Inhibition Effects of Full Degradation Barley Straws on Algal

摘要

How to control water eutrophication bloom having been the difficulties in the field of environmental engineering. Various measures have been taken to control the occurrence of algal blooms and slow down the outbreak of the frequency, such as source control (non-point source pollution control and abatement nutrient loading, sediment dredging, etc.), inhibition algaecide measures (artificial salvage or kill algae, etc.) have failed to achieve the desired effect, which had the effect only in the short term, even some improper physical or chemical methods had exacerbated the fragile wetland ecosystem. Therefore, to explore effective, economical, and no secondary pollution, low ecological risk control algal blooms method is an important task for environmental science. In this paper, barley straws with pretreated (nitrogen and phosphorus) were added to the eutrophication water bodies, to analyze the inhibition effect of full degradation barley straws on algal. We prepared a number of 50×20×25 cm glass tanks and aerators, and selected mature dry barley straw as the test material. Barley straws were cut into 0.5g/m3>0.3g/m3>0.1g/m3, when the concentration of degradation of barley straw when 0.1g/m3 basic loss of algal function, show that the degradation of barley straw algal role of broad-spectrum resistance.
