Abstract

The invention provides a wastewater treating technology. The technology specifically comprises the following steps: centrifugally separating; filtering through a ceramic film; processing through anaerobic organism; chemically depositing; and detecting wastewater. The wastewater treating technology has the advantages that a centrifugal separating machine and a cyclone hydraulic separator are combined to effectively remove solid impurities in the waste liquid, so that the foundation is prepared for following wastewater treatment, and the following wastewater treatment efficiency is improved; a ceramic film pipe is adopted, and micropores are distributed in the wall of the ceramic film pipe; wastewater flows in the film pipe or the outer side of the film under the effect of pressure; small molecule materials (or liquid) flow through the film; big molecule materials (or solid particles and liquid droplets) are intercepted by the film, and thus the purposes of solid-liquid separating, concentrating and purifying are achieved; and small particle impurities in the wastewater can be effectively removed; additionally, the ceramic film pipe is spirally raised, so that the contact time of thewastewater and the ceramic film pipe is increased; and moreover, the filtering capacity of the ceramic film pipe can be further improved under the effect of gravity.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a wastewater treatment process. Background technique [0002] The wastewater discharged by people in daily life activities is mainly polluted by domestic waste and human excrement. The quantity, composition and concentration of pollutants are related to people's living habits and water consumption. Domestic wastewater generally does not contain toxic substances, but it has conditions suitable for microbial reproduction, contains a large number of bacteria and pathogens, and is harmful to a certain extent from a hygienic point of view. Wastewater treatment is the use of physical, chemical and biological methods to treat wastewater, purify wastewater, reduce pollution, and achieve wastewater recovery and reuse, making full use of water resources. Contents of the invention [0003] In order to solve the above problems, the invention discloses a wastewater treatment p...
