[0003] Biological filler is a technology that uses the microorganisms on the specific surface area of the carrier filler to treat the organic matter and pathogenic microorganisms in the pollution source. The pollution source is first absorbed by the filler, and then oxidized and decomposed by the microorganisms attached to the filler. Since the microorganisms are attached to the carrier filler, when the carrier When the filler is saturated with adsorption, it is difficult to provide a suitable living environment for it, so it will gradually lose its ability to treat sewage with the extension of the use time, which requires timely replacement. The reason for this is, on the one hand, the unreasonable design of the filler. , on the other hand, there is no graded treatment of sewage, and one-time treatment cannot make full use of biological fillers

Abstract
The invention provides biological packing for domestic sewage treatment and a preparation method of the biological packing and relates to the technical field of biological packing. The biological packing is characterized by being formed by sequentially connecting first-level packing, second-level packing and third-level packing; sewage sequentially passes through the first-level packing, the second-level packing and the third-level packing; the first-level packing is elastic packing, the second-level packing is bagged packing, the third-level packing is biological packing, the sewage is treated through the three levels of packing gradually, and the elastic packing is a high polymer material and has certain flexibility and rigidity, good resilience and long service life. The bagged packing preliminarily adsorbs organic matter in the sewage through high adsorption capacity of wood charcoal and bamboo charcoal, removes large impurities and reduces loads of the next level of biological packing for treating the sewage, the kinds of microorganisms allowed by the biological packing to grow are rich, a large specific area is provided for inhabitation and growth of the microorganisms, and nutritional ingredients are reasonable.
Description
technical field [0001] The invention relates to the technical field of biological fillers, in particular to a biological filler for domestic sewage treatment and a preparation method thereof. Background technique [0002] The urban sewage pipe network is mainly divided into domestic sewage pipe network, industrial waste water pipe network and natural precipitation pipe network. Due to the large differences in the impurities contained in the water bodies of the three, they must be treated separately. Some water sources are discharged into the sewage pipe network. Pretreatment should also be carried out separately so that the indicators in the water body meet the requirements of the national regulations. Domestic sewage refers to the water used in people's daily life, mainly including water supply equipment without towers from residences, public places, institutions, schools, hospitals, shops and other public buildings and factories, such as toilets, bathrooms, spot washing ro...
