A rain sewage pipe network intelligent splitting device based on ammonia nitrogen concentration

Abstract

The invention discloses a rain sewage pipe network intelligent splitting device based on ammonia nitrogen concentration, which comprises a control box, a sewage pump, a liquid level gauge, an ammonianitrogen concentration sensor, an intelligent control system, and an intelligent control system for controlling the start and stop of the sewage pump. At least two liquid level data and one ammonia nitrogen concentration data are preset in that intelligent control system, which are mar as the starting liquid level, the close liquid level and the opening / closing concentration respectively, and theclosing liquid level is higher than the top elevation of the sewage pump; When the liquid level measured by the liquid level gauge is higher than the starting liquid level and the ammonia nitrogen concentration measured by the ammonia nitrogen concentration sensor is higher than the on-off concentration, the sewage pump is turned on. If the ammonia nitrogen concentration measured by the ammonia nitrogen concentration sensor is smaller than the on-off concentration, or the liquid level measured by the level gauge is lower than the off-off liquid level, the sewage pump shall be switched off. Theinvention can realize the secondary collection of sewage; Can collect initial rainwater, reduce pollutants into the river; Intelligent control system, which can realize automatic rainwater and sewagedistribution; Flood discharge and drainage will not be affected.

Description

technical field [0001] The invention belongs to the technical field of rain and sewage pipe network reconstruction, in particular to an intelligent rain and sewage diversion device for a pipe network, which is mainly used in the field of rain and sewage combined pipe network reconstruction. Background technique [0002] At present, most of the old urban areas in our country adopt the confluence system, and the sewage is directly discharged into the river, resulting in black and smelly water. The diversion transformation of rainwater and sewage pipe network has become an important means of river source control and sewage interception. However, the traditional rain and sewage diversion renovation project has a large workload and a long construction period, which brings inconvenience to residents' life and transportation. In particular, the pipe network in the old urban area is outdated and complicated, and the renovation costs a lot. Practice has proved that implementing suc...

Problems solved by technology

However, the traditional rain and sewage diversion renovation project has a large workload and a long construction period, which brings inconvenience to residents' life and transportation.

In particular, the pipe network in the old urban area is outdated and complex, and the renovation costs a lot

Practice has proved that the implementation of such a project in densely populated urban areas and commercial blocks requires a large amount of engineering and a long construction period, which will bring great inconvenience to residents' lives and traffic

[0003] In addition, if the rain and sewage are simply diverted, and the treatment of the initial rainwater is abandoned, and it is directly discharged into the water body, the highly polluted initial rainwater will become an important source of water pollution.
