AI Technical Summary

Problems solved by technology

This can be attributed to two reasons: (1) The consolidation technology of titanium dioxide and other metal oxide powders has not been resolved
During the photocatalytic degradation of titanium dioxide and other metal oxide powders, it is easy to cause problems such as obstruction of light radiation in the reactor and loss of powder.
Judging from the situation of literature retrieval, there have been many reports at home and abroad on the preparation of metal oxide composite catalytic materials using zeolite, glass, single crystal silicon, conductive glass, etc., but the preparation costs of these methods are high. There are still problems in the reactor that cause light radiation to be blocked, and there is also the problem of powdering due to friction between granular materials
(2) The photocatalytic degradation rate of titanium dioxide and other metal oxide powders is slow, mainly because the relative concentration of the substances to be degraded on the surface of titanium dioxide powder is small
Applying this technology, a preparation method and application of a composite paper-based material with the function of adsorbing and degrading organic matter was invented (patent application number: 200810070938.5). It effectively solves the problems of blocked light radiation caused by titanium dioxide and other metal oxide powders, and also solves the high preparation cost and granular materials of titanium dioxide and other metal oxide composite catalytic materials prepared by using zeolite, glass, single crystal silicon, conductive glass, etc. as carriers. The problem of powdering due to friction

Embodiment 1

[0019] Step 1: Prepare a composite paper-based material according to the patented technology of "A Preparation Method and Application of a Composite Paper-based Material with the Function of Adsorbing and Degrading Organic Matter (Patent Application No. 200810070938.5)". The material is corrugated.

[0020] Step 2 Follow the attached figure 2 The degradation box is made of ABS engineering plastic board, and is made into a box with a unilateral door with a net depth of 600 mm, a net width of 450 mm, and a net height of 800 mm.

[0021] Step 3: Take 25×25×580mm strip planks, place them in the box from top to bottom, and set 4 pairs to fix them on both sides of the box according to the distances of 150mm, 80mm, 80mm, and 80mm from the upper surface. Reservoir rail (5) and degradation tank rail (10) on the wall.

[0022] Step 4: Install the ultraviolet light tube (6) on the back and side of the box on the middle contour line of the upper and lower guide rails.

[0023] Step 5:...

Embodiment 2

[0033] On the basis of Example 1, light up the ultraviolet lamp (6), and pour a mixture containing 50 mg / L of styrene-acrylic emulsion and 50 mg / L of phenol into the waste liquid inlet funnel (1) on the upper bottom of the cuboid box. 500ml simulated waste liquid. Control the lower dropper (3) with a flow rate control in the upper liquid storage tank (2), so that the waste liquid will drop in about 3 hours.

[0034]After all the waste liquid has been dripped in 3 hours and enters the lower liquid storage tank (12), start the water pump (13) to pump back the waste liquid in the lower liquid storage tank (12) to the upper liquid storage tank (2) for In the second round of degradation, samples are taken to measure the concentration of waste liquid in the lower liquid storage tank (12). If the expected degradation target is not reached, a third round of degradation can be performed. The waste liquid that has reached the expected degradation target is discharged outward from the w...

Abstract

The invention relates to a degradation box with functions of adsorbing and degrading organic waste liquor. The degradation box comprises a box body, a composite paper base material, a degradation tank, a liquor storage tank, an ultraviolet light source and a waste liquor pumpback system, wherein the box body is of a cabinet structure; the liquor storage tank is divided into an upper liquor storage tank and a lower liquor storage tank, wherein the upper liquor storage tank is positioned at the upper part in the box body, and the lower liquor storage tank is positioned at the lower part in the box body; the degradation tank is positioned between the upper liquor storage tank and the lower liquor storage tank; the pumpback system is positioned on the outer side surface of the box body; the composite paper base material is positioned in the degradation tank; and the ultraviolet light source is positioned in a back plate of the box body. By utilizing the degradation box provided by the invention, the problems of optical radiation blockade caused by powder of metal oxides, such as titanium dioxide, and the like are effectively solved, and the problems that a composite catalysis material of metal oxides, such as titanium dioxide, and the like has high preparation cost and is pulverized due to the friction among particles are also solved. In addition, the degradation box has an adsorption effect on low-concentration organic matters, greatly-improved photocatalytic degradation speed and commercialized application prospect.

Description

technical field [0001] The invention relates to a simple degradation box for organic waste liquid, in particular to a simple box body degradation box containing a composite material with photocatalytic function and capable of absorbing and degrading common organic waste liquid in chemical laboratories. Background technique [0002] In recent years, toxic and harmful waste liquids produced in laboratories of universities and scientific research institutes have attracted increasing attention. The chemical laboratory mainly conducts intermittent experiments, the types of experiments are diverse and complex, and the composition of the experimental waste liquid is also quite complicated. The amount of experimental water is unstable, and the amount and composition of the discharged wastewater varies greatly with time, making collection and storage more troublesome. Due to these characteristics of laboratory waste, at present, only a few colleges and universities in China collect e...
