Embodiment 1
[0027] A sewage treatment method for biologically active phosphorus and nitrogen, comprising the steps of:
[0028] S1. Preparation of biologically active phosphorus: react a mixture of ethanol, n-pentyl alcohol, and n-dodecyl alcohol with phosphate ions to form organic phosphate; the mass ratio of the ethyl phosphate is 10%, and the mass ratio of the amyl phosphate The mass proportion is 10%, and the mass proportion of dodecyl phosphate is 80%;
[0029] S2. Preparation of biologically active nitrogen: mixing nitro nitrogen and amino nitrogen at a mass percentage of 23% and 77% respectively;
[0030] S3. Mix the biologically active phosphorus obtained in step S1 and the biologically active nitrogen obtained in step S2 into the sewage at a mass ratio of 1:3, then add surfactants and biopromoters in sequence, and aerate at 30°C for 12 hours to obtain treated sewage; the addition amount of each component of the bio-accelerator is: laccase 10 mg·L -1 , trace elements 2 mg·L -1 ...
Embodiment 2
[0032] A sewage treatment method for biologically active phosphorus and nitrogen, comprising the steps of:
[0033] S1. Preparation of biologically active phosphorus: reacting a mixture of n-propanol, cyclohexanol, benzyl alcohol, menthol, and n-tetradecyl alcohol with phosphate ions to form an organophosphate; the carbon atoms in the organophosphate are 2~ 4 accounted for 20%, two phosphate esters with carbon atoms of 5-9 (ratio 1:1) accounted for 40%, and two phosphate esters with carbon atoms 10-15 (ratio 1:1) Accounting for 40%;
[0034] S2. Preparation of biologically active nitrogen: mixing nitro nitrogen and amino nitrogen at a mass percentage of 68% and 32% respectively;
[0035] S3. Mix the biologically active phosphorus obtained in step S1 and the biologically active nitrogen obtained in step S2 into the sewage at a mass ratio of 1:8, then add surfactants and biopromoters in sequence, and aerate at 30°C for 12 hours to obtain treated sewage; the addition amount of ...
Embodiment 3
[0037] A sewage treatment method for biologically active phosphorus and nitrogen, comprising the steps of:
[0038]S1. Preparation of biologically active phosphorus: react a mixture of ethanol, 2-butanol, n-heptanol, and n-undecyl alcohol with phosphate ions to form an organic phosphate; two types of organic phosphates with 2 to 4 carbon atoms Phosphate (ratio 1:1) accounted for 20%, those with carbon atoms 5-9 accounted for 20%, and those with carbon atoms 10-15 accounted for 60%
[0039] S2. Preparation of biologically active nitrogen: mixing nitro nitrogen and amino nitrogen at a mass percentage of 45% and 55% respectively;
[0040] S3. Mix the biologically active phosphorus obtained in step S1 and the biologically active nitrogen obtained in step S2 into the sewage at a mass ratio of 1:5, then add surfactants and bio-growth promoters in turn, and aerate at 30°C for 12 hours to obtain treated sewage; the addition amount of each component of the bio-accelerator is: laccase ...
