Embodiment 1

[0051] The waste tire recycling wastewater treatment process includes the following steps:

[0052] (1) Add acid to the wastewater to neutralize its pH to 6.9-7.2;

[0053] (2) Add defoamer to the wastewater in step (1), and then undergo aeration and defoaming treatment for 3 hours. The defoamer accounts for 0.12% of the body weight of the wastewater;

[0054] (3) Add flocculating water purifying agent to the wastewater in step (2), polyaluminum chloride 16, polyacrylamide 12, ferrous sulfate 8, aluminum sulfate 10; flocculating water purifying agent accounts for 0.08% of the total weight of wastewater ; Then add the microbial water purifier, the added amount accounts for 0.1% of the total weight of the wastewater;

[0055] The weight parts of the microbial water purifying agent are: nitrifying bacteria powder 1.2, denitrifying paracoccus powder 0.9, sulfur bacteria powder 0.6, aniline degrading bacteria powder 0.8, and flocculating bacteria powder 0.9;

[0056] (4) Add enzyme preparat...

[0067] (2) Add a defoamer to the waste water in step (1), and then undergo aeration and defoaming treatment for 5 hours. The defoamer accounts for 0.05% of the weight of the waste water;

[0068] (3) Add flocculating water purifying agent to the wastewater in step (2), polyaluminum chloride 4, polyacrylamide 4, ferrous sulfate 2, aluminum sulfate 3; flocculating water purifying agent accounts for 0.01% of the total weight of wastewater ; Then add microbial water purifier;

[0069] The weight parts of the microbial water purifying agent are: nitrifying bacteria powder 0.5, denitrifying paracoccus powder 0.4, Pseudomonas aeruginosa powder 0.2, Candida lipolytica powder 0.2, Bacillus megaterium 0.2, which The added amount accounts for 0.02% of the total weight of wastewater;

[0070] (4) Add enzyme preparation to the wastewa...

Embodiment 3

[0073] The waste tire recycling wastewater treatment process includes the following steps:

[0074] (1) Add acid to the wastewater to neutralize its pH to 7.2;

[0075] (2) Add a defoamer to the wastewater in step (1), and then undergo aeration defoaming treatment for 6 hours. The defoamer accounts for 0.3% of the weight of the wastewater;

[0076] (3) Add flocculating water purifying agent to the wastewater in step (2), polyaluminum chloride 16, polyacrylamide 16, ferrous sulfate 12, aluminum sulfate 16; flocculating water purifying agent accounts for 0.3% of the total weight of wastewater ; Then add the microbial water purifier, the added amount accounts for 0.3% of the total weight of the wastewater;

[0077] The weight parts of the microbial water purifying agent are: nitrifying bacteria powder 2.0, denitrifying paracoccus powder 1.5, Pseudomonas aeruginosa powder 1.2, Candida lipolytica powder 0.8, Bacillus megaterium 0.8;

Abstract

The invention belongs to the technical field of environment-friendly water treatment and particularly relates to a treatment process for wastewater generated during recycling process of a waste tire. The treatment process comprises the following steps: (1) adding acid into waste water for neutralization until the pH is 6.5-7.5; (2) adding an antifoaming agent into the waste water in the step (1), and performing antifoaming treatment for 3-6 hours by aeration; (3) adding a microorganism water purifying agent into the waste water in the step (2); (4) adding an enzyme preparation into the waste water in the step (3); and (5) feeding a water body in the step (4) into a sedimentation tank for filtration. By the adoption of a sewage treatment process, the water purification effect is good, the water purification speed is high, the safety is high, and secondary pollution is not caused; materials with adsorption capacity serve as raw materials, and microorganisms serve as auxiliary materials to treat sewage, so that the using range is wide, and treated water is extremely high in transparency and is recyclable.

Description

Technical field [0001] The invention belongs to the technical field of environmental water treatment, and specifically relates to a waste tire recycling wastewater treatment process. Background technique [0002] With the increasing development of transportation, the number of various types of cars has increased sharply. Not only are traffic jams and exhaust pollution problems followed, how to deal with the large amount of waste tires produced every year has also become an urgent problem that people face. A large amount of waste tires, if stacked arbitrarily, will not only affect the landscape, but also breed mosquitoes and bacteria due to stagnant water, which will cause serious environmental pollution. In addition, a large number of waste tires are still a hidden danger of major fires. How to recycle and comprehensively use tires in order to achieve the goal of avoiding environmental pollution and reusing resources has become a concern for experts in the industry. At present,...
