Description
Technical field
The utility model relates to a kind of Sewage treatment systems, relates in particular to the combinatorial artificial marsh sewage treatment system of samll cities and towns in a kind of being applicable to, belongs to technical field of sewage.
Background technology
Along with China's rapid economy development and Increase of population, quantity of wastewater effluent also constantly increases, particularly China villages and small towns, riverine basin and small city sanitary sewage uncontrollable discharge are to cause surface water body to pollute and one of important factor of eutrophication, also are the important and difficult tasks of of China's water pollution improvement.Along with the continuous expansion of cities and towns scale, the water consumption in cities and towns and water displacement have further aggravated the pollution of anxiety and the water quality of water all in continuous increase, and environmental problem becomes increasingly conspicuous, and the water crisis has become the important restraining factors of design economic law battle array.Therefore, solving the basic outlet that vast villages and small towns and small city water pollutes is low, the high efficiency sewage disposal technology of a kind of cost of development and Design.
Constructed wetland waste water treatment technology is a kind of ecological sewage purification technology with controllability and through engineering approaches characteristics that artificially designs and build by the simulating nature wetland that grows up the seventies in 20th century, by mixing and form bed of packings with soil and filler (as gravel etc.) in the depression that certain long-width ratio and the bottom surface gradient arranged artificially, make sewage mobile or mobile in the bed surface in the filler slit of bed body, and it is good to have performance in the plantation of bed surface, the surviving rate height, water resisting property is strong, growth cycle is long, waterplant (as reed, the stem or leaf of cattail etc.) attractive in appearance and economically valuable forms the animals and plants ecosystem of a uniqueness.The purification of sewage in artificial wet land system mainly worked in coordination with and finished by physics, chemical agent biological action with matrix, plant and microorganism, and different types of pollution is not had its main purification approach difference.The artificial swamp technology has that cost is low, easy care, advantage such as reliable for effect, provides a kind of feasible approach for solving the vast villages and small towns of China and small city water pollution problems.
The pollutent that artificial swamp is removed is in extensive range, comprises nitrogen, phosphorus, organism, trace element, pathogenic agent etc.Wherein, the removal of nitrogen is mainly finished by nitrated-denitrification of microorganism in the wetland bed body.Nitrifying process needs nitrifying bacteria community and necessary aerobic condition, and denitrification process needs denitrification flora, carbon source and stable anoxia condition.Traditional horizontal-flow wetland bed adopts from stream mode more, and the lower and reoxygenation ability of level of dissolved oxygen influences finishing of nitrifying process in the bed body; On the other hand, in the denitrification process of current wetland bed, lacking organic carbon source also becomes the principal element that influences denitrification process as the electronics the Worker's Stadium.In addition, the water (flow) direction of traditional drowned flow artificial wet land bed is single, and life-time service can make current unbalanced, and the water outlet end water surface is low, and medium lacks, thereby causes the wetland sewage treating efficiency to descend.
