3results about How to "High fluoride removal efficiency" patented technology

The application provides a system treatment process for fluorine-containing wastewater, which comprises the following steps: a fluorine-containing wastewater treatment process, a sludge treatment process, a defluorination filter material regeneration process and a sludge waste liquid treatment process. The system treatment process for fluorine-containing wastewater has the advantages of low sludge yield, low flocculant consumption, low treatment cost, high adsorption capacity, greatly prolonged adsorption time of the adsorbent, reduced regeneration frequency, no discharge of regeneration liquid, and effectively solved problem of difficult treatment of by-products of traditional treatment processes.

The present application relates to the technical field of wastewater treatment, and discloses a deep fluorine removal integrated system for fluorine-containing mine water, which comprises: a raw water supply device for conveying raw water to a fluorine removal device; a medicament supply device for conveying medicament to the fluorine removal device; a bubble supply device for generating micro-nano bubbles; a slag scraping device arranged at the top of the rear end of the fluorine removal device, which is used for scraping off impurities on the upper part of wastewater in the fluorine removal device; a clean water pool in communication with the fluorine removal device; a detection module arranged in the clean water pool and raw water respectively, which is used for monitoring the water quality of clean water and raw water; and a control module electrically connected with the raw water supply device, the medicament supply device, the bubble supply device, the slag scraping device and the detection module. The present application not only improves the fluorine removal efficiency and water quality, but also realizes automatic operation through intelligent control, greatly reducing the complexity and cost of manual operation.

This invention discloses a combined treatment tank and process for fluoride-containing wastewater, belonging to the field of fluoride-containing wastewater treatment technology. The invention includes a homogenization tank, a high-efficiency inclined plate sedimentation unit, a sludge conditioning tank, and an online influent monitoring chamber. The high-efficiency inclined plate sedimentation unit includes a distribution tank, a mixing tank, a flocculation tank, a sedimentation zone, a sludge zone, a clear water zone, and an effluent channel. This invention uses a combined treatment tank integrating the homogenization tank, the online influent monitoring chamber, the high-efficiency inclined plate sedimentation unit, and the sludge conditioning tank to treat fluoride-containing wastewater. This allows for the combination of various irregular processes into a more regular-looking tank shape, shortening the construction length of sewage pipe networks, improving treatment efficiency, reducing land occupation, and reducing construction and transportation costs. The distribution tank helps balance the influent volume of the treatment system, homogenizes the water quality of the fluoride-containing wastewater, makes the water distribution more uniform, and enables subsequent treatment units to operate stably, improving treatment stability and defluorination efficiency.
