Problems solved by technology

[0004] In order to avoid the influence of activated sludge on the detection of chemical oxygen demand of sewage, it is generally tested in the secondary sedimentation tank. If the chemical oxygen demand is not up to standard, it cannot be discharged, and it must be returned to the aeration tank for treatment, so that Affect normal sewage treatment and reduce the efficiency of sewage treatment

Abstract

The invention discloses a printing and dyeing textile sewage treatment system, which belongs to the field of sewage treatment equipment and solves the problems that when treated sewage is unqualifiedthrough detection, the sewage needs to return into an aeration tank to be treated again, so that the normal sewage treatment is influenced; the sewage treatment efficiency is reduced. The printing anddyeing textile sewage treatment system is mainly characterized by sequentially comprising a sewage storage pool, a filtering pool, a primary precipitation pool, an aeration pool and a secondary precipitation pool, wherein the secondary precipitation pool is connected with a membrane bioreactor. The printing and dyeing textile sewage treatment system has the advantages that the structure is reasonable; sewage which is still unqualified after the treatment is discharged into the membrane bioreactor to be treated, so that the normal sewage treatment is not influenced; the goal of improving the sewage treatment efficiency is improved.

Description

technical field [0001] The invention relates to a sewage treatment device, more specifically, it relates to a printing and dyeing textile sewage treatment system. Background technique [0002] With the development of textile printing and dyeing industry, the impact of printing and dyeing wastewater on the environment is increasing, and the research and development achievements of printing and dyeing industrial wastewater treatment are also being continuously transformed and applied. [0003] At present, the Chinese invention patent with the notification number CN104973722B discloses a printing and dyeing textile sewage treatment process, which is used in the sewage treatment system and includes a grid, a water collection tank, a primary aeration tank, a secondary aeration tank, a coagulation sedimentation tank and a sedimentation tank. tower, the sewage is processed sequentially through the grille, sump, primary aeration tank, secondary aeration tank, coagulation sedimentati...
