Germany helps VN in waste treatment
VGP – Germany’s environmental scientists and experts s are cooperating and assisting Việt Nam to put into practice an interdisciplinary scientific research project from now until 2011. The project aims at finding out effective and sustainable solutions to control solid wastes and sewages in Việt Nam’s urban areas, especially Hà Nội.
Professor Peter Cornel, Project Director, stated that Hà Nội and many cities in Việt Nam lack sewage collection and treatment systems. In fact, only a small volume of sewage is treated in household underground filter-beds and then directly discharged into the environment. This has led to the high rate of ammonia in underground water, contaminating water resource, harming people’s health and seriously polluting the surface water.
According to experts, it is not very easy to replace old tanks with a newer collection system at a low price. Thus, the proper solution to this problem is to build a semi-concentrated system which can treat both mud in old filter-beds and sewage from new urban areas.
It is also necessary to upgrade the existing infrastructure works and integrate new waste management systems in a flexible way and appropriate to the rapid development of cities.
Mud from sewage system and filter-beds will be treated together with organic wastes. Biogas will be made use to fuel the treatment equipments.
