| titleOfInvention | Safe and efficient arsenic removal device for strong-acid wastewater integrated membrane |
| abstract | The utility model discloses a high-acid waste water integrated membrane safe and high-efficient arsenic removal device, the device include membrane contact hydrogen sulfide slow-release gas distribution unit, immersed membrane solid-liquid separation unit and membrane contact hydrogen sulfide degasification unit. The membrane contact hydrogen sulfide slow-release gas distribution unit is used for reacting with arsenic in the high-arsenic strong-acid wastewater to form arsenic sulfide precipitate by introducing hydrogen sulfide gas, so that arsenic elements in the wastewater are removed. The immersed membrane solid-liquid separation unit performs membrane filtration solid-liquid separation on the wastewater after reaction, and the arsenic sulfide precipitate after separation can be collected. And the membrane contact hydrogen sulfide degassing unit is used for carrying out hydrogen sulfide degassing treatment on the separated supernatant, and removing residual hydrogen sulfide in water through membrane absorption to form sodium sulfide so as to realize the recycling of sulfur elements. The utility model relates to an integrated membrane arsenic removal device has the technical characterstic such as product water quality is good, hydrogen sulfide high-usage, tail gas pollution is few, equipment is intensive, the running cost is lower, possesses good security and economic nature. |
