Description

Drainage system with drainage 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 storage facility and a drainage control method.

Background technique

At present, the drainage systems of cities and buildings mainly include diversion, confluence and mixed flow systems, the main purpose of which is to achieve the collection, transportation and treatment of water bodies. For example, a system that treats all wastewater in one way is called a combined system. It has only one drainage system, called the confluence system, and its drainage pipe is called the confluence pipe. The system for treating different types of wastewater in different ways is called a split system, which generally has two drainage systems. One can be called a rainwater system for collecting rainwater and industrial wastewater with a low degree of pollution and directly discharging water without treatment. The pipeline is called a rainwater pipeline. The other can be called the sewage system, collecting domestic sewage and industrial wastewater that needs to be treated before it is discharged. The pipeline is called sewage pipeline. The mixed flow system is a system between the split flow system and the combined flow system. It is mainly due to the fact that some pipes have different types of waste water, that is, rainwater pipes or sewage, due to the misconnection and mixing of pipes in the area of the split flow system. The pipe actually becomes a merged pipe. The sewage in the city's sewage pipelines and confluence pipelines are often referred to as urban sewage.

With the emergence of modern house sanitation equipment and high-rise buildings, the population is dense, the manure is transported by water, which greatly increases the intensity of urban sewage. In addition, the industrial development, industrial wastewater increases, and the rivers and lakes near the city are intolerable. . Therefore, a sewage treatment plant was added, and each water outlet was connected by a pipe, and the wastewater in each drainage main pipe was collected and treated by a sewage treatment plant to form a intercepting combined flow system. A pipe that connects the water outlet and intercepts the wastewater to the sewage treatment plant is called a intercepting pipe or a sewage intercepting pipe.

When the rainfall increases, the amount of wastewater increases rapidly. If all the wastewater is intercepted, the intercepting pipeline and the sewage treatment plant will inevitably require a large scale and excessively increase the engineering cost. Therefore, the inspection well at the intersection of the drain main and the intercepting pipe is generally replaced with a diverting well. The construction of the split shaft can have different designs, but the current design is not perfect and there is no improvement for different amounts of sewage and rain. During the dry season, there is only sewage in the pipe. The diversion well can intercept the sewage and flow to the sewage pipe. During the rainy season, part of the rainwater and sewage will intercept and flow into the sewage pipe. The rest of the rainwater will overflow through the well and continue to flow downstream. For the flow of rainwater and sewage, most of the current control methods are controlled by water level or rainfall. However, the existing water level control method or rainfall control method does not control the shunting of rainwater and sewage well, thus losing the diversion. The meaning of the existence of the well.

Summary of the invention

In order to solve the deficiencies of the prior art, the present invention provides a drainage system with a storage facility and a drainage control method for intercepting and diverting rainwater and/or combined sewage, through reasonable regulation, The dirty water is intercepted, and the clean water is discharged to the natural water body, which reduces the pollution load discharged to the natural water body and protects the natural water body.

3) The drainage system of the present invention includes a storage and storage facility. During the rain, due to the large rainfall intensity, the initial rainwater that cannot be intercepted to the sewage treatment plant in time is sent to the storage facility for storage, and the later clean rainwater is directly discharged to the storage facility. Natural water bodies can reduce the number of overflows and overflows during rainfall, thus reducing the overflow pollution of rainwater.

4) An online processing facility may be disposed at the third water outlet of the drainage system of the present invention; the online processing facility can effectively solve the dirty water that can be polluted by the natural water body when the fourth water conservancy switch is turned on, and completely The initial rainwater and the mid-late rainwater flow are treated.
