About development of clearing constructions of the water drain in East Kazakhstan

On August, 8th, 2011 in Agency of Republic of Kazakhstan on affairs of construction and housing and communal services there has passed presentation of the project «Development of clearing constructions of the water drain of city of Ust- Kamenogorsk the East Kazakhstan».
The project is considered in RSE «Gosexpertiza».
Сustomer of the project: «Department of construction of the East Kazakhstan»
General designer: LLC «Vostokagropromproekt».
The existing maximal volume of sewage from industrial enterprises and city building makes 120 thousand m3/day. After realization of the project this parameter will increase up to 166 thousand m3/day.
The project provides reconstruction of mechanical, biological clearing and a sedimentary part of clearing constructions.
Necessity of development of the project is caused by an overload of clearing constructions where the technology of clearing of waters and processings of deposits is not to the full observed, therefore the necessary degree of sewage treatment before their release in the river Irtysh is not provided. Also recycling of deposits of silt collecting on platforms is not adjusted.
On left-bank clearing constructions of Ust-Kamenogorsk act not only city economic-household drains, but also dumps of the industrial enterprises. Therefore the maintenance in deposits of highly toxic metals in hundreds times exceeds their maximum-permissible norms that does not allow to use them as organic fertilizers.
Experts RSE «Gosexpertiza» to general designer and customer it is recommended to use as much as possible in the equipment design materials, products and the equipment of the Kazakhstan manufacturers.
