detailed description

Below in conjunction with accompanying drawing and specific embodiment the utility model is further described.

As shown in Figure 1, a construction site sewage treatment and sewage zero discharge system includes a funnel 1 for filtering suspended matter in sewage, an oil-water separation chamber 2, a filter screen 3 is arranged on the funnel, and the oil-water separation chamber The bottom is provided with a water inlet baffle 4, a liquid level maintaining plate 5 lower than the water inlet baffle, an oil baffle 6 between the water inlet baffle and the liquid level maintaining plate, the water inlet baffle and the liquid surface There is a space above the retaining plate, there is a space below the oil baffle, an oil outlet 7 is provided above the oil baffle, and a water outlet 8 is provided below the liquid level maintaining plate. The funnel is connected to the end of the water inlet partition, and the filter screen is located in the middle and lower part of the funnel, forming a hollow structure, enhancing the filtering performance and preventing the oily sewage from forming a vortex.

In this embodiment, the water inlet partition is used to buffer the oily sewage inlet velocity, and to make the oily sewage flow upward, and to make the oil float up as much as possible under the action of buoyancy; the liquid level maintenance plate is used to ensure that there are The existence of liquid ensures that under the action of buoyancy, the oil cannot flow down and pass through the oil baffle, thus realizing the oil baffle function of the oil baffle.
