Embodiment approach

[0030]As an embodiment of the present invention, a one-way valve that conducts one-way downwards is provided on the flow hole 19. Through the setting of the one-way valve, the one-way flow of the flow hole 19 can be realized, which not only realizes the forced mixing of the air above the piston 18 to the bottom of the piston 18 and the sewage, but also prevents the sewage from entering the vertical cylinder 15 above the piston 18 Cause pollution problems.

[0031]When in use, the sewage to be treated is introduced into the treatment tank 1 through the sewage inlet pipe 3, and the motor 5 is started; due to the arrangement of the main stirring rod 10 and the second spring 12, the sliding sleeve 11 can overcome the second spring under the action of centrifugal force The elastic force of 12 moves to the outside, so the position of the sliding sleeve 11 is different when the rotation speed of the first rotating shaft 6 is different, so it can stir the sewage back and forth, increase the ef...

Abstract

The invention relates to the technical field of sewage treatment, in particular to a factory sewage treatment tank. The factory sewage treatment tank comprises a treatment tank and a cover plate detachably connected above the treatment tank, a sewage inlet pipe extending to the liquid level in the treatment tank is arranged on one side of the cover plate, a sewage outlet pipe extending to the bottom in the treatment tank is arranged on the other side of the cover plate, a motor is fixedly arranged in the middle of the upper end of the cover plate, the output end of the motor is in transmissionconnection with a first rotating shaft, the first rotating shaft extends into the treatment tank, the first rotating shaft is sleeved with a shaft sleeve capable of sliding up and down, and a plurality of horizontally-arranged main stirring rods are fixedly arranged on the shaft sleeve. By arranging the main stirring rod and the auxiliary stirring rods, sewage can be fully stirred, the flocculation effect is improved, the flocculation efficiency is improved, and therefore the expected water quality requirement is met.

Description

Technical field[0001]The invention relates to the technical field of sewage treatment, in particular to a sewage treatment tank for factories.Background technique[0002]For the current sewage treatment system, it mainly includes three parts: a pretreatment system, a biochemical treatment system, and a muddy water filtration system; the pretreatment system is mainly composed of a grid filter tank and a regulating tank, which are used to filter out large particles of impurities and make sewage The water quality is kept uniform; the biochemical treatment system is mainly composed of anaerobic, anoxic, aerobic and other treatment systems. In the case of large sewage treatment capacity, it is usually composed of anaerobic, anoxic, and aerobic tanks. In the pond, it is necessary to add anaerobic bacteria, aerobic bacteria, etc., to make them react with the nitrogen and sulfur elements in the sewage to remove eutrophic substances; the muddy water filtration system is mainly composed of an a...
