Embodiment 1

[0022] A phosphorus-free sewage treatment method is to process sewage through a moving bed biofilm reactor. The filling rate of the biofilm filler in the reactor is 20%, the pH is controlled at 5, the temperature is 20°C, and the treatment time is 72 hours. ; Wherein, the biofilm filler is made of the following components: phenolic resin 48kg, polyphenylene sulfide 42kg, diatomaceous earth 11kg, light calcium carbonate 8kg, fullerene 0.5kg. The biofilm filler is hollow tubular, with axially intersecting reinforcing ribs inside, and the outer surface is serrated. The diameter and height of the hollow tube are equivalent

[0023] The preparation method of the biofilm filler comprises the steps of:

[0024] (1) Dissolve the formulated amount of phenolic resin in absolute ethanol, then add the formulated amount of fullerene, stir to disperse, and fully ball mill; the mass-volume ratio of phenolic resin to absolute ethanol is 1g: 120mL;

Abstract

The invention discloses a phosphorus-free environment-friendly sewage treatment method. According to the sewage treatment method, sewage is treated through a moving-bed biofilm reactor, the filling rate of biofilm filler in the reactor is 20-25%, the pH is controlled to range from 5 to 6, the temperature is controlled to range from 20 DEG C to 30 DEG C, and the treatment time is 72 h; the biofilm filler is prepared from, by weight, 48-55 parts of phenolic resin, 42-51 parts of polyphenylene sulfide, 11-20 parts of kieselguhr, 8-15 parts of light calcium carbonate and 0.5-0.8 part of fullerene. By means of the sewage treatment method, the COD concentration, NH3-N concentration and TP concentration of outlet water all reach the national emission standard, especially, the TP concentration of the outlet water is lower than the limit of detection, and TP can be completely removed; the sewage treatment method is free of phosphorus and environmentally friendly.

Description

technical field [0001] The invention relates to a sewage treatment method, in particular to a phosphorus-free sewage treatment method, and belongs to the technical field of sewage treatment. Background technique [0002] With the increasing scale of industrialization, the discharge of industrial sewage is large, which brings great harm to the environment of cities and towns. For the sewage discharged from the pollution source, if it fails to meet the discharge standard or does not meet the environmental capacity requirements, it should be treated accordingly. At present, sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, and catering. . However, the traditional sewage treatment process cannot meet the needs of modern production, and the treatment time is long and the input cost is high. [0003] Phosphorus content is an important indicator...
