Abstract

A multi-phase-effect waste water deep treatment reactor comprises a pre-positioned reactor and a main reactor, the pre-positioned reactor comprises an inlet and an outlet, at least two static mixers are connected between the inlet and the outlet through a connection pipeline, a pH measurement device is arranged on the pipeline between the static mixers, upstream pipelines of the static mixers are provided with filling ports respectively, the main reactor is a hollow reaction tower, the bottom of the tower is provided with a cyclone inlet water distributor, the upstream portion of the cyclone inlet water distributor is provided with a filling port, at least two catalyst layers, a set of baffle plates, an aerator and spraying defoaming devices are arranged inside the tower sequentially from bottom to top, a high-frequency catalyzing system is arranged between the catalyst layers, a water outlet device is arranged at the top of the tower, and the outlet of the pre-positioned reactor is connected with the cyclone inlet water distributor of the main reactor. Through the gas, solid and liquid multi-phase environments and efficient processing modes of advanced oxidation, catalytic oxidation and even mixing, the CODCr removal rate is high.

Description

technical field [0001] The application relates to the field of waste water environmental protection treatment, in particular to a heterogeneous reactor for advanced treatment of waste water. Background technique [0002] With the implementation of the "Water Pollutant Discharge Standard for Pulp and Paper Industry (GB3544-2008)", the state has put forward higher requirements for the discharge of papermaking wastewater. It is difficult to meet the standard by simply using physical and chemical + biochemical secondary treatment methods. Advanced treatment of wastewater is generally required. The advanced treatment technologies that have been applied or are about to be applied at present mainly include: flocculation precipitation method, membrane separation method, electrochemical method, magnetization pretreatment, biological enzyme biogenetic engineering, compound biomimetic enzyme, advanced oxidation method (such as ozone oxidation, light oxidation, etc.) Catalysis, Fenton ...
