Problems solved by technology

However, this magnetic separation temporary pollution control measure can only remove part of the insoluble pollutants, and the removal rate of ammonia nitrogen and total phosphorus is extremely low. The water quality after magnetic separation treatment is still of inferior water quality. It is easy to produce a large amount of chemical sludge, which will cause secondary pollution to the environment

Embodiment

[0020] An embodiment of the present invention provides a method for preparing an aggregate purification carrier, comprising:

[0021] The aggregate is soaked in the first composite bacterial solution to obtain the aggregate attached with the first composite bacterial solution. The first composite bacterial agent includes: COD degrading bacteria and ammonia nitrogen degrading bacteria; the OD of the first composite bacterial solution 600 is 3.6.

[0022] After 80% of the water in the first composite bacterial solution on the surface of the aggregate evaporates, spray an adhesive on the surface of the aggregate to which the composite bacterial solution is attached, and the temperature of the adhesive is 35-38°C;

[0023] Spraying the second composite bacteria solution on the surface of the adhesive to obtain the aggregate purification carrier. The second composite bacterial agent includes: COD degrading bacteria and ammonia nitrogen degrading bacteria; 50mL of the second compos...

Abstract

The invention provides a preparation method of an aggregate purification carrier, aggregate is soaked in a first compound bacteria solution to obtain the aggregate attached with the first compound bacteria solution, and a compound bacteria agent comprises COD degrading bacteria and ammonia nitrogen degrading bacteria; an adhesive is sprayed to the surface of the aggregate attached with the first composite bacteria liquid, and the temperature of the adhesive is 35-38 DEG C; and spraying a second compound bacteria solution on the surface of the adhesive to obtain the aggregate purification carrier. The aggregate, the adhesive and the compound bacteria liquid used in the method do not pollute the environment, so that the method can purify the polluted water body in an environment-friendly and efficient manner.

Description

technical field [0001] The invention relates to the field of biological water purification, more specifically, to a preparation method of an aggregate purification carrier. Background technique [0002] Urban black and smelly water is a water environment problem that people strongly report, which not only damages the urban living environment, but also seriously affects the image of the city. In recent years, the voice of "Let the mayor swim in the river" reflects the strong desire of the people to solve and control the black and smelly water bodies in the city. [0003] At present, the relatively advanced treatment measures for black and odorous water bodies are temporary pollution control measures of magnetic separation. The temporary pollution control measures of magnetic separation use the magnetism of impurity particles in wastewater to separate them. For non-magnetic or weakly magnetic particles in water, magnetic inoculation technology can be used. make them magnetic....
