Abstract
The scientifically proved practical solution is developed for the issue of dust emission reduction from the dust-forming surfaces of the industrial facilities. The solution is achieved through simple inexpensive technologies which provide quick and effective dust protection and cause the least harm to further processing of the raw materials. The offered method allows to green the dust-forming surface during one growing season, provides stability and independent spreading of the formed phytocenosis on additional areas within further seasons. The developed method consists in the following. Dried decontaminated sludge from treatment plants of aeration stations is offered as a basis for the phytocenoses development and in fact is a basis for the artificial soil. The sludge containing large amounts of nutrients, when applied to the surfaces, significantly improves agrophysical properties of the artificial soils. The use of the sludge is available only if its chemical and bacteriological safety are approved by certified and accredited laboratories. The practical part of the method consists in a mechanized application of the substrate in a form of dried settled decontaminated sludge from the treatment plants of the local aeration stations to the dust-forming surfaces. The layer thickness should be no less than 10-15 cm. In autumn period Salsola iberica seeding in the substrate layer is performed. Salsola iberica was selected for several reasons. The plant is a well represented local weed and it is not a quarantine plant. Salsola is also known as a dominant plant which colonize dry and exhausted soil. Therefore, Salsola iberica plant communities are very suitable due to developing a quite resistant vegetation cover on the tailings areas. As a result (ecological effect), the application of the accelerated recultivation to dust-forming surfaces leads to almost complete dust removal throughout the vegetation period (from May till October). The important aspect is that the formed vegetation cover is able to reproduce itself in further growing seasons. Разработан способ ускоренного озеленения пылящих поверхностей техногенных объектов. В качестве основы субстрата для создания фитоценозов предлагается использование сухих обеззараженных иловых осадков очистных сооружений станций аэрации. Предлагаемый способ пылезащиты позволяет добиться озеленения пылеобразующей поверхности в течение всего одного вегетационного сезона, обеспечивая устойчивость и распространение сформированного фитоценоза на дополнительные площади без помощи человека на протяжении последующих сезонов. Сформированный растительный покров способен многократно самовоспроизводиться на протяжении последующих временных сезонов без дополнительного вмешательства.
