Description
Technical field
The present invention relates to technical field of sewage.
Background technology
At present, along with the raising of urbanization and living standards of the people, a large amount of dispersion type domestic wastewaters (as: samll cities and towns, at a high speedHigh road service area etc.), unprocessed or inappropriate processing is arbitrarily discharged and has been caused serious water environment pollution and ecological environment afterwardsWorsen. The actual conditions such as feature and the villages and small towns level of economic development of polluting in conjunction with decentralized, selection technique is simple, expense is cheap,Respond well water technology is the key that solves current pollution. Artificial swamp has little, the energy consumption of investment and operating cost is low,The advantage such as applied widely, has become the important technology of decentralized sewage pollution control.
But the artificial swamp in most of areas mainly, is generally deposited as main taking current wetland (horizontal drowned flow or vertical subsurface flow)In the poor problem of denitrification effect. Nitrated/denitrification process is as the main path of wetland Microbial denitrogenation, wherein nitrifying processBecome the limiting factor of denitrogenation. For the limited problem of nitrifying process, suitable artificial aeration can effectively promote nitrated carrying out.But continuous aeration cost is high, can not produce the required aerobic/anaerobic alternate environment of denitrogenation, and intermittent aerating can pass throughThe conversion of oxygen/anaerobic environment is strengthened the removal of nitrogen. For high strength waste water, intermittent aerating only can play nitrification.Meanwhile, denitrification process also needs to supplement enough carbon sources, is generally to regulate and control C/N ratio by additional carbon to realize efficientlyDenitrification process, but high cost.
