Description
Technical field
The invention belongs to sewage treatment area, relate to a kind of process polluted river, the combination of purification municipal wastewater artificial swamp Structure and energy.
Background technology
Matrix-plant-microbial ecosystem that the class that artificial wet land system is made up of matrix, waterplant and microorganism is special is the sewage disposal technology of the strengthened purification ability of artificial construction and controlling run.Micropopulation based on bacterium is dropped in Constructed Wetland Ecology System and plays critical effect.Exist all in a large number in waste water, on waterplant root system or filler as microorganisms such as bacterium, fungi and actinomycetes, artificial swamp is that their existence and breeding provide stable environment.
Utilize Artificial Wetland Techniques purifying contaminated river, have very large effect to structure aquatic ecosystem, China also has some successfully to apply in recent years in this respect.It is relatively good that artificial swamp has 1. Nitrogen/Phosphorus Removal to dirty water purification; 2. invest low, good in economic efficiency, run control relatively simple; 3. certain capacity of resisting impact load is had to water quality, the water yield; The advantages such as 4. ecological environment benefit is remarkable, be implanted with plant owing to planting, its landscape effect is also better simultaneously.Artificial swamp follows the principle of landscape ecology in river regulation, makes river regulation vegetalization and life, and its outstanding advantages is that river ecosystem is restored, and the self-purification capacity of water body strengthens, and the species diversity in basin also increases accordingly.These all match with the target of building ecocity, add city inland river water resources anxiety in recent years, and artificial swamp can realize the resource utilization reuse of river, therefore has wide development space to process city river sewage.
But, pass through for many years to research trial and the practice of Wastewater Treatment by Constructed Wetlands both at home and abroad, find that it is in operation and also there is a series of problem, attract mosquitos and flies as stench greatly, easily appears in floor space, be subject to the problems such as temperature impact, easily blocking, these problems need to solve further, especially the blockage problem of artificial swamp, blocking is often because water inlet TSS is too high and plant decay causes nondegradable suspended substance to accumulate in matrix, thus reduce the hydraulic conductivity of wetland, finally cause blocking.Therefore acidication cell system is added the front portion of artificial swamp, to suspension particulate matter, there is good removal effect as strenuous primary treatment, effectively can solve the long playing blockage problem of wetland.
The application of acidication comparatively early, but is with the form of simple hydrolysis acidification pool mostly, and people do not give enough attention to the preconditioning technique of this simple economy.Along with the increasing of sewage disposal difficulty, the raising of processing requirements and country are to the call of energy-saving and emission-reduction, the advantage of acidication technology displays gradually.But hydrolysis acidification pool is as independent art breading sewage, except having good removal effect to suspension particulate matter and BOD, it is limited to degradation effects such as COD, nitrogen, phosphorus, and the water conservancy residence time is longer.For optimizing its treatment effect, hydrolysis acidification pool is generally applied as the strenuous primary treatment of other techniques.
