Embodiment Construction
[0048] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0049] refer to Figure 1 to Figure 3 As shown, a kind of power plant desulfurization wastewater membrane concentration process disclosed by the present invention comprises the following steps:
[0050] 1. After the desulfurization wastewater is adjusted in the adjustment pool 1 to adjust the water volume and water quality, it will react with the lime with a mass concentration of 1.8-2.3% in the No. 1 reaction pool 21 and continuously stir for 10-20 minutes, and then enter the No. 2 reaction pool 21 in the state of coagulation liquid and mix with it. The soda ash with a mass concentration of 2.0-2.5% is continuously stirred and reacted for 10-20min, and then enters the concentrated water tank 3 in the state of coagulated liquid, and the coagulated liquid is continuously stirred, and the mass concentration of the coagulated liquid in the conce...
