Abstract
The utility model discloses a recycling treatment system of a villiaumite-containing waste alkali solution. An infusion pump is used for conveying the villiaumite-containing waste alkali solution into a reaction kettle; an outlet of the reaction kettle is connected with a filter press; liquid at the bottom of the filter press enters a settling basin; filtering dreg at the upper part of the filter press enters a centrifugal machine to obtain a filtering solution which enters the settling basin; clean liquid in the settling basin is placed into a clean liquid storage groove by using a liquid level difference; and the clean liquid in the clean liquid storage groove is conveyed into an alkali solution circulating groove through a clean liquid pump to blend the concentration. Compared with the prior art, the recycling treatment system of the villiaumite-containing waste alkali solution realizes the recycling of the waste alkali solution, so that the pollution to an environment is avoided and also the 60% of the investment of raw materials and funds is saved.
