| titleOfInvention | Desulfurization wastewater softening pretreatment equipment and its treatment method |
| abstract | The invention relates to a desulfurization wastewater softening pretreatment device and a treatment method thereof, comprising a primary reaction tank, the discharge port of the primary reaction tank is connected with the first feed port of a dehydration device, and the discharge port of the dehydration device is connected with two A first-stage reaction tank, the outlet of the second-stage reaction tank is connected with a filter device, and the outlet of the filter device is connected with a sludge transmission pipeline, the sludge transmission pipeline includes a first pipeline and a second pipeline, the first pipeline is connected to the desulfurization device, The second pipeline is connected to the second material inlet of the dehydration device, and is connected to the desulfurization device to be provided with an independent discharge port, and a detection device is installed on the discharge port. Therefore, the calcium carbonate precipitate generated in the secondary reaction tank can be directly reused in the desulfurization system, which is not easy to foul the tubular membrane and ceramic membrane, prolongs the cleaning cycle and reduces operating costs. Most of the dissolved silicon is precipitated in the primary reaction tank. After the solid-liquid separation by the dehydrator, there will be no precipitation of sodium carbonate in the secondary reaction tank. |
