Embodiment Construction
[0039] Such as figure 1 Shown, a kind of micro-electrolysis treatment process of chemical waste water is carried out according to the following steps:
[0040] (1) Wastewater pretreatment:
[0041] A. Micro-electrolysis treatment: After the wastewater from each workshop is collected, it is pumped into the iron-carbon pool, the float-type liquid level controller controls the water inlet switch, the electromagnetic flowmeter controls the water inlet, and at the same time, concentrated sulfuric acid is added to adjust the pH value to about 3. Monitoring is carried out through an industrial online PH meter, air is supplied by a Roots blower, aeration is performed through a PPR perforated aeration device, and iron-carbon micro-electrolysis is carried out. The residence time of wastewater in the iron-carbon pool is about 2 hours;
[0042] B. Primary sedimentation: The effluent from the iron-carbon pool is lifted by the pump to the primary sedimentation tank. In the primary sedime...
