when the liquid level of the oily sewage reaches 20 percent or the oil level of the waste mineral reaches 90 percent, the control terminal controls the first filtering device and the wastewater pretreatment device to automatically stop filtering treatment and oil skimming treatment;

when the liquid level of the oily sewage is below 70 percent or the liquid level of the domestic sewage is higher than 50 percent, the control terminal controls not to start the first filtering device and the wastewater pretreatment device and does not perform filtering treatment and oil skimming treatment;

and when the liquid level of the oily sewage is more than 70% and the liquid level of the domestic sewage is less than 50%, the control terminal controls and starts the first filtering device and the wastewater pretreatment device to carry out filtering treatment and oil skimming treatment until the liquid level of the domestic sewage is less than or equal to 70%, and the filtering treatment and the oil skimming treatment are stopped.

The water quality oil content detector monitors the oil content in the discharged water in real time, and the water reaching the standard flows back to the domestic sewage storage tankThe substandard water flows back to the oil-containing sewage storage tank, the separated sump oil flows back to the waste engine oil storage tank, and the processing capacity of the waste water pretreatment device meets 2m ³ And h, the content of petroleum hydrocarbon substances in the water reaching the standard after separation is less than or equal to 15mg/L.

The wastewater pretreatment device monitors that water which does not reach the standard is firstly detected, the wastewater enters the oil adsorption device for secondary separation, the oil content detector automatically detects whether the water quality after the secondary separation reaches the standard, if the content of petroleum hydrocarbon substances is more than 15mg/L, the water flows back to the oil-containing wastewater storage tank, and if the content of the petroleum hydrocarbon substances is less than or equal to 15mg/L, the water flows back to the domestic wastewater storage tank.

The oil adsorption device can be used for secondary separation and can also be regarded as an emergency measure, so that a large amount of oil still exists in the sewage after the oil skimming of the wastewater pretreatment device is avoided, and the oil flows back to the oil-containing sewage storage tank again, so that the volume release of the oil-containing sewage storage tank is not facilitated. Through emergency measures, the oily sewage after oil skimming can be separated again, the amount of the oily sewage is greatly reduced, the domestic sewage is greatly separated, and the volume of the oily sewage storage tank is released.

Indicating that the pipeline is blocked or the filtering device is blocked by foreign matters, and the filter element needs to be cleaned or replaced;

wherein α is a threshold value of pipeline fluid stability, and generally α =0.6.

In the practical application process, the pressure gauge and the flowmeter are often not arranged on the same pipeline as shown in the drawing, the pipeline arrangement is three-dimensional, and the pressure gauge and the flowmeter are arranged on the same pipeline but are not necessarily arranged on the same pipeline position, so that the data sample needs to acquire the flow velocity of two straight pipe positions, and the sample set matrix is manufactured by the straight pipe flow velocity and the local flow velocity through conversion. The pressure gauge is used for collecting data of two points to calculate pressure difference and monitoring flow velocity of the straight pipe. The flow meter collects the real-time local flow rate at one point.

Meanwhile, at the same time, a flow velocity sample set matrix is manufactured by adopting the change of the flow velocity and the local flow velocity of the straight pipe, the pressure drop and the local pressure drop of the straight pipe are obtained by calculation, so that a pressure drop sample set matrix corresponding to the flow velocity sample set matrix is obtained, the correlation coefficient between the flow velocity and the pressure drop is calculated, whether warehousing operation is normal is judged, whether the pipeline is blocked or whether a filtering device has foreign matters or not is judged, whether the pipeline needs to be cleaned or whether a filter element needs to be replaced or not is judged, corresponding treatment is timely carried out on the foreign matters in the blocked or filtering device, the warehousing operation is more smooth, and the subsequent treatment work after warehousing is also favorably improved.
