The reciprocating pump 5 moves to suck the cleaning water into the pump body and to pump the water into the primary treatment tank during compression. When the oil drain valve 1 is drained, the oil drain valve 1 is closed. This process is an exhaust process.
Primary treatment: the sewage is connected with the water inlet pipe 4, the motor is started, and the motor drives the reciprocating pump 5 to move. The reciprocating pump 5 pumps sewage into the lower part of the primary treatment tank 2, the sewage moves upwards and is blocked by the water baffle device 3, and impurities in the water, especially oils, can be gradually collected from small particles and become large particles. When moving to the agitating holes 3-6, a part of the water flow moves upward from the agitating holes 3-6, and the oil particles in the water are accelerated to become larger. When the sewage moves to the upper part of the primary treatment tank 2, most of the oil moves upwards and is accumulated on the upper part of the primary treatment tank 2. The oil discharge valve 1 at the upper part of the primary treatment tank 2 is opened at fixed time to discharge oil. The solid impurities in the water are gradually deposited in the upward movement process of the water flow, move downwards along the inclined surface and move downwards from the sewage draining grooves 3-4.
Secondary treatment: after primary treatment, the sewage moves into a secondary treatment box 10 from a primary water outlet 2-4. The motor rotates to drive the rotating shaft 9-7 to rotate, the rotating shaft drives the upper stirring fork 9-1 to rotate, and oil drops in the sewage are further gathered and move upwards under the stirring of the stirring fork 9-1. And opening an oil discharge valve 1 at the upper part of the secondary treatment tank 10 at fixed time to discharge dirty oil.
And (3) tertiary treatment: the sewage moves to the tertiary treatment tank 8 under the action of the pressure of the reciprocating pump 5. Through the secondary water outlet holes 8-2 and first to the lower filter 7, solid impurities and dirty oil will remain inside the filter 7 through the filter 7. The sewage moves from the inside to the outside of the filter 7. The sewage moves from the outside to the inside of the upper strainer 7 and is discharged through the facility drain port 8-5.
It is to be understood that the above description is not intended to limit the present invention, and the present invention is not limited to the above examples, and that various changes, modifications, additions and substitutions which are within the spirit and scope of the present invention and which may be made by those skilled in the art are also within the scope of the present invention.
