Energy-saving and environment-friendly industrial sewage staged treatment device

Abstract

The invention discloses an energy-saving and environment-friendly industrial sewage staged treatment device in the technical field of industrial sewage filtration and purification. The device comprises a tank body, wherein an active carbon filter screen and a filter screen I are arranged in the middle of an inner cavity of the tank body; a filter stand is arranged at the top of an inner wall on the left side of the tank body; a liquid delivery pipe is adhered to an outer wall on the right side of a partition; a stirring motor is arranged at the top of a cover plate; a cleaning disc is arrangedon an outer wall at the top of a stirring shaft; a top wall of the inner cavity on the right side of the tank body is connected with a filter screen II; according to the device, preliminary filteringis performed by the filter screen I; many impurities in sewage are effectively reduced; the active carbon filter screen absorbs and purifies the impurities; at the same time, collecting holes in collecting plates collect and filter flocculent impurities in treated water; the cleaning disc is rotated to drive brush rolls to clean the bottom of the filter screen II; a filtering effect of the filterscreen II is improved; and the influence of blocking of the filter screen II on a filtering effect and discharge efficiency of the treated water is avoided.

Description

technical field [0001] The invention relates to the technical field of industrial sewage filtration and purification, in particular to an energy-saving and environment-friendly industrial sewage classification treatment device. Background technique [0002] Textile printing and dyeing wastewater is wastewater discharged from printing and dyeing factories that mainly process cotton, hemp, chemical fibers and their blended products. The amount of printing and dyeing wastewater is relatively large, and solid-liquid classification equipment is also needed in the textile and printing and dyeing industries. In order to solidify the sewage However, the waste liquid after solid-liquid separation treatment cannot be treated cleanly, and it will still cause certain pollution when discharged into the surrounding environment. Therefore, we propose an energy-saving and environmentally friendly industrial sewage classification treatment device. Contents of the invention [0003] The obj...
