Abstract

The invention discloses a zero-energy-consumption sewage treatment system, and belongs to the field of sewage treatment. The system comprises a matrix layer for treating sewage, and the matrix layer comprises a matrix adsorption layer, a matrix percolation layer and a matrix water collection layer which are sequentially arranged. According to the sewage treatment system, after adsorption and filtration, water flowing out of the water collection layer meets the environmental requirement, and the treatment effect on initial rainwater runoff pollutants and micro-polluted water is particularly remarkable. The incompressibility of water is fully utilized in the whole treatment process section, potential energy of raw water is converted into kinetic energy for sewage treatment, and therefore zero-energy-consumption operation of sewage treatment is achieved. By adjusting the matrix layer, the treatment of biochemical sewage and non-biochemical sewage can be simultaneously met. The applicationrange of the sewage treatment process is further expanded.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a zero-energy sewage treatment system. Background technique [0002] According to the nature of raw water, sewage treatment can be divided into two categories: biodegradable and non-biodegradable. The main indicator is the B / C ratio, that is, if it is above 0.3, it can be considered as biological treatment, if it is lower than 0.2, it is basically unnecessary to consider biochemical treatment, and how to increase B / C between 0.2 and 0.3——hydrolysis and acidification , advanced oxidation, supplementary carbon source, etc. After the sewage treatment facility is put into operation, its process will not be changed. However, the diversity of the influent raw water of sewage treatment facilities causes large fluctuations in the biochemical properties of the influent water, which in turn causes the contradiction between the biochemical properties of the influent raw water quality and t...
