A wastewater recycling system for light industry

A wastewater recycling system for light industry comprises a wastewater disposal cistern 16. A power delivering mechanism 51 is arranged in the wastewater disposal cistern, wherein the power delivering mechanism comprises a base 26 connected to a lower end wall of the wastewater disposal cistern. A cylindrical groove 11 with an upward opening is arranged in the base. A power motor 28 is arranged on a lower end wall of the cylindrical groove. Printing and dyeing wastewater can be treated in the cistern by starting the power motor to rotate power shaft 27, thus rotating driven bevel gear (33, Fig. 2). Fan blades (36, Fig. 2) may be driven to rotate to conduct air through grooves 12 and air discharge blocks 29 to aerate the wastewater in the cistern. Transmission shaft 15 is driven to rotate by the power shaft, thus driving transmission bevel gear 23 to rotate. The transmission wheels 17 and water baffles 18 may be driven to rotate through the transmission between the transmission bevel gear and large bevel gears 21 to stir the wastewater and enlarge the contact area between the wastewater and the air.
