Municipal sewage treatment device

Abstract

The invention discloses a municipal sewage treatment device which comprises a mixing tank, a flocculation tank and a settling tank,wherein the mixing tank, the flocculation tank and the settling tankare integrally connected and communicated sequentially from front to back according to the technological process, a water inlet pipe is arranged at the front end of the mixing tank, a medical adding pipe is connected to the water inlet pipe, baffles are uniformly and vertically arranged in the mixing tank, a water dispersing pipe is arranged at the top end of the flocculation tank, a stirring mechanism is arranged in the flocculation tank, a water distributing hole is formed in the bottom wall of the right side of the flocculation tank and communicated with the settling tank, and a central pipe, a central pipe hopper, a spiral baffle, a collection hopper and a water outlet are arranged on the settling tank. According to the municipal sewage treatment device, the integrally connected mixingtank, the flocculation tank and the settling tank are arranged, so that the processed water quality and the volume load are improved greatly, the pollutant removal efficiency and the purifying capacity are high, at the same time, the equipment structure is compact, the occupied area is small, and the device is suitable for the small-scale sewage treatment site.

Description

technical field [0001] The invention relates to the field of sewage treatment equipment, in particular to a municipal sewage treatment device.
