Embodiment 1
[0010]
[0011] Preparation scheme: Weigh polyether polyol, humus, silicone surfactant and diatomaceous earth in proportion, add water to mix, stir with a stirrer at low speed, and slowly add the weighed activated carbon to the mixture; increase stirring and mixing Speed, until the mixture and activated carbon are fully mixed, then add the weighed anaerobic digestion bacteria and microbial powder.
[0012] After immobilization, anaerobic denitrification bacteria can perform anaerobic denitrification for a long time under the condition of coexistence with other microorganisms in an anaerobic environment, and will not digest their anaerobic denitrification ability due to the growth competition of other microorganisms.
Embodiment 2
[0014]
[0015] The preparation scheme is the same as above.
[0016] The invention solves the problem that the total nitrogen in the effluent is difficult to reach the standard due to the relatively low carbon-to-nitrogen ratio of the influent after the sewage treatment plants are generally faced with raising the discharge standard.
Embodiment 3
[0018]
[0019] The preparation scheme is the same as above.
[0020] The filler of the invention is suitable for the treatment of various domestic sewage and common process wastewater. The sewage treatment method of the invention is a low-cost and high-efficiency sewage treatment method.
