To utilize microorganism by the oxygen-enriched ingredient oxygenolysis in sewage；
(5) pH of water after step (4) processing is adjusted to 6-8, after disinfection by chlorine, that is, completes sewage disposal.
In step (1), the adsorbent is ferric hydroxide colloid and alumine hydroxide colloid according to mass ratio 1-2:1-2 is formed
Mixture.
The mass ratio of the adsorbent and the sewage is 1:100-1:500.
The time for carrying out the adsorption treatment is 2-8h.
In step (2), first carries out pH and be adjusted to 6-8.
The additive amount of a concentration of 3-30wt% of the hydrogen peroxide, the hydrogen peroxide account for sewage quality after the adsorption treatment
1%-10%.
In step (2), the additive amount of the sodium pyrosulfate accounts for the 0.05%-0.2% of sewage quality after the adsorption treatment.
The actual conditions of ultraviolet light processing are：Temperature be 20-50 DEG C, mixing speed 200-250r/min
Under conditions of, utilize 300-400nm ultraviolet lights 30-60min.
The mass ratio of the inorganic agent and the sewage is 1:80-1:200.
