as shown in fig. 1, an acidic cleaning water recycling system can be used for treating acidic wastewater containing phosphoric acid and sulfuric acid and having a pH value lower than 2, and comprises a wastewater collection tank 1, a physicochemical treatment tank 2, a sludge concentration tank 3, a filter assembly 4 and an RO reverse osmosis system 5 which are sequentially arranged.
The materialization treatment tank 2 comprises a pH adjusting tank 21, a reaction tank and a flocculation tank 24; in this embodiment, the pH adjusting tank 21 is connected to a sodium hydroxide adding tank and a pH detector; the reaction tanks are provided with two reaction tanks, and further comprise a first tank body 22 and a second tank body 23; the first tank body 22 and the second tank body 23 are both connected with a PAC adding tank; the flocculation tank 24 is connected with a PAM addition tank. Meanwhile, liquid level sensors and stirring mechanisms are arranged in the pH adjusting tank 21, the first tank body 22, the second tank body 23 and the flocculation tank 24; the internal liquid storage capacity is the same, and the rotating speed of the corresponding stirring mechanism is 100rpm. In the physicochemical treatment stage, the primary treatment of the acidic wastewater is realized by adjusting the pH value and flocculating settling.
