Phosphorus removal cycle in wastewater treatment process – a Mongolian perspective


Монгол улсад үйл ажиллагаа явуулж буй бохир ус цэвэрлэх байгууламжуудын хүчин чадлыг нэмэгдүүлэх, шинээр цэвэрлэх байгууламж барих ажил чухал шаардлагатай байгаа бол хамгийн чухал зүйл нь цэвэрлэгээний технологийн шинэчлэл юм. Та бүхэнд Швед улсын Амьдралын шинжлэх ухааны их сургуулийн "Swedish university of life science" мастер оюутны эрдэм шинжилгээний өгүүллийг хүргэж байна.

Introduction
Phosphorus is an essential element in the world. The symbol for phosphorus is P. It is a nonmetallic chemical element and atomic number 15. The name of phosphorus name given from Greek mythology Φωσφόρος which it means light bearer also in Latin ”lucifer”. Phosphorus removal in wastewater treatment is crucial because  high nutrients concentration leads to eutrophication and reserves of phosphorus are decreasing. Modern developed countries have developed phosphorus removal strategy used in wastewater treatment plants. Mongolia also understand concept of removing phosphorus from wastewater is important to prevent future environmental changes and try to follow developed countries. The only Mongolian wastewater treatment plant was built in 1964. Until today, Mongolian wastewater treatment plant operates only in basic level removing from organic pollutants. The treatments need to be improved because of downstream pollution. This paper aims explore which method of phosphorus removal is more suitable for Mongolian environmental conditions.
