The invention provides a printing and
dyeing waste water treating
system and belongs to the technical field of
wastewater purification. The printing and
dyeing waste water treating
system solves the problem that the printing and
dyeing waste water treating effect is poor in the prior art. The printing and dyeing waste water treating
system comprises a flocculating tank, a
denitrification nitrogen removal treating device and a deep treating device. The flocculating tank comprises a
settling tank, a water inlet
pipe is arranged at the top of one side of the
settling tank, a water outlet
pipe is arranged at the top of the other side of the
settling tank, a settling device is arranged in the settling tank, a water inlet partition plate is vertically arranged in the settling tank, the lower side edge of the water inlet partition plate is fixedly connected with the wall of the settling tank through a supporting beam, the two vertical side edges of the water inlet partition plate are fixedly connected with the wall of the settling tank, the water inlet
pipe and the water outlet pipe are communicated with the parts, on the two sides of the water inlet partition plate, of an inner cavity of the settling tank respectively, the settling device is located on the part, between the water inlet partition plate and the water outlet pipe, of the supporting beam and located below an opening of the water outlet pipe, a funnel groove bottom is arranged at the bottom of the settling tank, and a flocculating net
assembly is arranged in the funnel groove bottom. The printing and dyeing waste water treating system has the
advantage of being good in printing and dyeing waste water treating effect.
