An industrial wastewater treatment device

Abstract

The invention discloses an industrial wastewater treatment device. The industrial wastewater treatment device comprises a wastewater pool, a discharging pipe, a soft thorn collecting mechanism, a settling tank, a ventilation pipe, a valve and a negative pressure pump, wherein the discharging pipe is arranged on the side of the top end of the wastewater pool; one end of the discharging pipe is communicated with the wastewater pool; the other end of the discharging pipe is communicated with the soft thorn collecting mechanism positioned at the diagonal lower part; the setting tank is arranged onthe other side, opposite to the discharging pope, of the soft thorn collecting mechanism and is mechanically connected with the soft thorn collecting mechanism; the mounting position of the setting tank is lower than the soft thorn collecting mechanism; the setting tank is mechanically connected with the negative pressure pump through a ventilation pipe; the valve is arranged at the middle position of the ventilation pipe. According to the industrial wastewater treatment device disclosed by the invention, bubbles bonded with staple fibers are automatically collected and pierced, the stable fibers are bonded in large area and fishing for multiple times is avoided, so that labor intensity is reduced.

Description

technical field [0001] The invention relates to the field of industrial wastewater treatment, in particular to an industrial wastewater treatment device. Background technique [0002] Paper mills will have a large amount of wastewater in the process of pulping, modulation, and papermaking. These wastewater will be combined with physical, chemical and biochemical methods, and the suspended solids in the wastewater will be removed by coagulation and sedimentation. After decolorization by chemical methods, the flotation method will be used. When recovering fibrous fixed substances in white water, when the flotation method is used to recover fibrous solids in white water, the suspended matter in the water, such as segmented fibers, adheres to the air bubbles, suspends on the surface of the water body with the air bubbles, and then uses the net bag to salvage. The quantity is large and the number of times of salvage is frequent, and the short fiber obtained after recycling does n...
