Embodiment Construction

[0019] Such as figure 1 Shown, acid industrial wastewater treatment method of the present invention, it may further comprise the steps:

[0020] 1) carry out the contact oxidation treatment of blowing into air for 2-15 minutes with the acidic industrial waste water;

[0021] 2) adding a flocculant to the waste water obtained in step 1) for flocculation, then blowing in air for 2-10 minutes, and then performing a sedimentation treatment for 0.5-2 minutes;

[0022] 3) adding a bactericide to the waste water obtained in step 2) for sterilizing treatment, and blowing in air;

[0023] 4) After the waste water obtained in step 3) is filtered by a multimedia filtration process, the sedimentation treatment is carried out for more than 1 minute;

[0024] 5) After adding a reducing agent to the waste water obtained in step 4), use an activated carbon filtration process to perform filtration treatment, and then perform sedimentation treatment for more than 1 minute;

[0025] 6) After ...

Abstract

An acid industrial waste water disposal method and a system include the following steps: air is blown into the acid industrial waste water for 2 to 15 minutes as contact oxidation processing; a flocculating agent is added into the waste water for flocculation, and then air is blown again for 2 to 10 minutes, and then settlement is carried out for 0.5 to 2 minutes; bactericide is added into the obtained waste water for sterilization and air is blown into the water; the obtained waste water is filtered with multi-medium filtering process, and then the settlement is carried out for more than 1 minute; reducing agent is added into the disposed waste water and the water is filtered by active carbon and then settlement is carried out again for more than 1 minute; then the obtained waste water is filtered with a bag-filtering process, and then the water is filtered with a super-filtering process. The invention aims at providing the acid industrial waste water disposal method and the system which can economically and effectively dispose a large quantity of industrial emission acid waste water and is provide with better disposal effect.

Description

technical field [0001] The invention relates to a treatment method and system for acidic industrial wastewater. Background technique [0002] The outstanding characteristics of the sewage discharged by the chemical industry are acid, high turbidity, high mineral oil, high water hardness and high salt content. The existing industrial wastewater treatment methods and systems cannot economically and effectively treat a large amount of sewage discharged from the chemical industry. Contents of the invention [0003] The object of the present invention is to provide an acidic industrial wastewater treatment method and system capable of economically and effectively treating a large amount of acid sewage discharged from the chemical industry and having a good treatment effect. [0004] Acidic industrial wastewater treatment method of the present invention, comprises the following steps: [0005] 1) carry out the contact oxidation treatment of blowing into air for 2-15 minutes wi...
