Description

Technical Field

[0001] The invention relates to the technical field of wastewater treatment, in particular to a treatment device for hot spring tail water and a treatment process thereof. Background Art

[0002] With the rapid growth of my country's economy, people's living standards have been continuously improved, and the pursuit of quality of life has become higher and higher. Hot spring water is rich in sulfur and other trace elements, which has a good therapeutic effect on skin diseases, rheumatoid arthritis, nerve paralysis, etc. Hot spring baths are also beneficial to blood circulation, promote functional recovery of patients with cerebral thrombosis, and have a significant effect on lowering blood pressure. Therefore, hot spring therapy has gradually entered the public's field of vision and slowly entered daily life.

[0003] The popularity of hot spring therapy has led to a gradual increase in the amount of hot spring wastewater. The sulfide in the hot spring wastewater will have a greater inhibitory effect on the microorganisms in the biological treatment unit of the sewage treatment plant. In severe cases, it will cause the entire sewage treatment plant to be paralyzed, so it must be treated. Considering the seasonality of hot spring therapy and the small proportion of hot spring tailwater in the entire sewage treatment plant, from an economic point of view, it is not economically effective to treat it together with other domestic sewage in the sewage treatment plant. Comprehensive consideration requires that the hot spring tailwater be treated at the front end and in the pollution-producing links such as hot spring hotels and hot spring resorts. After treatment, it can be discharged into the city's inland rivers according to actual conditions, without having to enter the municipal pipe network for re-treatment. Summary of the invention

The water inlet pump on the submersible flow propeller will extract the hot spring tail water, and then the hot spring tail water is sent to the sedimentation unit. Then the stirring component will work, and flocculants will be added to the regulating unit at the same time. Then, under the action of the flocculant, the sediment will fall into the sedimentation unit. The filtered water will be sent to the vicinity of the guide tube, and then these hot spring tail waters will enter the oxygen control pool. The oxygen control pool cooperates to control the oxygen content, and then the treated hot spring tail water will be sent to the reaction pool. The MBR reactor can ensure the clarity of the effluent water. According to the comprehensive consideration of the water treatment volume, investment budget and floor area, the appropriate flat membrane or curtain membrane can be selected, and then the reacted hot spring tail water will be sent to the intermediate water pool.

Then the stirring motor will drive the stirring frame to rotate. The stirring blades will accelerate the combination of the flocculant and the hot spring tail water. Then the flocculated impurities will enter the sedimentation zone and enter the guide tube. After being extruded and formed by the guide tube, the flocculants can be fully deposited, so that the flocculant can play a full role. Then the flocculants enter the mud discharge component with the water for pressurization. Finally, the mud discharge component will discharge the flocculants from the sedimentation unit, and also reduce the mixing of some smaller flocculants into the subsequent processing operations, so as to improve the purification accuracy. The sedimentation component is waiting to discharge these impurities out of the equipment.

Taking into account the quantity, investment budget and floor space, a suitable flat membrane or curtain membrane is selected, and then the hot spring tail water after the reaction is sent to the intermediate water pool 16. The tail water is finally disinfected by the disinfection component 18, and the disinfection motor 1802 drives the moving gear 1803 to rotate. The moving gear 1803 moves under the restriction of the disinfection track 1801, and drives the disinfection rack 1804 to move, and at the same time drives the ultraviolet sterilizer 1805 to move. The ultraviolet sterilizer 1805 will disinfect the hot spring tail water and finally meet the discharge standards.
