"Three wastes" generally refer toIndustrial pollution sourcesWaste water, waste gas andsolid waste 。China has become a major tanning country in the world, with increasing wastewater, waste residue and waste gas.If leather waste is not treated, it will endanger the life and health of animals, plants and human beings.Especially in the three wastes of tanningChromium pollution、Sulfur pollution, salt pollution, etc. are fatal to the leather industryPollution sourceAlthough there are better pollution control systems, there are still some problems in these systems, such as incomplete pollution controlSecondary pollutionEtc.Therefore, we must attach great importance to it. We must use high-tech means to comprehensively treat and recycle the three wastes, purify the living environment, and protectecological equilibrium。[1]
Waste gas, waste watersolid waste The general name of.It can also be called "raw materials in the wrong place".Recycling it can also improve environmental health.
The "three wastes" shall be treated and disposed by multi-level purification, decontamination, compression and volume reduction, incineration, solidification and other measures according to different situations.This process is called "three wastes" treatment and disposal.
