Industrial papermaking wastewater treatment device

Abstract

The invention discloses an industrial papermaking wastewater treatment device which comprises an upper supporting assembly and a lower supporting assembly. The upper supporting assembly is connected with a screen assembly, and the two sides of the screen assembly are further rotationally connected with vibration assemblies. Driving assemblies are connected to the left side and the right side of the upper supporting assembly correspondingly, a connecting assembly is further fixedly installed in the middle of the front side of the upper supporting assembly, and a rotary spraying head is connected to the side, close to the screen assembly, of the connecting assembly. The lower supporting assembly is fixedly connected with a collecting box body, and the collecting box body communicates with the connecting assembly through a guide pipe. According to the device, in order to prevent blockage caused by concentrated accumulation of fibers in wastewater on the screen assembly, the wastewater is uniformly sprayed on the screen assembly to be filtered and sieved through the arrangement of the connecting assembly and the rotary spraying head, and then the preliminarily filtered wastewater is subjected to secondary filtration through the arrangement of the connecting assembly and the screen assembly; the filtering effect of the device can be further improved.

Description

technical field [0001] The invention belongs to the technical field of wastewater treatment equipment, and in particular relates to an industrial papermaking wastewater treatment device. Background technique [0002] With the continuous development of the paper industry and the general improvement of people's awareness of environmental protection, more and more attention has been paid to the treatment of waste water produced by the paper industry. The waste water of the paper industry contains a large amount of fibrous substances. If it is directly discharged to the outside world, it will not only cause It causes environmental pollution and waste of raw materials. [0003] When the existing primary filtration device for papermaking wastewater performs preliminary filtration of the wastewater, the papermaking wastewater contains a large amount of thick and thin fibers to form suspended impurities. The problems that often occur in the existing equipment are as follows: [000...

AI Technical Summary

Problems solved by technology

[0004] 1. Most of the filtration treatment is a single filtration, so that the fine fibers are directly discharged through the filter mechanism, resulting in the treated wastewater not meeting the discharge standard

[0005] 2. After a long period of filtration, the fiber impurities in the wastewater are easy to accumulate on the filter screen, which is easy to block the filter mechanism, which is not conducive to the subsequent sewage treatment operation and affects the treatment of papermaking wastewater
