Description
Technical Field
The utility model belongs to the municipal works field, concretely relates to device that rainwater and assisted energy ripples treatment quality of water are collected in sponge city.
Background
Along with the acceleration of urbanization process, impervious ground area increases gradually, not only can increase the pile up of rainwater runoff, especially forms the waterlogging easily in the torrential rain season, and the rainwater runoff can receive the pollution because of reasons such as discharging smoothly moreover, can cause bigger influence after the contaminated water enters into natural water. In addition, the repeated utilization rate of rainwater can be reduced by the area of the impervious ground, most of rainfall is directly discharged through a drainage system, the rainwater is not well utilized, the drainage-based urban rainwater discharge mode is gradually not suitable for the situation of water resource shortage in China at present, under the common influence of the factors, the sponge urban concept is provided, the accumulation, permeation and purification of rainwater are realized, the repeated utilization rate of the rainwater is improved, the ecological environment is protected, the phenomenon of water resource shortage is solved, and the harmonious hydrological ecological environment is further established.
The establishment of sponge cities must be supported by a perfect planning idea. Generally speaking, the planning idea of rainwater utilization in sponge cities is a brand-new rainwater utilization and removal mode, the brand-new utilization and removal mode can effectively avoid the problems in the traditional rainwater utilization and removal mode, and the current situation of water resource shortage is effectively relieved on the basis of improving the rainwater utilization rate. Meanwhile, if the planning of rainwater utilization of the sponge city is to be realized, related departments, especially water conservancy departments, are required to abandon the traditional rainwater utilization and discharge idea in the process of regional rainwater discharge work, and a brand-new rainwater utilization and discharge idea is established, so that the aim of ecological protection can be further realized on the basis, a novel rainwater management mode is realized, and finally, reasonable utilization of rainwater resources can be realized and the effect of resource saving is achieved.
The rainwater collection is actually a rainwater collection system which collects rainfall water according to the requirements and achieves the purpose of meeting the design and use standards after the collected rainwater is subjected to process treatment. At present, most of rainwater diversion and filtration systems, rainwater storage systems and rainwater purification systems are composed. In addition, the rainwater utilization planning related technology application of the sponge city mainly comprises a rainwater comprehensive utilization technology, namely rainwater is collected for newly-built residential districts in the city through artificial wetlands, roof gardens, direct penetration, road collection, roof collection and other ways and is used for greening and landscape water in resident non-drinking water and the districts, so that a reclaimed water recycling system and a rainwater comprehensive utilization system are synchronously planned, designed and constructed, and the district landscape design and rainwater utilization are effectively combined; the rain and sewage diversion design is that a rainwater system is brought into the urban infrastructure planning, an independent rainwater system is planned and constructed in a newly built urban area, an old drainage pipe network system is modified, and the diverted rainwater is uniformly stored, treated and utilized; the rainwater infiltration and interception technology is that a rainwater retention pool is established to enable rainwater to gradually infiltrate downwards through an infiltration ditch, an infiltration well, an infiltration pit, a turf brick ground, a permeable concrete ground, porous asphalt and the like so as to supplement underground water in time; in addition, the roof rainwater collection technology mainly comprises the treatment links of precipitation, filtration, disinfection and the like, and the basic processes of distribution, storage, transmission, rainwater collection and the like. The water tank is used as a storage system, the rain falling pipe and the rain collecting groove are used as a collecting system, the waterproof roof is used as a flow collecting surface, precipitation and filtration are carried out before rainwater flows into the reservoir, and water is disinfected in the water tank. The mature rainwater utilization system technology is a formed product and an assembled complete set of equipment integrating rainwater collection, initial rainwater sewage interception and flow discarding, rainwater filtration, rainwater module storage, permeation, promotion, recycling and control.
The construction of the rainwater collection and utilization system plays an important role in urban water circulation and ecological systems, but a great deal of controversy still exists at present about the use of the existing urban rainwater collection and utilization system. Firstly, the technology is not advanced relatively, and the research on urban rainwater collection systems in China is relatively late, so that the urban rainwater collection systems are concentrated on certain small and local areas with serious water shortage at present. In addition, the existing rainwater treatment system is not strict enough, rainwater collection and treatment need to be carried out according to strict water quality standards, the rainwater can be put into use only after reaching standards, and disinfectants need to be strictly controlled for corresponding flocculating agents and need to regularly clean some filtering equipment. At present, rainwater treatment systems of some communities do not comply with strict regulations, so that black water in a clean water tank and some water even foam occasionally emit offensive odor of formation, and the odor and color of water are not good when the water is conveyed to a water using place through a pump, so that the water is easy to float to pedestrians to pollute clothes and even cause discomfort in sprinkling irrigation, and the later-stage maintenance cost is higher due to the fact that the water is easy to block pipelines and corrode equipment. In summary, the biggest disputes in the collection of rainwater are that the rainwater collection and utilization system has a large construction amount, high equipment cost and troublesome later maintenance, and the generated water can only be used as general domestic water which is not in direct contact with the skin, and the water only occupies a small part of the water for the residential area, so that the benefit is limited and the investment cost cannot be covered.
