Abstract
The invention provides a small-size anion dye wastewater treatment device. The small-size anion dye wastewater treatment device is composed of two iron-carbon micro-electrolysis reaction tanks, a pH adjusting device and a coagulating sedimentation tank. Wastewater firstly enters the two reaction tanks and discharged water enters the coagulating sedimentation tank so as to reduce the chrominance and the SS of the wastewater. Each reaction tank is internally provided with a reaction liner; an iron-carbon plate is fixedly arranged on each reaction liner; an upper flange cover of each reaction tank is opened and each reaction liner is taken out to replace the iron-carbon plate so as to reduce the problems that fillers are caked and are easy to block and the like. The pH adjusting device is arranged on the upper part of the coagulating sedimentation tank and the pH value of the water in the coagulating sedimentation tank is adjusted; water enters the coagulating sedimentation tank through an upper connection pipe; water distribution holes are formed in the lower part of a water distribution region of the sedimentation tank; five layers of the water distribution holes are formed so that the water can be uniformly distributed and the impact on floc is reduced. Then the wastewater upwards flows through a water output weir to enter a water collection groove and is collected into a water discharging pipe to be discharged out of a tank body. Mud discharging pipes are arranged on the lower parts of the three reaction tanks so as to discharge sediment sludge in time.
