Embodiment 1
[0024] 1) After adjusting the pH value of the alkaline industrial waste liquid to be treated to 8, add a flocculant for preliminary sedimentation treatment of organic matter; the flocculant is polyaluminum chloride and dimethyl diallyl ammonium chloride, both The weight ratio is about 2:1, and its addition amount is 0.08g relative to 1L of the waste liquid; the primary sedimentation treatment is carried out under the condition of stirring at a temperature of 40°C;
[0025] 2) The waste liquid after the preliminary sedimentation treatment is left to stand and cooled to below 20° C., and then filtered through a filter with a mesh diameter of 50 μm to obtain a filtrate.
[0026] 3) adopting the acidic solution containing 45% sulfuric acid and 10% ferrous sulfate to continue to adjust the pH value of the filtrate obtained in step 2) to 1.5, adding activated carbon and polyaluminum chloride successively to carry out secondary sedimentation treatment of organic matter; The activated...
Embodiment 7
[0031] The particle size of activated carbon in step 3) in Example 7 was 150 μm, and activated carbon was not used in step 3) in Example 8.
Embodiment 9
[0032] In Example 9, the polyaluminum chloride in step 3) was replaced with dimethyl diallyl ammonium chloride.
