Abstract
The invention discloses an urban sewage treatment composite material as well as a preparation method and application thereof. The urban sewage treatment composite material is prepared from rice hull, diatomite, polyaluminum chloride and ferment bacteria according to certain weight percentages. The preparation method comprises the following steps: A, uniformly mixing the rice hull and ferment bacteria, and naturally stacking and fermenting for two weeks to obtain a mixed raw material, wherein the fermentation temperature is 65-70 DEG C; B, when in use, uniformly mixing according to a condition that the weight ratio of the mixed raw material to water to brown sugar is equal to 1:0.3:0.01, fermenting for 110-130 minutes for later use, and ensuring that the water temperature of treated sewage is less than 10 DEG C; and C, uniformly mixing the mixed raw material which is fermented for later use with diatomite and polyaluminum chloride according to weight percentages to obtain the composite material. The invention also relates to an application of the composite material in urban sewage treatment. By virtue of the synergistic effects of adsorption, flocculation and biological transformation, the problems that an existing urban sewage treatment system cannot be used for effectively removing some hardly-degradable organic matters and soluble pollutants such as phosphorus and nitrogen can be solved, and thus a condition that effluent can reach the first grade A standard which is superior to the national urban and town sewage discharge standard can be ensured.
