Three-dimensional ecological deodorization dephosphorization denitrification method as well as device and application

Abstract

The invention provides a three-dimensional ecological deodorization dephosphorization denitrification method, which is characterized in that in a sewage treatment system, multiple groups of water plants are suspended inside a reaction pond, an isolation purification layer capable of adsorbing the odor and preventing the odor from being scattered outwards is formed through branches and leaves of the water plants when an application system carries out the purification treatment and odor overflows upwards, and root and stem systems of the water plants in the sewage are used as ecological filler to adsorb and degrade the microorganisms and adsorb the odor, so that the deodorization dephosphorization denitrification treatment of waste water can be realized. The invention also provides a deodorization dephosphorization denitrification device designed according to the method and an application in processes such as sequencing batch reactor (SBR), Anoxic-Oxic (A/O), Anaerobic-Anoxic-Oxic (A2/O), AB method, oxidation ditches, membrane biological reactor (MBR), modified university of cape town (MUCT) and the like. The sewage treatment plants of different processes are upgraded and modified, an ecological treatment way with low cost which is domain on a traditional sewage treatment system and assisted by purification organism through the plants is realized, and the pollutants can be maximally biologically degraded.

Description

technical field [0001] The invention relates to the field of wastewater treatment, in particular to a three-dimensional ecological purification method for deodorization, dephosphorization and denitrification of wastewater and the application of the device designed by the method in the upgrading process of sewage plants, especially in urban sewage and food industry wastewater rich in Wastewater treatment of organic pollutants. Background technique [0002] China is a country seriously short of water resources. The per capita water resources are only 1 / 4 of the world's per capita. Water pollution is very serious and will continue to worsen. Pollution, red tides and eutrophication in coastal waters are increasing. [0003] Generally speaking, there are ammonia, methyl mercaptan, hydrogen sulfide, methyl sulfide, trimethylamine and other compounds in sewage. These substances will emit foul odor during sewage transportation and treatment, which will affect people's physical and ...
