Embodiment Construction
[0034] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, and the implementation scope of the present invention is not limited thereto.
[0035] like figure 1 As shown, the complex heavy metal wastewater emergency rapid treatment method described in this embodiment includes the following steps according to the sequence of procedures:
[0036] (1) Sand filter filtration, sending wastewater containing complex heavy metals into a sand filter for filtration treatment, filtering out large particles of impurities in wastewater, improving the transparency of wastewater, and facilitating subsequent ultraviolet light irradiation;
[0037] ⑵, high-speed pump mixing, high-speed pump will ozone, oxygen (O 3 +O 2 ) and the wastewater from step ⑴ are mixed at high speed to produce mixed bubbles of micro-nano-level ozone and oxygen, thereby increasing the reaction contact area of ozone and oxygen with wa...
