Embodiment 1

[0063] Waste tire recycling waste water treatment method comprises the following steps:

[0064] (1) Adding acid to the waste water to neutralize it to a pH of 6.8-7.2, and then performing multi-effect evaporation desalination treatment;

[0065] (2) adding a defoamer to the waste water in step (1), and then undergoing aeration and defoaming treatment for 3-6 hours, the defoamer accounts for 0.03% of the weight of the waste water;

[0066] (3) adding microbial water purifying agent in the waste water in step (2);

[0067] The parts by weight of the microbial water purifying agent are: 1.2 of the nitrifying bacteria powder, 0.9 of the denitrifying paracoccus powder, 0.6 of the sulfur bacteria powder, and 0.9 of the aniline degrading bacteria powder, whose weight accounts for 0.08% of the total weight of the waste water;

[0068] (4) add enzyme preparation in the waste water in step (3); The parts by weight of enzyme preparation are: pectinase 0.8, cellulase 0.9, dehydrogenase ...

Embodiment 2

Abstract

The invention belongs to the technical fields of environmental protection and water treatment, and concretely relates to a tire production enterprise wastewater treatment method. The tire production enterprise wastewater treatment method comprises the following steps: 1, adding an acid to wastewater in order to neutralize the wastewater to make the pH value reach 6.5-7.5, and carrying out multi-effect evaporation desalination treatment; 2, adding a defoaming agent to wastewater obtained in step 1, and carrying out aeration defoaming treatment; 3, adding a microbial water purifier to wastewater obtained in step 2; 4, adding an enzyme preparation to wastewater obtained in step 3; and 5, oxidizing and adsorbing wastewater obtained in step 4. The wastewater treatment method has the advantages of good water purification effect, fast water purification speed, high safety and no secondary pollution, and has a wide application range by using an adsorption material as a raw material and using microbes to carry out wastewater treatment, and water obtained through the method is extremely highly transparent and can be recycled.

Description

technical field [0001] The invention belongs to the technical field of environmental protection water treatment, and in particular relates to a method for treating waste water of a tire production enterprise. Background technique [0002] The amount of waste water in the tire factory is 0.0001 m of waste water per 30 kg of tires processed by acid etching 3 , The waste water contains acid 2.5g / L, iron chloride <5g / L, iron sulfate 5g / L, etc. The waste water needs to be neutralized and precipitated. Tire factories and rubber industrial product factories produce 0.001m of waste water for every 30kg of tires dipped 3 , each ton of products produces 40-45m of waste water 3 , The wastewater contains 0.1g / L of soap, 5g / L of calcium chloride, 10-30g / L of glue, etc. Generally, it needs to be treated by coagulation, sedimentation and filtration. [0003] The amount of waste water for cooling tires and products in each factory is: 0.2-0.3m per 30kg of tires 3 Wastewater, accordin...
