Embodiment 1

[0025] Embodiment 1 specifically describes the overall composition and wastewater treatment process of the mobile rapid wastewater treatment equipment of the present invention in conjunction with the accompanying drawings.

[0026] Figure 1~3 A schematic diagram of the overall composition of the mobile rapid wastewater treatment equipment is given. In the figure, 1 is the regulating pool, 2 is the intermediate pool, 3 is the micro-electrolysis reaction column, the micro-electrolysis reaction column 3 is added with the applicant’s self-made regularized micro-electrolysis packing, 4 is the ozone catalytic oxidation reaction column, and the ozone catalytic oxidation reaction column 4 Add the applicant's self-made silica gel carrier catalyst loaded with iron and manganese in advance, 5 is the activated carbon adsorption column, 6 is the ozone generator, 7 is the ozone adsorption tank, 8 is the waste water inlet pump, 9 is the micro electrolysis reaction column inlet pump, 10 is t...

Embodiment 2

[0031] The making of embodiment 2 regularized micro-electrolysis packing

[0032] The regularized micro-electrolysis packing added in the micro-electrolysis reaction column 3 is self-made in the laboratory. The production of structured micro-electrolytic fillers is to mix iron filings, manganese powder, activated carbon powder and clay at a mass ratio of 5:0.7:1:3.3, add a small amount of deionized water as a binder, and shake the mixture into granules , when the particle size of the filler reaches 3-10mm, put the filler in an oven and dry at 50°C for 2 hours. After drying, spread a layer of fine sand on the surface of the filler to isolate the air and prevent oxidation, then put it into a muffle furnace and heat and roast at 300°C for 3 hours, and then the regular micro-electrolytic filler is obtained after cooling.

[0033] According to the results of laboratory simulation experiments, the regularized micro-electrolysis filler of the present invention can remove more than 7...

Embodiment 3

[0034] Preparation of the silica gel carrier catalyst of embodiment 3 loaded iron and manganese

[0035]In the ozone catalytic oxidation reaction column 4, add in advance the laboratory-made silica gel carrier loaded with iron and manganese as a catalyst. The preparation process of the new catalyst is as follows: first, the carrier silica gel purchased is cleaned, and after drying, the carrier silica gel is immersed in the first In the 10% nitrate solution in which the mass ratio of dissolved Mn and Fe is 3:1, 1.20Kg of carrier silica gel and 2.5L of nitrate solution have been weighed, and then immersed at 40°C for at least 24h. Take it out and drain it, then put it in an oven at 85°C and bake it for about 8 hours, take it out and put it in a muffle furnace, adjust it to 450°C, and bake it for 6 hours. After cooling to room temperature naturally, rinse it with distilled water until almost Until no metal ions are detected, place it in a ventilated place to dry for later use.

Abstract

The invention relates to removable rapid waste water treatment equipment, and belongs to the technical field of waste water treatment equipment. The removable rapid waste water treatment equipment is characterized in that the structure comprises a regulating tank (1), a middle water tank (2), a micro-electrolysis reaction column (3), a catalytic ozonation reaction column (4), and an activated carbon adsorption column (5). The micro-electrolysis reaction column (3) is filled with a regularized micro-electrolysis filter, the catalytic ozonation reaction column (4) is filled with a ferro-manganese-loaded silica-gel carrier as a catalyst, the catalytic ozonation reaction column is connected with an ozonator (6) and an ozone adsorption tank (7), and the activated carbon adsorption column (5) is provided with a return pipe connected with the regulating tank (1). The removable rapid waste water treatment equipment is designed to arrange on a bearing plate with wheels, and is powered by using a diesel generator, has the advantages of high maneuverability, cheap fillers, simple structure, good treatment effects and the like, can effectively remove COD and organic matters in high-concentration waste water, and has higher utilization value when a sudden environmental pollution event of the high-concentration waste water occurs.

Description

technical field [0001] The invention relates to high-concentration wastewater treatment equipment, in particular to an integrated mobile rapid treatment device using a combined treatment process of micro-electrolysis technology, ozone advanced oxidation technology and activated carbon adsorption technology. Background technique [0002] In recent years, with the sustained and rapid development of my country's economy and society, my country's environmental problems have become increasingly serious, and environmental pressure has increased. Many industrial and mining enterprises have serious illegal discharges. The sewage discharged by these industrial enterprises often has a high concentration and contains a lot of pollution. Serious organic pollutants, especially the sewage discharged by some printing and dyeing, pharmaceutical, metallurgical, chemical, coking and other enterprises contain highly toxic organic pollutants, which have caused serious impact on the environment. ...
