Embodiment Construction

[0015] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0016] Such as figure 1 The shown domestic sewage synchronous denitrification and phosphorus removal treatment equipment has anaerobic zone 1, anoxic zone 2, aerobic zone 3 and mixing zone 6 which enter sequentially after domestic sewage pretreatment. The bottom of the equipment is also equipped with Sedimentation zone 7 for sedimentation and discharge. The aerobic zone 3 is provided with an anion fiber membrane filter 4 through which the mixed liquid is discharged after aeration treatment and a chamfer 5 which can slow down the rising velocity of the water body. A two-phase drainage separator 8 is arranged above the mixing zone 6, and a hole is opened on th...

Abstract

The invention relates to treatment equipment for synchronous nitrogen and phosphorus removal of domestic sewage. The equipment comprises an anaerobic zone, an anoxic zone, an aerobic zone and a mixing zone that pretreated domestic sewage enters in order. The bottom of the equipment is also provided with a precipitation zone for precipitating and discharge of precipitates. With no need for pipeline connection, the treatment equipment for synchronous nitrogen and phosphorus removal of domestic sewage can solve the refluxing problem of a mixed solution to reach the standards of reclaimed water refluxing.

Description

technical field [0001] The invention relates to a treatment device for synchronous denitrification and phosphorus removal of domestic sewage which can solve the problem of mixed liquid reflux without pipeline connection and can reach the standard of reclaimed water reflux. Background technique [0002] There are nitrogen and phosphorus elements in domestic sewage. In order to remove nitrogen and phosphorus, many pipeline connections are needed in the prior art to solve the problem of mixed liquid backflow. The cost is high. At the same time, the treated domestic sewage often cannot reach the reclaimed water. reflow standard. Contents of the invention [0003] The technical problem to be solved by the present invention is: In order to solve the problems raised in the above-mentioned background technology, the present invention provides a treatment equipment for synchronous denitrification and phosphorus removal of domestic sewage, which can solve the problem of mixed liquid...
