Abstract

The invention belongs to the technical field of environmental-protection water treatment, and particularly relates to a method for treating wastewater produced in waste tire recycling. The method for treating the wastewater produced in the waste tire recycling includes the following steps: (1) adding an acid into the wastewater, neutralizing to the pH of 6.5-7.5, and then carrying out multi-effect evaporation desalination treatment; (2) adding a defoaming agent into the wastewater in the step (1), and then carrying out aeration defoaming treatment; (3) adding a microbial water purifying agent into the wastewater in the step (2); (4) adding an enzyme preparation into the wastewater in the step (3); and (5) oxidizing and adsorbing the wastewater in the step (4). The wastewater treatment method is good in water purification effect, fast in water purification speed, high in safety and wide in usable range, has no secondary pollution, and treats the wastewater with a material having the adsorption capacity as raw material and with supplement of microorganisms; and the treated water has extremely high transparency, 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 generated in the recycling of waste tires. Background technique [0002] With the development of transportation, the number of various types of vehicles has increased sharply, and not only traffic jams and exhaust pollution have followed, but also how to deal with a large number of waste tires produced each year has become an urgent problem to be solved. If a large number of waste tires are stacked randomly, it will not only affect the landscape, but also breed mosquitoes and germs due to accumulated water, thereby causing serious pollution to the environment. In addition, a large number of waste tires piled up is still a hidden danger of major fires. How to recycle and comprehensively utilize tires to achieve the purpose of avoiding environmental pollution and reusing resources has become a concern o...
