The tailwater is discharged into the Yangtze River through the Beihu gate.Food grade, capacitor gradeThe sewage treatment station has a treatment scale of 300m.Ten thousand tons of crystalline phosphoric acid salt production devices.The treatment process is:"Secondary pretreatment + secondary coagulation flotation treatment + neutralization filtration treatment"Food grade, capacitor grade2.Ten thousand tons of crystalline phosphoric acid salt production devices.And passed acceptance.Exhaust gas:0.8Industrial phosphoric acid device: After the reaction of the hydration tower, PO

After being separated by the separation tower (the upper part is a mesh demister, the middle part is an acid spray head, and the lower part is a cyclone separator), it is de-misted and then passed through the water washing tower.如下：

1、废水：含磷废水经生产污水管道收集至废水槽后泵入厂区内污水处理站处理后部分回用（回用率约为30%），未回用的含磷废水汇同其他生产废水、初期雨水一并经调节池混合均匀后与厂区生活污水一并经架空专用管道排入武汉化学工业区污水处理厂进一步处理，尾水经北湖闸排入长江。

污水处理站处理规模为300m3/d，处理工艺为“二级预处理+二级絮凝气浮处理+中和过滤处理”2. Basic situation of the existing plant area
