Embodiment 1
[0063] A composite material for urban sewage treatment, which is made of the following raw materials in weight percentage:
[0064] Raw material % by weight
[0065] Rice husk 65%
[0066] Diatomaceous earth 20%
[0067] Polyaluminum Chloride 8.5%
[0069] A kind of preparation method of urban sewage treatment composite material, its steps are:
[0070] A. Mix rice husks and enzyme bacteria evenly, and naturally pile up and ferment for two weeks (14 days) to obtain mixed raw materials; the fermentation temperature range is 65 or 67 or 69 or 70°C; the enzyme bacteria include Bacillus subtilis, yeast Bacteria and actinomycetes; the effective viable count of Bacillus subtilis is 2 billion / g, the effective count of yeast is 3.5 million / g, and the effective count of actinomycetes is 3 million / g.
[0071] B. When using, mix raw materials: water: brown sugar = 1:0.3:0.01 by weight ratio, and ferment for 110 or 115 or 119 or 123 or 125 or 128 o...
Embodiment 10
[0079] An application of urban sewage treatment composite material in urban sewage treatment, the steps are:
[0080] (1) When using, mix according to the weight ratio of mixed raw materials: water: brown sugar = 1:0.3:0.01, ferment for 2 hours and set aside. If the treated sewage water temperature is lower than 10°C, this step can be omitted.
[0081] (2) The mixed raw material is uniformly mixed with diatomite and polyaluminum chloride according to weight percentage to obtain a composite material.
[0082] (3) Put the composite material into the O section of the urban sewage treatment A / O system and start using it. The amount added is 0.2-0.45Kg per ton of sewage.
[0083] After using the urban sewage treatment composite material of the present invention, the effluent of the urban sewage plant can reach the first-level A standard of the national urban sewage discharge standard. (Based on the methods and standards of GB 18918-2002 "Pollutant Discharge Standards for Urban S...
