Problems solved by technology

However, due to the loose structure and low strength of humus fillers in the prior art, they are easy to be lost and worn; the content of organic carbon source is low and it is difficult to meet the requirements of denitrification for carbon source, resulting in the inhibition of biological denitrification process; it cannot effectively solve the problem of phosphorus wear Permeation problem, affecting the treatment efficiency of biofilter

Abstract

The invention provides sewage treatment filler and a preparation method thereof. The sewage treatment filler comprises humus, biodegradable plastic and waste particles fired by red soil, wherein the mass percent of the humus is not smaller than 60%. The filler has the advantages that the problem of insufficient carbon sources in the denitrification process can be effectively relieved, and the total nitrogen removal rate is increased; a phosphorus fixation component is provided, the problem of phosphorus penetration can be effectively solved, meanwhile, the structure strength is greatly improved, and the loss and abrasion are not easy; sources of the filler are all from solid waste, waste is treated by using the waste, reutilization of resources is realized, and the filler is beneficial toenvironment protection.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a sewage treatment filler and a preparation method. Background technique [0002] With the increasingly prominent problems of water resources, the treatment of domestic sewage in rural areas has received widespread attention. [0003] In recent years, the treatment of rural domestic sewage by humus-filled biofilters has been widely promoted and applied. Humus-filled biofilters can not only effectively remove suspended solids and organic matter in sewage, but also realize nitrification, denitrification, phosphorus removal and harmful substance removal. However, due to the loose structure and low strength of humus fillers in the prior art, they are easy to be lost and worn; the content of organic carbon source is low and it is difficult to meet the requirements of denitrification for carbon source, resulting in the inhibition of biological denitrification process; it cannot effecti...
