Abstract： |
The invention provides a method for restoring polluted water body of river, lake and reservoir as well as for controlling oxygen consume rate of polluted water body dissolving and water quality acidation. It is to do low-strength large quantity ultraviolet rays irradiating to water body to restrain life action of aerobic and facultative oxygen microbe in in to delay water body dissolving oxygen consume and accumulation of organic acid in metabolizing process, but to ensure them growing and metabolizing in lower rate to make water body keeping self-purification function, thus to increase pollutant load-bearing capacity of water body and delay water quality worsen. The ultraviolet irradiating equipment has flowability and can be operated in continuous type or batch-type. |
