Embodiment 1

[0080] Embodiment 1: the method for described open type sewage treatment, comprises the steps:

[0081] (1) For sewage with different application occasions and different pollution degradation targets, it is necessary to conduct preliminary water body detection and small-scale treatment tests. After obtaining the preliminary detection and test data, optimize and adjust the process parameters and even optimize the catalyst compatibility. Significantly improve the multi-physics-enhanced oxidation decomposition water purification device's ability to purify and treat target sewage.

[0082] (2) According to the sewage period detection and test data of the first target, select several suitable multi-physics field enhanced oxidation decomposition water purification devices, and prepare transformer and rectifier equipment, power supply, oxygen cylinder, air supply pipe, air supply pump or oxygen supply pump .

[0083] (3) Prepare a cofferdam 21, or a natural pool, or close a section ...

Embodiment 2

[0086] Embodiment 2: the method for described closed sewage treatment, comprises the steps:

[0087] (1) Sewage is first introduced into the cleaning machine 28 through the sewage inlet pipe 26 and the water pump 27 to remove foreign matter in it, so as to get the waste water removed.

[0088] (2) Introduce the de-impurity sewage into the sand removal tank 29 to remove the silt in it, so as to obtain silt-free sewage.

[0089] (3) Introduce the silt-free sewage into the aeration tank 31 with the pipeline 30, and use the multi-physics field enhanced oxidation decomposition water purification device provided in the aeration tank to carry out 2 to 3 cycles of the silt-free sewage entering the tank After the treatment, multiple physical field enhanced oxidation and decomposition water are introduced into the precipitation tank 33 for precipitation.

[0090] (4) Physical Field Enhanced Oxidation The sedimentation time of the decomposed water in the sedimentation tank is 5-8 hours,...

Embodiment 3

[0093] Embodiment 3: the method of described open type treatment sewage and closed treatment sewage can be used in combination, as with the cofferdam of embodiment 1, or natural pool, or close a section of river surface to be treated to form storage sewage pool and this in the pool The inventive device replaces the aeration tank of Example 2. Or introduce step (5) of embodiment 2 etc. in embodiment 1. So I won't repeat it any more.

[0094] In a word, the present invention combines photocatalyst, electrolytic ionization, magnetic drive and aeration oxidation technology to purify sewage, has simple structure, convenient operation, low energy consumption, high efficiency, less residual sludge, and can remove nitrogen, phosphorus, etc. Advantages of inorganic substances, recovery of phosphorus and inorganic substances, and reuse of treated water.

Abstract

The invention relates to a multi-physical field enhanced oxidative decomposition water purification device and a pollution control method thereof. The device provided by the invention consists of a shell, an outer photocatalyst, an inner photocatalyst, a light source upper support, a light source lower support, a light source, an electromagnetic spiral coil, an aeration head and an aeration head air inlet. The pollution control method comprises the following steps: introducing air or oxygen, and mixing the air or oxygen with sewage through the aeration head to form an aeration-like water flow which enters the outer photocatalyst of the device provided by the invention in a circulating manner to be subjected to direct or indirect electrochemical reaction with light, electricity, magnetism and nano-catalytic materials to remove pollutants in sewage. The multi-physical field enhanced oxidative decomposition water purification device provided by the invention integrates the photocatalysts, electrolytic ionization, magnetic driving and aeration oxidation technologies for sewage purification, has the advantages of simple structure, convenience in operation, low energy consumption, high efficiency and less excess sludge amount, can remove inorganic substances such as nitrogen and phosphorus, and achieves recovery and treatment of phosphorus and inorganic matter and recycling of water.

Description

technical field [0001] The invention belongs to a multi-physical field enhanced oxidation decomposition water purification device and a pollution control method thereof. Background technique [0002] Water is an important resource for human survival, and clean fresh water is the basic guarantee for people to obtain normal production and life. Most of the sewage is composed of many soluble harmful compounds. However, whether it is brackish water, saline water in nature, or the wastewater discharged by human production and life, it also contains many soluble harmful compounds. Therefore, obtaining a technology and device that can directly and efficiently decompose or reduce soluble harmful compounds in water is of great significance to the survival and development of human beings. [0003] There are many ways to treat sewage, such as distillation, electrodialysis, reverse osmosis, etc., but these methods have the disadvantages that sewage needs to be pretreated first, special...
