Contact disinfecting pool for sewage treatment

Abstract

The invention discloses a contact disinfecting pool for sewage treatment. The contact disinfecting pool comprises a water inlet region, a mixed flow disinfecting region, a water outlet region and an automatic control center, wherein a water inlet gate is arranged between the water inlet region and the mixed flow disinfecting region; a water outlet gate is arranged between the mixed flow disinfecting region and the water outlet region; air flow stirring devices are uniformly arranged at the bottom of the mixed flow disinfecting region; the opening and the closing of the water inlet gate and thewater outlet gate are controlled by the automatic control center; the air flow stirring devices are connected with a blast blower through a gas conveying pipe; the blast blower is controlled by the automatic control center. The operation condition of the whole contact disinfection pool is intelligently managed through the automatic control center; the intelligent control on the contact disinfection work procedure is realized; the manual operation is not needed; the sewage treatment efficiency is ensured; the labor investment is reduced; the automation of the contact disinfection pool processing process is realized.

Description

technical field [0001] The invention relates to the technical field of urban sewage treatment, in particular to a contact disinfection tank for sewage treatment.
