from the sedimentation tank, a pulling motor drives a pulling wheel to rotate to make a pulling rope pull a sliding plate to move on a positioning plate, the sliding plate drives the water filtering layer to move into a collection box, and a plurality of air blowing nozzles blow paper pulp fibers on the water filtering layer into the collection box.

Description

technical field

[0001] The invention relates to the technical field of papermaking wastewater, in particular to a pulp-water separation device for papermaking wastewater. Background technique

[0002] At present, the water consumption of the papermaking industry is relatively large, generally 60-120 tons of water per ton of paper, and the wastewater concentration is high. There are many fine fibers in the papermaking wastewater, and the liquid volume accounts for about 5% of the treated water, and most of them are in the semi-suspended state. If the papermaking wastewater directly enters the regulating tank of the conventional treatment system and then settles, the sediment will decompose and stink, resulting in difficult wastewater treatment, complicated treatment process and high cost.
