Abstract

(1) The technical field to which the design belongs

This paper is a device that purifies leather wastewater and high concentration organic wastewater by combining ultrasonic wave, ozone and ultraviolet ray in wastewater.

(2) Purpose of devising

Ultrasonic wave for the purification of high concentration hardly decomposed organic wastewater or leather wastewater. ozone. In order to improve the efficacy of the reaction, that is, decomposition oxidative power, a multi-stage cascade reactor is connected to the waste water so that the waste water is upstream, and the waste water is stirred at a high speed with a reflector of ultrasonic waves in order to avoid blind spots. In addition to improving the ozone effect, the ultraviolet light is refracted to cause light gathering to improve the efficacy.

(3) constitution

When the wastewater flows in, the lowest reaction tank causes the combined reaction by the irradiation of ozone and ultrasonic waves, and the continuous reaction occurs upstream to the reactor connected up one level continuously. At this time, an ultrasonic reflector is placed to remove the blind spot of the reaction. A lamp and agitator are installed to help the ozone bubbles to react smoothly. Also, the ultraviolet light is refracted to collect the light, and a filter tank is installed to completely remove the residual sludge.

(4) effect of design

Nitrogen in refractory organic wastewater or leather wastewater. sign. Heavy metals such as chromium are contained, so when it enters rivers or the sea, eutrophication occurs and green algae or red tide occur, causing fish to be killed.

Organics from leather wastewater and high concentration organic wastewater. nitrogen. sign. Heavy Metal (Chrome, etc.) Removal Device {.}

-Treatment of BOD, COD, Sludge, Nitrogen, Phosphorus, Heavy Metal, etc According to the purification theory of the complex oxidation method, the concept of treatment with the biological process is completely different. The biological process is the ingestion of organic matter by microorganisms, and the complex treatment method is that the organic matter is rapidly decomposed and oxidized into water and carbon dioxide.

Organic matters are classified into high molecular weight organic matters and low molecular weight organic matters. Among the low molecular weight organic matters, they are composed of highly polarized low molecular weight organic matters (hard-decomposable materials). So, ozone alone is difficult to decompose organic matters into water and carbon dioxide. Low molecular organic materials (hardly decomposable substances), such as acids, remain, and when ultrasonic waves are irradiated in water to completely decompose such substances, an uncountable fine bubble is generated. As the organic matter is rapidly decomposed, it is rapidly oxidized by ozone and ultraviolet rays, and the small bubbles of ultrasonic waves break up the large bubbles of ozone, thereby improving ozone efficiency and proportionally reducing undestructed ozone (waste ozone). In this way, a combination of ultrasonic waves, ozone and ultraviolet light was handled, and a low-molecular organic substance with high polarity was completely decomposed into water and carbon dioxide by a heterogeneous reaction, and the suspended solids were completely removed through a special filtration function.

In order to realize this, before the incoming waste water is introduced into the reactor, the waste water after removing the suspended solids as much as possible is allowed to flow into the reactor vessel (2) and the waste water is upstream. At the bottom of each reactor, an ozone acid pipe (3) and an ultrasonic vibrating plate (4) are installed, and an ultrasonic reflector (5) is placed to remove blind spots during ultrasonic irradiation, so that the ultrasonic waves interfere with each other to increase the efficacy, Equipped with agitating blades (10) to form a lot of bubbles in the waste water, to increase the contact area with ozone to cause a smooth reaction, and then to remove the suspended solids by the filtration step (6) and to irradiate the discharge tank with ozone It consists of a device that maximizes treatment efficiency by rotating the wastewater to refract ultraviolet light. All.

1. Among the non-degradable organic-inorganic wastewaters, such as leather wastewater, leachate water and livestock wastewater, the odor and color are so strong that it becomes a huge source of pollution when it enters the river or the sea. It also contains phosphorus, which leads to an area where organisms cannot live, and it can effectively remove it.

Claims (1)

By connecting a cascade reactor, the waste water is upstream, and the ultrasonic wave and ozone are continuously contacted. At this time, the ozone acid pipe (3) and the ultrasonic vibrating plate (4) are installed at the bottom of the reactor, eliminating the blind spot of the ultrasonic wave and interfering with the ultrasonic wave. In order to improve this, an ultrasonic reflector (5) is placed, and at this time, a filtration tank (6) for filtration of the residual suspended solids is completely placed, and the treated water is finally introduced into the discharge tank (11) to treat some untreated residual organic matter.
