Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology and relates to a column-type catalytic membrane module for degrading organic matter. Background Technology

[0002] Advanced Oxidation Process (AOP) refers to a technology whose oxidizing power exceeds that of all common oxidants or whose oxidation potential approaches or reaches the level of hydroxyl radicals (·HO). It can carry out a series of free radical chain reactions with organic pollutants, thereby destroying their structure and gradually degrading them into harmless low molecular weight organic matter, and finally into CO2, H2O and other mineral salts.

[0003] By employing a highly efficient catalyst, the generation of hydroxyl radicals is significantly enhanced, thereby increasing the removal rate of recalcitrant organic matter and reducing treatment costs.

[0004] Currently, advanced oxidation technology involves packing the catalyst inside the reactor (reaction tower). Since water containing recalcitrant organic matter needs sufficient reaction time in the reactor, the reactor requires a large footprint and a relatively high height when treating large volumes of water.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figure 1 , Figure 2As shown, a column-type catalytic membrane module for degrading organic matter includes a housing 1, a membrane core 2 inserted inside the housing 1, a catalyst 3 disposed inside the membrane core 2, an end cap 4 mounted on the right side of the housing 1 by fixing bolts 14, a support base 11 disposed on the left side of the inner cavity of the housing 1, the left end of the membrane core 2 being sealed and inserted into the support base 11, a return water chamber 111 and a product water chamber 112 disposed within the support base 11, the return water chamber 111 communicating with the interior of the membrane core 2, the product water chamber 112 communicating with the inner cavity of the housing 1, and a return water outlet pipe 9 disposed on the left side of the housing 1. The membrane core 2 is equipped with a product water outlet pipe 10 and a return water outlet pipe 9, which are sealed and inserted into the return water chamber 111. The product water outlet pipe 10 is sealed and inserted into the product water chamber 112. The end cap 4 is provided with a product water inlet pipe 6 and a return water inlet pipe 5. Both the product water inlet pipe 6 and the return water inlet pipe 5 are connected to the inner cavity of the membrane core 2. The end of the product water inlet pipe 6, the return water inlet pipe 5, the return water outlet pipe 9 and the product water outlet pipe 10 that extend out of the shell 1 is provided with a chemical dosing port 13. The chemical dosing port 13 is threaded with a cap 15. The return water inlet pipe 5 is connected to the return water outlet pipe 9.

[0019] In this embodiment, a perforated water distributor 8 is provided at the right end of the membrane core 2. The product water inlet pipe 6 and the return water inlet pipe 5 are both connected to the inlet end of the perforated water distributor 8, and the outlet end of the perforated water distributor 8 is located inside the membrane core 2.

[0020] In this embodiment, the inner wall of the housing 1 is provided with a plurality of V-shaped flow channels 7.

[0021] In this embodiment, the V-shaped flow channel 7 is made of PE material.

[0022] In this embodiment, the membrane core 2 is made of non-woven fabric, and the surface of the non-woven fabric is coated with a layer of polysulfone with a thickness of 200μm.

[0023] In this embodiment, a first sealing gasket 12 that contacts the housing 1 is provided on the left side of the end cap 4, and a second sealing gasket 16 that contacts the support base 11 is provided on the left side of the membrane core 2.

[0024] During operation, wastewater enters the perforated water distributor 8 through the product water inlet pipe 6. Simultaneously, operators can add chemicals such as hydrogen peroxide and ozone through the dosing ports 13 on the product water inlet pipe 6, return water inlet pipe 5, return water outlet pipe 9, and product water outlet pipe 10. These chemicals are then sprayed into the membrane core 2 by the perforated water distributor 8, ensuring thorough contact between the wastewater and the catalyst 3. This improves the catalyst 3's efficiency in treating wastewater. When the water containing the chemicals comes into contact with the catalyst 3, a large number of hydroxyl radicals are generated, degrading organic matter in the water. After treatment, the wastewater can enter the V-shaped flow channel 7 through the membrane core 2. Untreated wastewater... The treated wastewater cannot enter the V-shaped flow channel 7 under the action of the membrane core 2. The V-shaped flow channel 7 can increase the flow rate of the treated water, thereby improving the treatment efficiency of the catalytic membrane module for wastewater. After the treated water passes through the V-shaped flow channel 7, it can enter the product water chamber 112 and be discharged through the product water outlet pipe 6 to be transported to the next process. The untreated wastewater can enter the return water chamber 111 through the through hole between the support base 11 and the membrane core 2, and then flow back into the membrane core 2 for secondary treatment through the return water outlet pipe 9 and the return water inlet pipe 5. This ensures the treatment effect of the catalytic membrane module on wastewater, improves oxidation efficiency and effluent quality.
