Description
Technical field
The utility model relates to wastewater treatment equipment, relates in particular to a kind of landscape ecological type decentralized type sewage treatment unit.
Background technology
Be accompanied by fast development and the growth in the living standard of economic society, people have had higher requirement to the comfort level of living environment, sewage work moves as sewage treatment facility, require also more and more highlyer, improvement is needed in the impact that sewage treatment facility causes surrounding enviroment badly.China's water pollution and shortage of water resources problem are day by day serious, and wastewater treatment efficiency is also had higher requirement.But, due to the raising of town sewage processing emission standard, being subject to the bottleneck effect of traditional activated sludge process technique, denitrogenation dephosphorizing efficiency cannot further improve, and traditional activated sludge process cannot meet emission standard, needs badly and carries out efficient novel process research.In addition, stable state is to ensure stable effluent quality the prerequisite lower than certain standard, existing most of sewage work is faced with processing power and promotes and upgrading pressure, under the condition of Land Resource Reserve deficiency, be badly in need of the treatment technology of efficient stable, not only meet the objective condition that floor space is little, also need to ensure even advanced treatment and the reuse of stably reaching standard of water outlet.Therefore " leisure landscape style " sewage treatment process of, develop a kind of stable, efficient, short distance, realizing the unification of sewage disposal and landscape ecological construction becomes sewage disposal technology personnel's the objective of the struggle.
It is long-standing that plant participates in sewage treatment process, uses Wastewater Treatment by Constructed Wetlands can trace back to 1903, build Britain Yorkshire Earby in, is considered in the world first for the treatment of the artificial swamp of sewage, and operation is until 1992 continuously.And Constructed Wetland Ecology System comes into one's own gradually all over the world and is used, or after proposing root district method (the root-zone-method) theory, 20 century 70 German scholar Kichunth start, root district law theory is emphasized the effect of higher plant in marsh sewage treatment system, first be that they can be the heterotrophic microorganism supply oxygen of its rhizosphere, thereby in reductibility matrix, create a kind of microenvironment of oxygen enrichment, microorganism grows on the root system of waterplant, they have just set up symbiosis cooperative relationship with higher plant, increase the degradation speed of Pollutants in Wastewater, be oxygen and the anaerobic environment of holding concurrently in the place away from root district, be conducive to hold concurrently oxygen and anaerobism cleaning action, on the other hand, the growth of waterplant root is conducive to improve the hydraulic conductivity energy of bed substrate layer.Therefore, plant is combined with advanced sewage treatment process efficiently, not only can improve sewage treating efficiency, can also realize the unification of sewage disposal and landscape ecological construction.
SBR(sequencing batch reactor activated sludge process, sequencing batch active sludge) system is the sewage treatment process system of widespread use always.First, this reactor flexible operation is succinct.It can coordinate different influent quality adjust operation patterns.In the second, SBR fluidised form, belong to completely and mix, and aspect organic matter degradation, be plug-flow on the time.Therefore only need adjust the reaction times in order to reach compared with high clearance.Greatly reduce like this occupation of land, be particularly suitable for middle-size and small-size water factory.The 3rd, the precipitate phase of SBR effectively separates muddy water, and water outlet concentration of suspension is low, without separately establishing settling pond.The 4th, in SBR technique, without second pond and returned sluge system, a lot of situations also can not established preliminary sedimentation tank, thereby capital cost is low, take up an area few.
SBR technique is substantially perfect through near further investigation and development, but still exists some unsatisfactory places.First, intermittent water inflow makes treatment process lack continuity.If water treatment is moved continuously, need to establish many cell systems, increase initial cost.Secondly, need for the organic waste water of some high-concentration hardly-degradables the reaction times of growing.Again, SBR technological operation operation is comparatively complicated, must adopt automatically and control, and affiliated facility is more.In addition, because this process pool body mostly is open type, the impact on surrounding environment in operational process is larger, especially when its foul smell problem that this technique produces during as scattering sewage treatment facility operation limits one of subject matter of its widespread use especially.Therefore, optimize this technical process, realizing efficient, stable sewage treatment process becomes the focus that researchist pays close attention to.
If traditional SBR technique can be combined with landscape plant, optimization technological process, the array mode of a suitable plant and sewage treatment process is proposed, can overcome the shortcoming of traditional activated sludge process, realize the mutual supplement with each other's advantages of traditional activated sludge process and landscape plant, obtain " leisure landscape style " sewage treatment technique of efficient, stable, short distance, less energy-consumption.
