Description

Drainage system with regulation facility and integrated treatment facility and drainage control method
Technical Field
The invention belongs to the technical field of drainage, and particularly relates to a drainage system with a regulation facility and an integrated treatment facility and a drainage control method.
Background
At present, drainage systems of cities and building groups mainly comprise a diversion system, a confluence system and a mixed flow system, and the main purpose of the drainage systems is to collect, convey and treat water bodies. For example, a system for treating all waste water in one way is called a combined system. It has only one drainage system, called confluence system, and its drainage pipeline is called confluence pipeline. The system for treating wastewater with different properties in different ways is called split system, and generally has two drainage systems. One, which may be referred to as a rainwater system, is used to collect rainwater and low-pollution industrial wastewater that is directly discharged from a water body without treatment, and the pipeline is called a rainwater pipeline. Another type of system may be called a sewage system, in which domestic sewage is collected and industrial waste water which needs to be treated before it is discharged, and a pipeline thereof is called a sewage pipeline. The mixed flow system is a system between the split flow system and the combined flow system, and is mainly caused by that part of pipelines are connected in a staggered manner, mixed manner and the like in the split flow system area, so that wastewater with different properties appears in part of pipelines, namely, a rainwater pipeline or a sewage pipeline is actually changed into a combined flow pipeline. The wastewater in municipal sewage pipelines and converging pipelines is often referred to collectively as municipal wastewater.
With the advent of modern house sanitary equipment and high-rise buildings, the population is dense, and the feces are conveyed by water flow, so that the strength of urban sewage is greatly increased; in addition, the industrial wastewater is greatly increased, and intolerable pollution is caused in rivers and lakes near the city. And then, adding a sewage treatment plant, connecting the sewage treatment plant with each water outlet by using a pipeline, and collecting and treating the wastewater in each drainage main pipe by using the sewage treatment plant to form a closure type converging system. The pipeline which is connected with the water outlet and intercepts wastewater to the sewage treatment plant is called an intercepting pipeline or a sewage intercepting pipeline.
The amount of wastewater suddenly increases during rainfall, and if all the wastewater is trapped, the interception pipeline and the sewage treatment plant are inevitably required to be large in scale, and engineering cost is excessively increased. The manhole at the intersection of the drain main and the cutoff pipe is typically replaced with a diverter well. The structure of the diversion well can have different designs, but the current design is not perfect, and no improvement is made for different sewage and rain water quantities. In dry seasons, only sewage is contained in the pipe, so that the sewage can be caught by the diversion well and flows to the sewage pipe; during rainy season, part of rainwater and sewage are caught and flow into the sewage pipe, and the rest rainwater overflows through the well weir and flows to the downstream. Most of the current control methods for the flow direction of rainwater and sewage adopt water level or rainfall to control, but the current water level control method or rainfall control method is not good for the diversion control of the rainwater and the sewage, so that the meaning of a diversion well is lost.
