Problems solved by technology
[0002] At present, sewage biological treatment adopts biological contact oxidation method. The traditional sewage biological treatment method has disadvantages such as large investment, high energy consumption, and complicated management in its process and equipment. The biofilm attached to the carrier is mainly used to purify organic wastewater This high-efficiency water treatment process has been widely used in textile printing and dyeing, wool spinning and knitting, beer food, petrochemical, pharmaceutical papermaking, and domestic sewage, and has achieved obvious social effects. The fillers used in this method include rock wool, sand, wood, etc. Brown, soft packing, combined packing and other packings are hanging packing and floating ball, multi-faceted hollow ball, soft packing and other suspended packing. , soaked in sewage for a long time, the bracket is easily corroded, and it is easy to cause the bracket to collapse and cause the packing to be scrapped

Embodiment 1
[0010] Ingredients (%): montmorillonite powder 90-95, foaming agent 3-4, water glass 0.6-0.7, magnesium hydroxide 0.2-0.3;
[0011] Preparation:
[0012] First mix montmorillonite powder and water at a ratio of 3:1, then add foaming agent, water glass, and magnesium hydroxide in turn, stir to dissolve and form fine foam, then add montmorillonite powder, and process it into shape by injection molding , calcining at a temperature of 1000-1100°C for 7-9 hours;
Embodiment 2
[0014] Ingredients (%): water 32, blowing agent 3, water glass 0.6, magnesium hydroxide 0.3, montmorillonite powder 90, its preparation method is the same as embodiment one.
[0015] The invention includes montmorillonite powder, foaming agent, water glass, magnesium hydroxide and other components, wherein magnesium hydroxide and water glass are used as cementing agents to make the filler easy to form, and the function of the foaming agent is to adjust the porosity of the filler and control the filler proportion.

The invention provides sewage biological treatment inorganic filler that requires no fixation and has strong adaptability. Montmorillonite powder, foaming agent, soluble glass, magnesium hydroxide, etc. are adopted as raw material; the soluble glass and the magnesium hydroxide are adopted as cementing agent; the filler can be molded easily; the foaming agent can regulate the gas porosity of the filler and control the specific gravity of the filler; the invention has simple manufacture technique and low cost, and can be stored outside for a long time; as the filler has micro-pore structure and big and coarse surface, thus being suitable for the survival of microorganism; the purifying capacity of the microorganism to domestic sewage is improved substantially; the invention has good sewage treatment effect and convenient use, and can be put into a biochemical reactor directly, without having to be fixed; impurities in the sewage are finally converted into plant cells and animal protein, thereby purifying the sewage to the same standard of tertiary treatment; no secondary pollution is caused; ecological equilibrium is realized through self-regulation; the invention is particularly suitable for the sewage treatment of small towns.
