Sewage pretreatment equipment for electronic-grade dimethyl carbonate production

The invention discloses sewage pretreatment equipment for electronic-grade dimethyl carbonate production, and relates to the technical field of sewage treatment. The gravity effect is fully utilized to drive discharged sewage to rotate in the pretreatment tank, solid substances in the sewage are separated out, and the subsequent sewage treatment efficiency is improved; the closed-loop neutralization regulation process for the pH value of the sewage is adopted, the dosing amount can be regulated in real time, and the sewage can be driven to be fully mixed with a medicament while dosing is carried out, so that the efficiency of the neutralization regulation procedure of pretreatment is higher; and the screened solid substances can be automatically collected into the waste collection pool, manual regular cleaning of the pretreatment pool is not needed, and the maintenance cost of overall sewage treatment is reduced. 本发明公开了一种电子级碳酸二甲酯生产用污水预处理设备，涉及污水处理技术领域。本发明充分利用重力的作用，驱使排入的污水在预处理池中旋转，将污水中的固体物质分离出去，提升后续污水处理的效率；采用闭环
