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.

Abstract

The invention provides an efficient filler for sewage treatment. The efficient filler is prepared from the following components including activated carbon, polyether polyol, muck, a silicone surfactant, diatomite, anaerobic digestion bacteria, microorganism bacterium powder and distilled water. A preparation scheme of the efficient filler comprises the following steps: weighing the polyether polyol, the muck, the silicone surfactant and the diatomite according to a ratio, mixing with water, stirring with a low speed by virtue of a stirrer, and slowly adding the activated carbon after weighing in a mixed liquid; and increasing the stirring speed until the mixed liquid and the activated carbon are fully mixed, and adding the anaerobic digestion bacteria and the microorganism bacterium powder after weighing.

Description

technical field [0001] The invention relates to sewage treatment, in particular to a high-efficiency filler for sewage treatment, which belongs to the field of environmental engineering. Background technique [0002] In the past 200 years, urban sewage treatment has developed from the original natural treatment and simple primary treatment to the use of various advanced technologies, advanced treatment of sewage, and recycling. Among them, the biological contact oxidation method is widely used in sewage treatment, and the core technology of the production contact oxidation method lies in the carrier-filler of the biofilm. The fillers commonly used in the existing sewage treatment include honeycomb fillers, soft fillers, semi-soft fillers, three-dimensional fillers, porous rotating suspension fillers, and spiral mesh fillers. Easy to block, poor biofilm adhesion, poor ventilation and water-passing performance. [0003] At present, the number of urban sewage treatment plants...
