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.

Phosphorus removal cycle in wastewater
treatment process – a Mongolian perspective

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.
