Description

Technical Field

[0002] Direct discharge of oily wastewater will cause great environmental and social harm. Specifically, when oily wastewater is discharged into rivers, lakes or bays, the oil layer covers the water surface, preventing the diffusion of oxygen in the air into the water, reducing the dissolved oxygen in the water, limiting the photosynthesis of algae, and even making the water smelly, destroying the utilization value of water resources, polluting the water body, and affecting the survival of aquatic organisms; when used for agricultural irrigation, it will block the pores of the soil, preventing air from entering, and the soil and microorganisms will not be able to metabolize normally, hindering the growth of crops, and in severe cases, causing crop yield reduction or death. The more important hazard of oily wastewater is that petroleum also contains carcinogenic hydrocarbons, which are enriched by fish and shellfish and endanger human health through the food chain.

The camera 18 is connected to the PLC control cabinet 19 via the third data line 23. The PLC control cabinet 19 is connected to the computer 20. Therefore, the camera 18 takes a real-time image of the wastewater in the graduated glassware 17, analyzes the wastewater image, and obtains the thickness of the oil layer and the thickness of the mud layer sedimentation, thereby adjusting the water inlet flow rate of the fully automatic oil separation regulating unit so that the water inlet flow rate can ensure the best separation effect of the fully automatic oil separation regulating unit. The water inlet flow rate is controlled by controlling the opening height of the water inlet regulating valve 5 to ensure that the water inlet flow rate is between 1-2 mm / s. If there is no obvious oil layer thickness, it indicates that the oil separation effect is good. If there is an obvious oil layer thickness, the height of the water inlet regulating valve 5 needs to be lowered.

[0040] The utility model has the following beneficial effects: good oil-water separation effect and the function of regulating water quality and quantity. No manual oil scooping is required. The oil is collected through the oil collecting pool and the waste oil is lifted to the waste oil barrel through the waste oil lifting pump. It has the characteristics of low investment, simple structure, low energy consumption, high efficiency, automatic control and easy maintenance.

[0041] The above is only a preferred embodiment of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications should also be considered as the protection scope of the present invention.
