Description
Technical field
This utility model relates to a kind of sewage treatment plant tail water advanced treatment system, belongs to technical field of sewage.
Background technology
In order to improve the quality of water environment of receiving water body so that it is reaching the standard of reuse water quality, usual urban wastewater treatment firm secondary effluent must carry out advanced treating, and the main object of its removal is the pollutant such as nitrogen, phosphorus and low-concentration organic. How sewage treatment plant tail water is carried out advanced treating, alleviate water pollution load further, be a problem in the urgent need to address.
Existing further treatment technique based on traditional methods such as coagulant sedimentation, membrane Bio-reactor Technology, BAF, biological contact oxidation process, biofiltration, activated carbon adsorption, micro-filtration membrane or reverse osmosiss, the shortcomings such as these methods all exist that investment is high, energy consumption high, be likely to produce secondary pollution and treatment effect is limited.
Along with the continuous expansion of the research field of China's advanced treatment of wastewater and scope, have also been developed some with the monotechnicss such as artificial swamp be core biologic technology and combination technique. Existing Artificial Wetland Techniques has the features such as small investment, operating cost is low, has become as the important technical of sewage treatment plant tail water advanced treating. Therefore the advanced treatment system being core with artificial swamp, can not only carry out advanced treating to tail water, makes tail water resource recycle, moreover it is possible to local environment is made moderate progress, and takes into account Wetland Education and the function of Wetland ecological view leisure simultaneously.
Summary of the invention
The purpose of this utility model is in that: overcome the defect of above-mentioned prior art, it is proposed to a kind of cost is less, the system of deeply treating wastewater treatment plant tail water that substantially do not produce secondary pollution and can improve the ecological environment.
In order to solve above-mentioned technical problem, the technical scheme that the present invention proposes is: a kind of sewage treatment plant tail water advanced treatment system, including the facultative lagoon set gradually along water (flow) direction, first-surface artificial wetland, ecological pond and secondary surface artificial wetland; Being connected by the first ecology corridor between described facultative lagoon with first-surface artificial wetland, connected by canal for water conveyance between described first-surface artificial wetland and ecological pond, described ecological pond is followed by secondary surface artificial wetland; Substrate in described one-level, secondary surface artificial wetland is divided into three layers, is followed successively by the coarse sands layer of the boulder bed of particle diameter 50-100mm, the gravel layer of particle diameter 15-30mm, particle diameter 1-5mm from the bottom up; Described one-level, secondary surface artificial wetland inwall and substrate between be equipped with impervious barrier; Described one-level, secondary surface artificial wetland are all planted and are implanted with emergent aquactic plant, plant and be implanted with submerged plant, emergent aquactic plant and floatingleaved plant in described ecological pond, plant and be implanted with emergent aquactic plant and hygrophyte in described first ecology corridor.
Facultative lagoon is most widely used a kind of stabilization pond, there are three regions: 1 in facultative lagoon) aerobic zone, top layer, aerobic bacteria and algae symbiosis, there is the feature of aerobic ponds; 2) bottom anaerobic zone, the solid impurity being accumulated in this region is fully decomposed by anaerobe; 3) middle part facultative district, i.e. transition region between aerobic zone and anaerobic zone, also exists the amphimicrobe that can play two kinds of effects, and by amphimicrobe decomposing organic matter.
The tail water of sewage treatment plant in use, is first introduced facultative lagoon through pipeline by this utility model, and tail water is carried out preliminary treatment; Then the water outlet of described facultative lagoon introduces first-surface artificial wetland through the first ecology corridor, ecological pond is introduced by first-surface artificial wetland after being further processed, water outlet purifies and builds graceful view further, the water outlet of last ecological pond enters secondary surface artificial wetland, discharges to natural water after tail water process is up to standard.
This utility model is by the tail water of the group technology process sewage treatment plant of facultative lagoon+artificial swamp (i.e. one-level, secondary surface artificial wetland)+ecological pond, not only high treating effect, secondary pollution are little, and overcome the shortcoming that traditional treatment method cost is high, its investment, maintenance and operating cost are low, it is especially suitable for the rural area that population density is relatively small, operating cost is low, management simplicity, particularly artificial wet land system substantially adopts the mode of flow by gravity, basic Non-energy-consumption in processing procedure. Further, described facultative lagoon, artificial swamp, ecological pond and connect described facultative lagoon and be respectively provided with different water plants from the first ecology corridor of first-surface artificial wetland, it is possible to while processing tail water, build graceful natural landscape.
Improving further of technique scheme is: be provided with the water-retention pool before described facultative lagoon, the described water-retention pool is connected by the second ecology corridor with facultative lagoon, it is equiped with floating fountain type aeration machine in the described water-retention pool, also plants in described second ecology corridor and be implanted with emergent aquactic plant and hygrophyte. So, sewage treatment plant tail water is first introduced through pipeline and carries out in the water-retention pool being all re-introduced into the water-retention pool with after adjustment process, its water yield and water quality so can be made all to remain stable for, provide an operating condition that is stable and that optimize for follow-up water treatment system, it is ensured that water-retention pool normal operation. Described floating fountain type aeration machine can build fountain view while aeration, improves sight. It addition, water-retention pool aeration can increase dissolved oxygen, thus there is aerobic reaction, Organic substance can be degraded.
Improving further of technique scheme is: described antiseepage film is by layer of plastic film and the non-woven fabric compounded composite geo-membrane being positioned at described plastic sheeting both sides. Non-woven fabrics is a kind of macromolecular fibre chemical material; there is higher tensile strength and extensibility; after being combined with plastic sheeting; not only increase tensile strength and the puncture resistant ability of plastic sheeting; and owing to nonwoven surface is coarse; increase the coefficient of friction of contact surface, be conducive to stablizing of composite geo-membrane and protective layer. Meanwhile, antibacterial and chemical action are had good erosion resisting by them, have good effect in acid, the erosion of alkali, salt, it is possible to prevent from oozing the pollution to subsoil water under sewage.
