[0020] In order to make the content of the present invention easier to be understood clearly, the following further describes the present invention in detail based on specific embodiments in conjunction with the accompanying drawings.
[0021] Such as Figure 1~3 As shown, a comprehensive treatment process for desulfurization wastewater, the process steps are as follows:
[0022] 1) Wastewater collection and buffering: the incoming desulfurization wastewater enters the desulfurization wastewater raw water tank 1, and the raw water tank agitator 2 is installed in the raw water tank to prevent precipitation;
[0023] 2) Chemical lime treatment: The wastewater is lifted by the wastewater lifting pump 3, and the wastewater enters the neutralization tank 4 from the original water tank 1, and the neutralization tank 4 is added with a mass concentration of 5%-10% Ca(OH) 2 Solution, set the online PH meter, the PH value in the control box is 9.2-9.8, mainly to remove SO 4 2- ,heavy metal ion;...
