Iron-carbon pipe component capable of purifying waste water, integrated magnetoelectric oxidation biological filter chamber and application system

Abstract

An iron / carbon nanotube component capable of treating wastewater comprises a central tube with a plurality of pores on the tube wall, wherein the central tube arranged into the inner cavity of an outer sleeve is coated with an electrode material layer on the outer wall thereof, having the inner cavity thereof communicated with a water inlet port, and provided at the central position thereof with an anode tube connected with an external power supply; and the upper and the lower ends of the outer sleeve are sealed and respectively provided thereon with a water outer port and a wastewater drainage port. The invention also provides a magnetoelectric oxidation biological filter tank containing the above iron / carbon nanotube component and integrating catalytic oxidation / reduction reaction and precipitation, biological phosphorus and nitrogen removal, filtration and sludge discharging, comprising a tank body and a total water inlet tube and a total water outlet tube arranged on the tank body, wherein a tank body bracket and an iron / carbon nanotube supporting frame are arranged inside the inner cavity of the tank body, iron / carbon nanotube components arranged in rows are arranged on the tank body bracket, and a water distribution tube communicating with the total water input tube is arranged on the iron / carbon nanotube supporting frame; and an aeration plate and a filtering filler are arranged among iron / carbon nanotube components. The inventive iron / carbon nanotube component can be used for treating electroplating wastewater, concentrated fluid generated from nanofiltration membrane or RO membrane, dyeing wastewater, pharmaceutical wastewater and other wastewater that is difficultly treated by using biological method, and the operating cost and floor space are half of those in conventional process, so that the inventive iron / carbon nanotube component has wide application prospect.

Description

【Technical field】 [0001] The present invention relates to the field of wastewater purification, in particular to a method that can be used for refractory biochemical wastewater, electroplating wastewater, nanofiltration or RO membrane to produce concentrated liquid, printing and dyeing wastewater, etc. The purification treatment element used in the treatment process of mud in one device and discharge up to standard or reuse treatment - iron-carbon tube and the integrated magnetoelectric redox biological filter and application system containing the iron-carbon tube. 【Background technique】 [0002] In the field of wastewater treatment, wastewater that is difficult to biochemically treat generally includes petrochemical, pharmaceutical, printing and dyeing, paint, electroplating, leather, landfill leachate and other wastewater. At present, there are many ways to treat electroplating wastewater at home and abroad. For example, the chemical method is relatively mature, but the pr...

Problems solved by technology

[0006] The applicant has done a series of studies on the above-mentioned problems in the prior art, such as: "A Wastewater Purification Method and Its Magnetized Coagulator Integrated Equipment" (Patent No.: 200310117654.4, Application Date: December 31, 2003), " Magnetized Photocatalytic Integrated Sewage Recycling Device" (Patent No.: 200520056849.7, application date April 12, 2005), "A Photoelectromagnetic Integrated Advanced Wastewater Oxidation Method and Device" (Patent Application No.: 2007100731666, application date 2007 April 20), although the above-mentioned patent documents involve magnetic coagulation, electrocatalytic oxidation, UF ultrafiltration, automatic sludge dehydration and other processes, they cannot solve the problem of backwashing concentrated liquid treatment and electroplating wastewater treatment and reuse, making the wastewater Processing is subject to certain restrictions

In addition, the above-mentioned treatment devices occupy a large area and cannot realize the integrated work of catalytic reduction reaction and precipitation, biological phosphorus and nitrogen removal, filtration, and sludge discharge. The processes of precipitation, biological phosphorus and nitrogen removal, filtration, and sludge discharge must be carried out In addition, the implementation in the pool will undoubtedly increase the cost of engineering manufacturing and use
