[0024] The present utility model has developed a water treatment device for emergency treatment of dispersed water with excessive iron, manganese, and zinc ions. The device has a skid-mounted structure, with a highly integrated system, low investment cost, small floor area, short production cycle, and rapid response to the water treatment site. At the same time, the operating cost is low, the daily operation and maintenance management requirements are low, and the degree of intelligence is high, which can truly achieve unattended operation.

[0025] The structure of a water treatment device for emergency treatment of dispersed water with excessive suspended matter, iron, manganese, and zinc ions provided by the present utility model is as Figure 1 shown, and it includes an ultrafiltration system, an adsorption filter media system, and a disinfection system 11 connected in sequence. The ultrafiltration system includes a water inlet pipeline 1, an ultrafiltration membrane 2, an ultrafiltration membrane tank 3, a product water pump 4, an intermediate water tank 5, a blower 6, a backwash pump 7, etc.; the adsorption filter media system includes an adsorption filter media inlet water pump 8, an adsorption filter media tank 9, an adsorption filter media backwash pump 10, etc. The ultrafiltration system, the adsorption filter media system, and the disinfection system are integrated on an integrated frame 13.

[0026] The water inlet pipeline 1 is connected to the ultrafiltration membrane tank 3. The raw water to be treated enters the ultrafiltration membrane tank 3 through the water inlet pipeline 1. An ultrafiltration membrane 2 is arranged in the ultrafiltration membrane tank 3. The product water outlet of the ultrafiltration membrane 2 is connected to the product water pump 4 through a pipeline. The raw water to be treated in the ultrafiltration membrane tank 3 is filtered by the ultrafiltration membrane 2 to remove suspended matter and colloid under the suction of the product water pump 4 and then enters the intermediate water tank 5.

[0027] This ultrafiltration device operates in an intermittent water production mode. The main sequence during operation is water production - air washing - water washing - drainage - water injection - water production. After water production for a certain period, it stops, the water production pump 4 stops running, and it enters the air washing stage. The fan 6 is connected to the aeration port of the ultrafiltration membrane 2. During the air washing stage, the fan 6 aerates the ultrafiltration membrane 2 through a pipeline to achieve air scrubbing of the ultrafiltration membrane 2. After air washing is completed, the fan 6 stops running and it enters the water washing stage. The water outlet of the backwashing pump 7 is connected to the backwashing port of the ultrafiltration membrane 2 through a pipeline, and the water inlet of the backwashing pump 7 is connected to the intermediate water tank 5 through a pipeline. During the water washing stage, the backwashing pump 7 pumps the water in the intermediate water tank 5 (i.e., the water after the ultrafiltration membrane 2 filters suspended solids) into the ultrafiltration membrane 2 to achieve water backwashing of the ultrafiltration membrane 2. After water backwashing is completed, the backwashing pump 7 stops, the system automatically drains, the water inlet pipeline 1 automatically fills with water, the water production pump 4 is turned on, and water production resumes.

[0028] The water produced by the ultrafiltration system enters the intermediate water tank 5, and the intermediate water tank 5 also serves as the water inlet tank for the adsorption filter media system. The water inlet of the adsorption filter media inlet pump 8 is connected to the intermediate water tank 5, and the adsorption filter media outlet pump 8 is connected to the adsorption filter media tank 9. During operation, the adsorption filter media inlet pump 8 pumps the water in the intermediate water tank 5 (i.e., the water after the ultrafiltration membrane 2 filters suspended solids) into the adsorption filter media tank 9 to remove metals such as iron, manganese, and zinc in the raw water. The adsorption filter media system also operates in an intermittent mode. After water production for a certain period, the adsorption filter media inlet pump 8 stops running, the adsorption filter media backwashing pump 10 is turned on. The water inlet of the filter media backwashing pump 10 is connected to the external final water production pool, and the water outlet of the filter media backwashing pump 10 is connected to the adsorption filter media tank 9 to backwash the adsorption filter media tank 9. After backwashing for a certain period, the adsorption filter media backwashing pump 10 stops, the adsorption filter media inlet pump 8 is turned on, and water production resumes.

[0029] The water produced by the adsorption filter media system is disinfected by the disinfection system 11 and then meets the discharge standards. The disinfection system 11 mainly disinfects with sodium hypochlorite to remove Escherichia coli in the raw water. The pipeline of the disinfection system 11 is connected to the water production pipeline.

[0030] The device of the present utility model has a high degree of intelligence, can achieve unattended operation, and the entire operation process is controlled by the PLC (programmable logic controller) in the electric control system 12.

[0031] This system is highly integrated. All devices, systems, and units are integrated on the integrated framework 13, which is convenient for transportation, occupies a small area, and has a low investment cost.

[0032] This equipment adopts the advanced ultrafiltration + adsorption filter media + sodium hypochlorite disinfection process, supplemented by a sterilization and disinfection function. The raw water enters the system through a lift pump and first enters the submerged ultrafiltration part to remove impurities in the raw water. The submerged ultrafiltration of this equipment operates in an intermittent water production mode, and the main operation sequence during the operation period is water production - air washing - water washing - discharge - water injection - water production. According to the on-site water quality and operation conditions, it is necessary to chemically clean the submerged ultrafiltration membrane regularly. The designed water production rate of the ultrafiltration system is 90% - 95% (to be determined according to the on-site situation). The water produced by the ultrafiltration enters the adsorption resin system to adsorb and remove iron, manganese, and zinc in the water. Usually, it operates continuously and is backwashed once every 2 - 3 days (depending on the on-site situation). The water output from the resin system enters the contact tank (the clean water tank can be used concurrently) after being disinfected by sodium hypochlorite (in the form of pipeline mixing). The residence time in the contact tank needs to be ≥ 30 minutes to enable sodium hypochlorite to fully disinfect bacteria and other microorganisms.

[0033] In summary, the present utility model has developed a water treatment equipment for dispersed and emergency iron, manganese, and zinc ion - exceeding water supply. The equipment has a skid - mounted structure, which is welded by 5# square steel and angle steel. All the equipment in the system is installed on the skid - mounted structure. The system is highly integrated, with low investment cost, small floor area, short production cycle, and rapid response to the water treatment site. At the same time, the operation cost is low, the daily operation and maintenance management requirements are low, and the degree of intelligence is high, which can truly achieve unattended operation. This equipment adopts the advanced ultrafiltration + adsorption filter media + sodium hypochlorite disinfection process, supplemented by a sterilization and disinfection function, and can effectively remove suspended solids, iron, manganese, zinc and other metal elements, as well as Escherichia coli in the raw water, ensuring the water quality of the effluent.
