Problems solved by technology

[0006] In view of the problems existing in the prior art, the purpose of the present invention is to provide a rotary microwave wastewater treatment device, which uses activated carbon to load FeSO 4 In the way of microwave catalytic reaction, oxygen and other oxidizing gases are introduced. The whole experimental device is designed as a rotary type. After adsorption and catalytic reaction of organic waste water, the catalyst can be regenerated, avoiding the high cost of constantly replacing the catalyst. and problems that lead to inefficiencies

Embodiment 1

[0041] Such as figure 1As shown, a rotary microwave wastewater treatment device includes a housing, a reaction chamber, and a microwave generator 7 arranged on one side of the reaction chamber. The interior of the housing is divided into two symmetrical parts by a partition, and the adsorption chamber and the degradation and regeneration chamber, the upper and lower ends of the housing are provided with an air inlet 1, an air outlet 5, a liquid inlet 2 and a liquid outlet 6, and the air inlet 1 and the air outlet 5 are located on the same side of the partition, And be arranged at different ends of the housing, the liquid inlet 2 and the liquid outlet 6 are also located on the same side of the partition, and are arranged at different ends of the housing; the reaction chamber is located in the middle of the housing, and the reaction chamber is set There is a catalyst layer, and the catalyst layer can rotate.

[0042] The catalyst layer is a catalyst plate, the catalyst plate is...

Embodiment 2

[0055] The catalyst layer is a fine network structure, filled with catalyst, and the catalyst is activated carbon supported FeSO 4 .

[0056] The wall of the housing where the reaction chamber is located is fixed, and the catalyst plate can rotate relative to the housing driven by the motor and the rotating shaft.

[0057] Firstly, the organic liquid enters through the liquid inlet 2, passes through the liquid distributor 3, and evenly flows through the activated carbon adsorbent. After the activated carbon is saturated, the device is rotated, the microwave generator 7 is turned on, and the oxidizing gas is introduced to catalyze the oxidation of the organic matter. The gas contains a relatively large amount of water vapor. After the gas is cooled by the gas cooler 4, the gas-liquid is separated. After the oxidation process is completed, the nitrogen protective gas is introduced from the air inlet 1 to regenerate the activated carbon. In this way, you can get A nearly continu...

Abstract

The invention discloses a rotary type microwave wastewater treatment device. The device comprises a casing, a reaction chamber and a microwave generator arranged on one side of the reaction chamber, wherein the inside of the casing is separated into two symmetric parts by a partition board, and the two parts comprise an adsorption chamber and a degradation and regeneration chamber; a gas inlet, a gas outlet, a liquid inlet and a liquid outlet are arranged at the upper end and the lower end of the casing, the gas inlet and the gas outlet are located on the same side of the partition board and arranged at different ends of the casing, and the liquid inlet and the liquid outlet are also located on the same side of the partition board and arranged at different ends of the casing; the reaction chamber is located in the middle of the casing, and a catalyst layer is arranged in the reaction chamber and can rotate. By means of the reaction principles of organic matters under microwave catalysis, a catalytic reaction of the organic matters and a regeneration reaction of activated carbon are combined through the heating property of the microwaves, the activated carbon is saved, and energy is saved. The overall removal efficiency of organic matters in wastewater can reach 90% or above.

Description

technical field [0001] The invention belongs to the field of waste water treatment, and specifically relates to a rotary microwave waste water treatment device. The device is mainly aimed at enterprises producing high-concentration organic waste water. The principle of microwave catalytic reaction is used in the device, and the characteristics of the rotary type can be used for high-concentration organic matter. Wastewater is effectively treated. Background technique [0002] With the continuous development of industry, the types and discharge of organic wastewater are increasing, and the composition of organic wastewater is complex and difficult to treat, which has become a major problem in wastewater treatment. Organic waste water pollutes water bodies very seriously. Since my country is a country with very small water resources per capita, which is only a quarter of the world average, the protection of water resources is very important. [0003] At present, there are rou...
