Embodiment 1

[0028] 1. Put 55 parts of rough porous foamed PP foamed plastic particles into 45 parts of activation solution, stir for 24 hours at a speed of 80 rpm, and soak for 2 days; The activation solution is immobilized on the surface and inside of the foamed plastic particles;

[0029] 2. Take out the suspended filter material from the activation solution, and let it dry naturally in a ventilated and dark place.

[0030] Wherein, the bioactivator is processed by the following method:

[0031] 1) Mix 8 parts of pig liver with 15 parts of wheat flour and 5 parts of alcohol-fermented yeast, and then add 8 parts of glucose to prepare;

[0032] 2) Ferment at room temperature at 30°C and puff for 20 hours to obtain puffed products;

[0033] 3) Add half of the amount of wheat flour, alcohol-fermenting yeast and glucose in step 1) to the puffed product, that is, 7.5 parts of wheat flour, 2.5 parts of alcohol-fermenting yeast and 4 parts of glucose for repeated fermentation for 48 hours to ...

Embodiment 2

[0039] 1. Put 70 parts of rough porous foamed PP foamed plastic particles into 65 parts of activation solution, stir for 30 hours at a speed of 100 rpm, and soak for 3 days; The activation solution is immobilized on the surface and inside of the foamed plastic particles;

[0040] 2. Take out the suspended filter material from the activation solution, and let it dry naturally in a ventilated and dark place.

[0041] Wherein, the bioactivator is processed by the following method:

[0042] 1) Mix 10 parts of pig pancreas with 20 parts of sorghum flour and 10 parts of baker's yeast, and then add 10 parts of skim milk to prepare;

[0043] 2) ferment the mixture obtained in step 1) at room temperature at 40°C, and puff it for 24 hours to obtain puffed products;

[0044] 3) Add half of the amount of wheat flour, baker's yeast and glucose in step 1) to the puffed product, that is, 10 parts of sorghum flour, 5 parts of baker's yeast and 5 parts of skim milk, and repeat fermentation f...

Embodiment 3

[0051] 1. Put 35 parts of rough porous foamed PP foamed plastic particles into 25 parts of activation solution, stir for 22 hours at a speed of 65 rpm, and soak for 1.5 days; The activation solution is immobilized on the surface and inside of the foamed plastic particles;

[0052] 2. Take out the suspended filter material from the activation solution, and let it dry naturally in a ventilated and dark place.

[0053] Wherein, the bioactivator is processed by the following method:

[0054] 1) Mix 3 parts of pig's pancreas with 5 parts of flour mixture and 5 parts of baker's yeast, and then add 3 parts of skim milk; the flour mixture is made by mixing 3 parts of wheat flour and 2 parts of sorghum flour.

[0055] 2) ferment the mixture obtained in step 1) at room temperature at 22°C, and puff it for 18 hours to obtain puffed products;

[0056] 3) Add half of the flour mixture, baker's yeast and glucose in step 1) to the puffed product, that is, 2.5 parts of the flour mixture, 2....

Abstract

The invention discloses an in-situ activation modification treatment method for a suspended filter material, which comprises the following steps of: putting 35 to 75 parts of suspended filter material into 25 to 65 parts of activating solution, stirring for 20 to 30 hours at a speed of 60 to 100 rpm, and soaking for 1 to 3 days; and taking the suspended filter material out of the activating solution, and airing. Compared with the conventional system, a wastewater denitrification treatment system with the modified suspended filter material has the advantages that: (1) the wastewater denitrification treatment system performs aeration in the same tank to remove C and N simultaneously, so the operational control process is simple; (2) COD is not needed to be removed before nitrification; (3) an additional carbon source is not needed to be added for denitrification; (4) acid and alkali respectively generated by the nitrification and denitrification can be partially neutralized mutually, and the addition of reagents is reduced; and (5) effluent backflow is not needed, and a secondary sedimentation tank is not arranged, so the occupied area and investment of equipment are reduced.

Description

technical field [0001] The invention relates to a biological denitrification technology in the field of sewage treatment, in particular to an in-situ activation modification treatment method of a suspended filter material. Background technique [0002] Ammonia nitrogen is one of the main pollutants contained in wastewater. At present, the situation of ammonia nitrogen pollution in water bodies is increasing, and denitrification of wastewater has become a severe task. The traditional wastewater denitrification treatment system is to return part of the water treated by the aerobic device to the anaerobic device, so that the nitrogen components in the water rely on nitrifying bacteria to perform aerobic nitrification in the aerobic treatment device, and then return to the former Anaerobic denitrification is carried out in the anaerobic treatment device, so that the nitrogen components are completely degraded in the form of nitrogen gas. In order to return the aerobic nitrifyin...
