Description
Technical Field
The invention relates to the field of sewage treatment, in particular to a rainwater sewage disposal and diversion system.
Background
The petrochemical device can not avoid the existence of ground pollutants in the production process, and the initial rainwater automatically flows into the rain drainage ditch and flows into the initial rainwater pool when raining, and then is conveyed by the pump pressure to enter the oily sewage pipeline system of the plant. According to the proposal of the design code of the water supply and drainage system of petrochemical enterprises (SH3015-2003), the polluted rainwater at the early stage of rainfall in the area range of the plant device area is calculated according to 15-30 mm of the depth of rainfall, and an early stage rainwater pool is arranged for pumping separation. A major problem with this type of rainshed system is that the initial rain pool volume and sewage pump pumping capacity often do not meet the demand for diversion of the cleaning fluid when a heavy rain event is encountered. Meanwhile, the downstream sewage treatment plant is often in a high-load operation state during rainstorm, and is difficult to receive excessive rainwater again, so that a large amount of oily sewage in the initial rainwater pool is back-mixed and overflows to enter a clean rainwater system.
The common counter measures are that a diversion pond is generally arranged at the collection position of a rain drainage ditch, a double-loop switching valve is adopted, and a rainwater behind 15mm rainfall (or 15 minutes) is switched to a clean rainwater system by means of a manual switch valve, so that the overflow of an initial rainwater pond is avoided. However, this operation has two problems:
1. the 15mm rainfall in the production device area during rainfall is difficult to grasp timely and accurately, and the operability is not strong. If the time requirement of 15 minutes of initial rainwater easily causes the valve switching time to be too early, directly cutting the oily sewage into a clean rainwater system; or the switching time is too late, and the initial rainwater pool still overflows when the liquid level is full, so that back mixing is caused;
2. during the rainstorm, workers need to enter the underground rainwater well to turn on and off the valve, so that the safety risk that the workers slip and fall exists, and the labor intensity is high.

In order to better understand the above technical solution of the present invention, the following further describes the above technical solution of the present invention through specific installation and using methods.
The installation process comprises the following steps:
1) the rainwater sewage-cleaning and diversion system is placed into a rainwater well at the boundary of the existing chemical device, and the opening direction of a rainwater inlet 11 on the water storage tank 1 is consistent with the opening direction of a rainwater drainage ditch and is tightly attached to the well wall. The original procedure of the rainwater well to the initial rainwater pool is kept unchanged, in addition, a clean rain collecting hopper 91 and a clean rain discharging pipeline 92 from a clean rain discharging port to the clean rainwater pool are arranged in the rainwater well, and an emergency stop valve 93 is arranged on the clean rain discharging pipeline 92. The clean rain outlet is opposite to the clean rain collecting hopper 91, so that the clean rain water at the middle and later stages enters the clean rain collecting hopper 91 and then enters the clean rain water pool.
2) The rainwater receiving plate 21 is connected with a rainwater interface hose at the first end of the first pipe body 31, the action conditions of the first cover body 61 and the second cover body 62 are tested by using quantitative water, and the first cover body and the second cover body can be put into use after the normal activity is confirmed.
The working process is as follows:
1) when it is not raining (initial state), the first pipe body 31 is tilted, the second pipe body 32 falls, that is, the initial rain outlet is opened, the normal flow of the rainwater well to the initial rainwater pool is opened, the clean rain outlet is closed, and the flow of the rainwater well to the clean rainwater pool is closed.
When rainfall occurs, the rainwater receiving disc 21 starts to work, rainwater enters the first pipe body 31 through the first conveying pipe 22 and the second conveying pipe 23 at the lower part of the rainwater receiving disc 21, a small amount of rainwater is discharged from the liquid discharge holes 311 at the bottom of the first pipe body 31, the water discharge speed of each liquid discharge hole 311 is not more than 0.5 ml-1.5 ml of liquid drops per second, and the water discharge speed can be controlled through adjusting a needle valve. When the rainfall does not reach 15mm, the first pipe body 31 is not filled with rainwater. The stress conditions at the two ends of the balance pipe adjusting pipe 3 are as follows: the first tube 31 is smaller than the second tube 32, and the balance tube adjusting tube 3 still keeps the tilting state of the first tube 31 and the falling state of the second tube 32.
If the continuous rainfall is less than 15mm, the water stored in the first pipe 31 will be slowly discharged through the 3 liquid discharge holes 311 until the water is emptied, and the balance pipe adjusting pipe 3 keeps the state that the first pipe 31 is tilted and the second pipe 32 falls. The catch basin always keeps the normal flow to the initial catch basin open and the flow to the clean catch basin is closed.
2) When the continuous rainfall of raining exceeds 15mm, the first pipe body 31 begins to be filled with rainwater until the weight of the rainwater collected by the first pipe body 31 exceeds the weight of the balancing weight 7, and then the stress of the first pipe body 31 is larger than that of the second pipe body 32.
The first pipe 31 falls gradually, the second pipe 32 tilts gradually, the stored water in the first pipe 31a enters the second pipe 31b quickly due to the inclination of the balance, and the force arm of the first pipe 31 increases quickly. The second pipe 32 is tilted to open the clean rain outlet, and the first pipe 31 falls to close the first rain outlet. The initial rain outlet is closed, the normal flow of the rainwater well to the initial rainwater pool is closed, the clean rain outlet is opened, and the flow of the rainwater well to the clean rainwater pool is opened.
3) When the rain stops, the rainwater receiving tray 21 no longer collects the rainwater, and the water stored in the first pipe 31 is slowly drained through the drain holes 311. Since the drainage speed of the drain holes 311 is slow, the second pipe 32 still tilts at the beginning, the first pipe 31 still falls, and rainwater entering the rainwater well after the device area converges can still be fully discharged through the clean rainwater system after the rain stops.
4) The first pipe 31 continuously drains water through the drain hole 311, when the stress of the first pipe 31 is smaller than the stress of the second pipe 32, the second pipe 32 falls, the first pipe 31 tilts, water stored in the first pipe 31 moves towards the fulcrum, the force arm of the first pipe 31 is smaller than the force arm of the second pipe 31, the second pipe 32 falls to drive the clean rain outlet to be closed, and the first pipe 31 tilts to drive the first rain outlet to be opened. The normal flow of the rainwater well to the initial rainwater pool is opened, and the flow to the clean rainwater pool is closed. The water stored in the first pipe 31 is discharged through the left drain hole 311, and the automatic rainwater and dirt removing and diversion system restores to the state before raining, that is, the first pipe 31 tilts and the second pipe 32 falls.
Although the present invention has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
