Embodiment Construction
[0017] A kind of comprehensive waste water advanced treatment method of the present invention, comprises the following steps:
[0018] (1) The mixed wastewater first enters the regulating tank for aeration and stirring, so that the water quality and quantity of the mixed wastewater are uniform;
[0019] (2) pump the waste water in step 1 into the biological treatment system of hydrolytic acidification-anaerobic-aerobic reaction, carry out biochemical treatment;
[0020] First of all, the macromolecular organic matter that is difficult to be biodegraded is decomposed into easily degradable acids and alcohols through the action of hydrolysis and acidification bacteria, the biodegradability of wastewater is improved, and sulfate ions are removed to a certain extent; the wastewater after hydrolysis and acidification enters the HAF pool, The HAF pool is the methanogenic phase of a two-phase composite anaerobic reactor. A large amount of COD removal in the anaerobic process is done...
