Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of wastewater purification and relates to a printing and dyeing wastewater treatment system. Background technique [0002] The amount of waste water produced by my country's textile industry is large and its concentration is high. It is one of the industrial pollution sources that pose a serious threat to water environmental pollution. Among textile industry wastewater, printing and dyeing wastewater is the most polluted; the treatment technologies for printing and dyeing wastewater mainly include chemical methods, mass transfer methods, heat treatment methods, and biological methods; printing and dyeing wastewater contains a wide variety of chemical substances with strong pollution, including dyes , additives, oil agents, acid and alkali substances, fiber impurities and inorganic compounds and other components, and the amount of wastewater is also particularly large, high chroma, high COD, and many impuriti...
