प्रश्न
Suggest suitable mechanism(s) for waste management in fertilizer industries.
उत्तर
Suitable mechanisms for waste management in fertilizer industries:
Fertilizer industries generate solid waste, wastewater (contains organics, nitrates, alcohols, ammonia, phosphorous, heavy metals such as cadmium and suspended solids) and air pollutants (particulate matter, gaseous NH3, oxides of nitrogen, sulphur and carbon dioxide). So, the waste management mechanisms in fertilizer industries are:
- Wastewater should be treated before its discharge into the surrounding water.
- Solid waste should be dumped in a safe place by following safety measures.
- Air pollution should be controlled e.g., by fitting certain adsorption equipment in chimneys to absorb harmful pollutants before the smoke is released into the atmosphere.
