Description

Method for rapidly treating sewage
Technical Field
The invention belongs to the field of sewage treatment methods, and particularly relates to a method for quickly treating sewage.
Background
Along with the increase of urban population in China, domestic water consumption in cities is more and more, urban domestic sewage mainly comprises kitchen washing, toilet flushing, bathing, laundry water and the like, the sewage contains a lot of solid substances, organic nitrogen and ammonia nitrogen, a large amount of solid substances, organic nitrogen and ammonia nitrogen contained in the sewage become main pollution sources of urban water in China, and the urban sewage is discharged into rivers and lakes without being purified to pollute natural water bodies and surrounding environment; a large amount of sewage is directly discharged, so that not only is the ecology damaged, but also the industrial and agricultural production and the health and the safety of human beings are seriously harmed.
When handling domestic sewage, the preliminary edulcoration is filtered to the solid class impurity in the sewage earlier generally, then organic nitrogen and ammonia nitrogen to in the sewage decompose the processing, sewage after the processing can discharge in the middle of the nature, but when filtering the solid impurity in the sewage, adopt filtering material to carry out mechanical filtration to the impurity in the sewage more, filterable in-process, filtration pore in the filtering material can be by quick shutoff, lead to filtering material to need carry out the replacement of high frequency, the in-process of replacement need be to be suspended the filtration of sewage, the filter speed that leads to sewage descends, need consume a large amount of filtering material and filter sewage when filtering simultaneously, lead to the filtration cost height of sewage, and then the filtration efficiency who leads to sewage is with low costs high.
