Three-dimensional ecological deodorization, phosphorus and nitrogen removal method, device and application

Abstract

A three-dimensional ecological deodorant dephosphorization denitrification method, wherein in a sewage treatment system, groups of plants (2) are suspended in a reaction tank, branches and leaves of the aquatic plants form an isolation purification layer capable of adsorbing odor and preventing outward diffusion of odor, and at the same time, roots and stems of the aquatic plants in the sewage serve as an ecological filler and adsorb and degrade microorganisms and adsorb odor, thereby achieving the purpose of deodorant dephosphorization denitrification of wastewater. A deodorant dephosphorization denitrification apparatus designed according to the method and a use thereof in an SBR process, an A / O process, an A2 / O process, an AB process, an oxidation ditch process, an MBR process, and a MUCT process. The three-dimensional ecological deodorant dephosphorization denitrification method is an ecological low-cost treatment method that uses an original sewage treatment system as the main measure and plants for purifying organics as an aid measure. The three-dimensional ecological deodorant dephosphorization denitrification method can be used to upgrade sewage treatment plants of various processes, and can achieve the greatest degree of biodegradation of pollutants.

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 ...
