Abstract
The present invention provides a kind of city sewage deep treatment method, sewage-mud is handled by using novel sewage-treating agent, arrange in pairs or groups again activated carbon adsorption processing, filtration treatment, Microbial denitrogenation processing, ultraviolet-sterilization processing, reverse osmosis treatment and distillation processing etc. treatment process, directly sewage-mud is handled as mud cake, fresh water and crystal salt, and the sludge-based activated carbon with excellent absorption property has been made in resulting mud cake；The present invention handles resulting fresh water water quality and has had reached the standard recycled, can direct recycling and reusing, resulting crystal salt can send processing outside.Sewage-mud processing is carried out using sewage water treatment method of the invention, return water rate is improved, realizes the zero-emission of sewage, realize the resource utilization of sewage and sludge, meet the requirement of sustainable development.
Description
Technical field
The present invention relates to water-treatment technology fields, and in particular to a kind of city sewage deep treatment method.
Background technique
Municipal sewage treatment be the municipal sewage that will be discharged in city and factory discharge sewage focus on, also
It is to say that municipal sewage includes sanitary sewage and trade effluent.These sewage due to long-time accumulate, inside containing a large amount of mud,
The harmful substances such as bacterium, heavy metal ion, inorganic compound and organic compound, if being directly discharged to water body without processing
Among, heavy pressure can be brought to water environment, it will the drinking-water health of serious people makes limited water resource by serious
It threatens, or even threatens the survival and development environment of people.Existing sewage treatment method is mostly based on qualified discharge, seldom meeting
In view of waste resource recovery utilizes, although this mode also can be realized the processing of sewage, it be easy to cause the very big wave of resource
Take, and does not meet requirement of the modern society for sustainable development.
