Description

Technical Field

[0001] The utility model relates to the technical field of water pollution control and water treatment, in particular to a treatment device for waste water containing oil and suspended matter. Background Art

[0002] With the continuous development of the environmental protection industry, there are requirements for intensification and productization of technologies and processes, and at the same time, there is greater tolerance for investment and operating costs.

[0003] For example, the high-suspended high-oil wastewater in the wastewater treatment sector, such as catering kitchen and garbage leachate, has the characteristics of high organic matter content, difficult biochemical treatment, and long pre-treatment process. At the same time, the high-suspended high-oil wastewater is accompanied by a variety of pollutants, which are not easy to separate. If it is treated by evaporation and other methods, there will be disadvantages such as easy corrosion of equipment. Therefore, it is necessary to conduct deeper exploration on the deep treatment of high-suspended high-oil wastewater and even the zero-emission process.

[0004] Tubular membrane products are a highly efficient membrane separation technology. Tubular membranes have high requirements for influent water quality. When treating some water sources containing high concentrations of sediment, they are easily affected by membrane surface fouling, causing the membrane flux to drop rapidly, thereby reducing the service life of the membrane. In addition, the cleaning is complicated, and it is impossible to treat high-suspended and high-oil wastewater. However, the tiny pore size of the tubular membrane gives the tubular membrane extremely high selectivity and transmission rate for a variety of solutes. Tubular membranes can efficiently separate pathogens, cells, microorganisms, ions, and organic matter in the solution. Therefore, if the impact of membrane surface fouling can be reduced, the scope of use and application scenarios of tubular membranes will be greatly improved. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The utility model aims to provide a treatment device for wastewater containing oil and suspended matter, so as to solve the problems existing in the prior art, slow down the clogging cycle of the tubular membrane, prolong the service life, and realize modularization and convenient operation.

[0023] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0024] like Figure 1-Figure 3 As shown, this embodiment provides a treatment device for wastewater containing oil and suspended matter, which is mainly aimed at high-suspended and high-oil wastewater in wastewater treatment sections such as kitchen waste and garbage leachate, including a tubular membrane 1, a physical treatment unit 3 and a temperature control element. The power supply unit 2 is electrically connected to the physical treatment unit 3. The physical treatment unit 3 includes an oscillation element and a temperature control element. The power supply unit 2 is used to provide power for the oscillation element and the temperature control element, and the current is controllable. The tubular membrane 1 is used to filter the wastewater passing through. The oscillation element is installed on the tubular membrane 1 and is used to make the wastewater oscillate inside the tubular membrane 1 and generate micro-nano bubbles. The temperature control element is connected to the tubular membrane 1 and is used to control the wastewater in the tubular membrane 1 to be in a temperature range of 50°C-70°C. Through the cooperation of the oscillation element and the temperature control element, the oil in the wastewater is kept in a discrete state, and the effect of degrading some organic pollutants is achieved through the physical action of the microbubbles. Physical methods are used in conjunction with tubular membrane 1 to treat high-suspended high-oil wastewater, thereby maintaining a higher flux of the tubular membrane 1 per unit area, reducing the occurrence of blockages, reducing the number of offline cleaning times, and increasing the service life. It can effectively deal with high-suspended high-oil wastewater in wastewater treatment sectors such as restaurant kitchen and garbage leachate, and expand the application scope and usage scenarios of tubular membrane 1, which can treat high-suspended high-oil wastewater more efficiently and conveniently.

[0025] Specifically, there are multiple groups of oscillating elements, which are arranged in sequence along the length direction of the tubular membrane 1. Those skilled in the art can also reasonably combine the number and arrangement positions of the oscillating elements and the temperature control elements according to the concentration of the treated pollutants to meet the use requirements.

[0026] The oscillating element is an ultrasonic generator, and the ultrasonic generator is a variable-length modular type. When the ultrasonic generator is turned on, it can emit ultrasonic waves to the liquid, causing the liquid to be stretched to generate negative pressure. When the negative pressure is controlled to be lower than the cavitation pressure of the liquid, micro-nano bubbles are generated, which can remove some organic pollutants.

[0027] The generating end of the ultrasonic generator is made of titanium alloy.

[0028] This embodiment further comprises two clamping rings 4 , which can be buckled on the outer circumference of the tubular membrane 1 and connected, and the oscillating element and the temperature control element are installed on the outer wall of the clamping ring 4 .

[0029] The two clamping rings 4 are connected by a buckle or a bolt.

[0030] The temperature control element is annular, mounted on the clamp ring 4, and arranged around the outer periphery of the tubular membrane 1. As a preferred solution, the temperature control element can be a jacket. The temperature control element can keep the high-oil wastewater in the tubular membrane 1 at a temperature range of 50°C-70°C, maintain the discrete state of oil in the wastewater, and make it difficult for oil droplets to be adsorbed and adhered to the ultrafiltration membrane of the tubular membrane 1. In conjunction with the ultrasonic generator, nano-micro bubbles are formed through the liquid phase, thereby achieving the effect of degrading some organic pollutants.

[0031] The present invention uses specific examples to illustrate the principle and implementation of the present invention. The above examples are only used to help understand the method and core idea of ​​the present invention. At the same time, for those skilled in the art, according to the idea of ​​the present invention, there will be changes in the specific implementation and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
