Description
Technical Field
The invention belongs to the technical field of sewage treatment, and particularly relates to a flow regulating and controlling device suitable for the front end of an underground sewage plant.
Background
The development of the sewage treatment plant in China can be simply divided into three stages of sewage treatment plant from the absence to the existence, cover deodorization and start to go to the ground.
Stage one: wastewater treatment plants are in the stage from scratch. In 1920 to 2000 years, sewage treatment plants in China are developed from primary treatment to secondary treatment from the nonexistence to the existence, and sites are generally selected in suburbs far away from cities, so that the odor problem is not concerned for a long time.
And a second stage: and a cover deodorization stage of the sewage treatment plant. In 2000-2010, sewage treatment industry is rapidly developed, urbanization enables a sewage treatment plant located in suburbs in the past to become a central area of a city, and in the process of building, expanding or transforming the sewage treatment plant, tank body covering and deodorization become basic requirements, the environment of a plant area is improved to a certain extent, but the odor problem is not solved fundamentally, the ground landscape environment is not paid enough attention, and the phenomenon of disturbing residents caused by the odor problem of the sewage plant is more and more frequent.
And a third stage: the sewage treatment plant starts the "below the ground" phase. After 2010, with the construction and commissioning of the first full-underground MBR sewage treatment plant in China, namely Guangzhou Jingxi underground water purification plant, underground sewage treatment plants in various regions begin to develop rapidly, the traditional image recognition that odor, noise and full order which people cannot avoid the underground sewage treatment plants are sewage tank bodies is overturned by the underground sewage treatment plants, the sewage treatment plants begin to be integrated into the central area of the city, and the ground garden type environment of the sewage treatment plants thoroughly solves the problem that the traditional sewage treatment plants and the grid of the urban living environment cannot be integrated.
Under the background that urbanization is rapidly promoted, urban land is more and more scarce, and the requirement of people on the environment is more and more high, the underground sewage plant has more and more remarkable advantages in the aspects of land saving and environment friendliness. The underground sewage plant mainly produces and constructs and locates the underground space, each treatment structure and auxiliary building are wholly or partly set up in the space under the ground, the ground of factory is as building (generally factory comprehensive building, office building), parking area, stadium, road, park or afforestation landscape, etc. other uses. The tank body is designed into a commonly-called double-layer capping mode, namely the tank body is capped to meet the deodorization requirement, and the tank surface maintenance space is capped and isolated from the underground to create a good ground environment. Daily field operation and maintenance are mainly performed in underground spaces. The operators can often carry out production activities such as daily inspection, operation, maintenance and the like in the underground space. The typical form of the vertical section is generally divided into three layers: the underground negative two layers (a sewage treatment structure tank layer), the underground negative one layer (a treatment tank surface layer, a production auxiliary building layer and a production operation management space layer) and the ground layer (a ground other use layer).
The buried sewage plant is deeply buried underground, the operation layer is 8m-10m below the ground, and the risk of flooding is large. The main risk sources are: 1. flood outbreak, the water level is higher than the operation layer; 2. a large amount of rainwater enters a sewage pipe network in rainy season, so that the sewage quantity is multiplied, and a buried sewage plant cannot timely absorb sewage; 3. equipment failure in the plant results in outage, and sewage cannot be prevented from entering a sewage plant in time. At present, in order to prevent the underground sewage plant from being flooded, a gate is often installed at a sewage inlet of the underground sewage plant to regulate and control the flow of sewage.
Prior art 1: the flow regulating and controlling technology of the wall-attached type common electric gate comprises the following steps: an electric gate is arranged on an auxiliary wall at an inlet of the underground sewage plant for sewage to enter, and the electric gate is opened and closed by a liquid level control feedback signal to realize flow regulation and flow control of the sewage plant inlet water.
The main disadvantages of prior art 1:
1. the wall-attached common electric gate is longer in time interval from signal receiving to opening and closing, which is about 1-3 minutes. The timeliness of adjusting and controlling the flow of the sewage is poor, and the risk of overflowing the sewage is high.
2. The wall-attached type common electric gate is in a reverse stress mode, the failure rate is high after long-term operation, only one gate protection is provided, and the risk coefficient is high.
3. The common wall-attached electric gate has poor flow regulation effect on sewage and cannot effectively regulate the operating water level.
Prior art 2: the flow regulating and controlling technology of the wall-attached quick-closing gate comprises the following steps: an electric or pneumatic quick-closing gate is arranged on an auxiliary wall at an inlet of the underground sewage plant, and the flow regulation and flow control of sewage are realized by controlling the opening and closing of the feedback quick-closing gate by liquid level. The quick-closing gate has quick response time from signal receiving to opening and closing execution, about 10-30 seconds, and can effectively avoid the risk of sewage overflow.
The main disadvantages of prior art 2:
1. the wall-attached quick-closing gate is in a reverse stress mode, and the failure rate is high after long-term operation.
2. The wall-attached quick-closing gate has poor flow regulation effect on sewage and cannot effectively regulate the operating water level.
3. Only one quick-closing gate protection is provided, and the risk coefficient is relatively high.
