As described in the background art, the prior art uses a pipe to guide oily sewage enclosed inside a fire dike into a drainage system or a sewage treatment system, which has a limited treatment capacity, and a large amount of rainwater is accumulated in the fire dike of an oil tank field in rainy season, and the upper limit of the treatment capacity of the drainage system or the sewage treatment system is easily exceeded.
Therefore, the following embodiments provide a distribution system of rain and sewage in a fire dam of an oil tank field, which collects accumulated water by using a water collecting well in the oil tank field, and when equipment, pipelines and valves in the fire dam are damaged or overhauled or dirty oil exists under other conditions, and when the system is cleaned by water flushing, the system sends oily sewage into a drainage system or a sewage treatment system by using a pipeline connected with the water collecting well; when dirty oil does not exist, the water collecting well collects accumulated water and then sends the accumulated water into a rainwater pipeline; when the rainfall is large and no dirty oil is contained in the rain season, the overflow port on the water collecting well is used for guiding the redundant rainwater into a rainwater ditch around the oil tank area; the oily sewage and the rainwater are separated, so that the treatment load of a drainage system or a sewage treatment system is indirectly reduced.
The first embodiment is as follows:
as shown in fig. 1-3, the purpose of this embodiment is to provide a distribution system of rain and sewage in a fire dike of an oil tank field, which includes a water collecting well 3 and a valve well 5 arranged in parallel, the water collecting well 3 is located at the inner side of the fire dike 4 of the oil tank field, the valve well 5 is located at the outer side of the fire dike 5, and a sewage pipe 6 and a rainwater pipe 7 both pass through the valve well 5 and are connected with the water collecting well 3.
The sewage pipe 6 is provided with an oily sewage stop valve, the rainwater pipe 7 is provided with a rainwater stop valve, and the two stop valves are both positioned in the valve well 5.
The bottom height of the valve well 5 is not higher than that of the water collecting well 3, so that the two cut-off valves can be operated conveniently.
As shown in fig. 1, the area of the oil storage tank 1 surrounded by the fire dike 4 is an oil tank area, a water collecting well 3 is arranged at one corner of the oil tank area, and a valve well 5 is arranged at one side of the oil tank area, which is separated from the water collecting well 3 by the fire dike 4.
As shown in figure 2, the well head plane of the water collecting well 3 is flush with the ground of the oil tank area, and the height of the well bottom is not more than the ground elevation of the oil tank area. The water collecting well 3 is a region with the lowest height in the area enclosed by the whole fire dike 4, which is convenient for collecting accumulated water, and a steel grating 32 is arranged at the mouth of the well and can prevent objects with large volume (such as plastic bottles, waste pipelines and the like) from entering the well along with the accumulated water; the steel grating 32 is movable to facilitate replacement after corrosion damage.
When equipment, pipelines and valves in the fire dam are damaged or overhauled or dirty oil exists under other conditions and is cleaned by water flushing, the oil-containing sewage is collected by the water collecting well 3, and the oil-containing sewage cut-off valve is opened, so that the oil-containing sewage in the water collecting well 3 enters a drainage system or a sewage treatment system through the sewage pipe 6;
when no dirty oil exists, the oil-containing sewage stop valve is closed, and the rainwater stop valve is opened, so that accumulated water collected by the water collecting well 3 enters the rainwater pipeline 7.
