ecological problems of gorgan bay in the southeast corner of the caspian sea (iran) and ways of improvement

Letter to editor: introduction: the use of antiseptics and disinfectants in daily health protocols has a consequence of changing the quality of wastewater to be toxic to microbes. as a result, microbiological wastewater treatment has the potential to not be processed properly. to solve the problem of disinfectant-rich wastewater, a plant-based treatment method can be useful, the implementation of which is a land treatment system for wastewater.materials and methods: the data collection method was carried out through the mendeley reference manager, searching for articles online, and placing the terms land treatment system, and disinfectant-rich wastewater. the selected articles were uptodate and had a significant relationship between the two terms.results: this sanitation system can be a stretch of land and/or a pond of water, on which plants can grow and process. normal concentrations of disinfectants for microbial elimination had no negative effects on the growth of various types of plants. plants continue to live in the stress of water rich in disinfectants, as a condition of their ability to treat wastewater. the involvement of various wastewater treatment media makes evapotranspiration dry bed and evapotranspiration wet bed or wetland ponds capable of processing various pollutants. this approach can be implemented for onsite and offsite sanitation system.conclusion: in this context, under conditions of enrichment of disinfectants in wastewater during the covid19 era, the land treatment system becomes feasible to solve the problem of changing the quality of wastewater.
