Description
技术领域technical field
本实用新型涉及水环境保护与治理领域，尤其涉及一种吸附—电解—曝气协同一体化处理富营养化水体的装置。The utility model relates to the field of water environment protection and treatment, in particular to a device for synergistically integrating adsorption-electrolysis-aeration to treat eutrophic water bodies.
背景技术Background technique
湖泊富营养化是当今世界面临的重大环境问题。湖库水体富营养化恶化水质，诱发“水质性”缺水危机，降低水资源综合利用效率和安全供水保障能力，极大削弱了水资源对国民经济社会发展的战略支撑作用。Eutrophication of lakes is a major environmental problem facing the world today. The eutrophication of lakes and reservoirs deteriorates water quality, induces a "water quality" water shortage crisis, reduces the comprehensive utilization efficiency of water resources and the ability to guarantee safe water supply, and greatly weakens the strategic support role of water resources for national economic and social development.
目前水体富营养化治理主要通过控制藻类及消除过量氮磷等营养物质相结合的方式。对藻类控制来说，通常采用打捞、机械除藻或化学除藻等方法；过量营养物质削减，大多采用清水稀释、植物吸收净化等措施。这些藻类防治措施耗时耗力，应急处置能力较差；过量营养物质削减通常需要配套建设引水工程或植物修复工程，引水工程耗费大量清水，植物修复见效慢。由此可见，在外源截污背景下，采用合适的工艺方法快速削减水体中的氨氮和磷，将水体中的氨氮和磷含量，以及藻类密度降低至可接受水平，是今后治理河湖富营养化问题的重要方向。At present, the treatment of eutrophication in water bodies is mainly through the combination of controlling algae and eliminating excess nitrogen, phosphorus and other nutrients. For algae control, methods such as salvage, mechanical algae removal or chemical algae removal are usually used; excess nutrients are mostly reduced by water dilution, plant absorption and purification, and other measures. These algae control measures are time-consuming and labor-intensive, and their emergency response capabilities are poor. The reduction of excess nutrients usually requires the construction of water diversion projects or phytoremediation projects. Water diversion projects consume a lot of water, and phytoremediation is slow to take effect. It can be seen that under the background of exogenous pollution interception, adopting appropriate technological methods to quickly reduce the ammonia nitrogen and phosphorus in the water body, reduce the ammonia nitrogen and phosphorus content in the water body, and the density of algae to an acceptable level is the key to the future treatment of eutrophication in rivers and lakes. important direction of the problem.
实用新型名称为“移动式富营养化水体处理装置”的中国专利(申请号：201210193361.3)公布了移动式富营养化水体处理装置，该装置包括集水池、厌氧池、好氧池、移动床生物膜反应器、二沉池、催化氧化池和清水池等处理装置。该专利整体处理工艺流程类似于污水处理处理装置设计复杂；富营养化水体处理装置处理后排出的方式属于异位处理，处理水量有限；采用移动床生物膜反应器，其微生物处理富营养化水体需要较长的停留时间且运行维护复杂。The Chinese patent (application number: 201210193361.3) with the utility model name "Mobile Eutrophication Water Treatment Device" discloses a mobile eutrophication water treatment device. Treatment devices such as biofilm reactors, secondary sedimentation tanks, catalytic oxidation tanks and clean water tanks. The overall treatment process of this patent is similar to the complex design of sewage treatment and treatment equipment; the eutrophic water treatment equipment discharges after treatment is an ex-situ treatment, and the amount of treated water is limited; a moving bed biofilm reactor is used, and its microorganisms treat eutrophic water. It requires a long residence time and complicated operation and maintenance.
在实用新型名称为“一种高效磁性除藻和增氧曝气结合的景观水体水华净化船”的中国专利(申请号：201010238112.2)中，公布了一种高效新型景观水体水华处理用船，其原理是当景观水体吸入船只时，期间投加铁磁性物质、混凝剂和助凝剂，使悬浮物、胶体物质、藻类和总磷等形成可作用于磁场的微絮颗粒，然后通过磁力将其从水体中分离。该专利中把水吸入船只处理相当于异位处理，处理能力有限，且投加絮凝剂、助凝剂、磁铁等使得处理工艺更加繁琐。In the Chinese patent (Application No.: 201010238112.2) titled "A Landscape Water Bloom Purification Boat Combining High-Efficiency Magnetic Algae Removal and Oxygen-increasing Aeration", a new type of high-efficiency boat for landscape water bloom treatment was announced , the principle is that when the landscape water body is sucked into the ship, ferromagnetic substances, coagulants and coagulants are added during the period to make suspended solids, colloidal substances, algae and total phosphorus form micro-floc particles that can act on the magnetic field, and then pass through Magnetic force separates it from the body of water. In this patent, the treatment of water sucked into the ship is equivalent to ex-situ treatment, and the treatment capacity is limited, and the addition of flocculants, coagulants, magnets, etc. makes the treatment process more cumbersome.
在实用新型名称为“一种移动式富营养化水体生态修复装置”的中国专利(申请号：201010238112.2)中，公布了一种可以通过迁移的移动式富营养化水体生态修复装置，该装置主要由光催化气体发生装置、填料层、流水层组成，利用填料层对富营养化水体进行净化，水中加臭氧发生器产生臭氧和光催化气体产生光氢离子，对水质实行杀菌消毒。整个装置可由车载运输到他处。该移动生态修复装置是一种塑料净化罐，富营养化水体自上至下处理，容易发生堵塞，而且采用臭氧及光催化装置成本及处理成本较高。In the Chinese patent (Application No.: 201010238112.2) of the utility model titled "A Mobile Eutrophic Water Ecological Restoration Device", a mobile eutrophic water ecological restoration device that can be migrated is disclosed. It consists of a photocatalytic gas generating device, a packing layer, and a flowing water layer. The packing layer is used to purify the eutrophic water body. An ozone generator is added to the water to generate ozone and photocatalytic gas to generate photohydrogen ions to sterilize the water quality. The entire device can be transported to other places by vehicle. The mobile ecological restoration device is a plastic purification tank, and the eutrophic water body is treated from top to bottom, which is prone to blockage, and the cost and treatment cost of ozone and photocatalytic devices are relatively high.
现有富营养化水体治理技术及装置或是采用生物方法恢复水体生态功能，耗时较长，生物生存条件要求苛刻；或是采用厌氧池、好氧、生物膜等组合装置进行处理，设计复杂，微生物处理富营养化水体需要较长的停留时间且运行维护复杂，处理成本较高。并且，现有装置的功能都过于单一化，不能同时将富营养化水体中的氮磷污染物及藻类同时去除，装置中的各个净化单元都是独立运行的，尚未见到有净化单元之间协同作用的例子。Existing eutrophication water treatment technologies and devices either use biological methods to restore the ecological functions of water bodies, which takes a long time and require harsh biological living conditions; Complex, microbial treatment of eutrophic water requires a long residence time and complex operation and maintenance, and the treatment cost is high. Moreover, the functions of the existing devices are too simple to remove the nitrogen, phosphorus pollutants and algae in the eutrophic water body at the same time. Each purification unit in the device operates independently, and there is no connection between the purification units. Example of synergy.
在实用新型名称为“封闭水域大型移动式水质净化系统”的中国专利(专利号：201110308276.2)中，公布了一种封闭水域大型移动式水质净化系统，该系统上设有过滤单元、吸附单元、微电流电解离子释放单元、曝气单元等水质处理装置，通过各个水质处理单元与水域水体的直接接触，对水体中污染物进行处理。该装置由于采用的水处理技术主要为物理化学技术，相比于前述的生物修复技术，具有处理速度快、处理能力强等优点。该装置对吸附、曝气与微电流电解进行了整体集成，根据水域水体的污染类型，选择性地布设其中的一种或几种单元。但是系统涉及的吸附、曝气与微电流电解独立设计、布置和运行，未考虑与发挥各个单元之间的协同和耦合作用。因此，开发一种结构简单、能充分发挥各个单元之间协同功能、有效消除富营养化水体中的氮磷污染物及藻类的净化技术及装置非常必要。In the Chinese patent (Patent No.: 201110308276.2) of the utility model titled "Large-scale Mobile Water Purification System for Closed Waters", a large-scale mobile water purification system for closed waters is disclosed. The system is equipped with a filter unit, an adsorption unit, Micro-current electrolysis ion release unit, aeration unit and other water quality treatment devices, through the direct contact between each water quality treatment unit and the water body of the water, treat the pollutants in the water body. Since the water treatment technology adopted by the device is mainly physical and chemical technology, compared with the aforementioned bioremediation technology, it has the advantages of fast processing speed and strong processing capacity. The device integrates adsorption, aeration and micro-current electrolysis as a whole, and one or several units are selectively arranged according to the pollution type of the water body. However, the adsorption, aeration and micro-current electrolysis involved in the system are independently designed, arranged and operated, without considering and exerting the synergistic and coupling effects between each unit. Therefore, it is very necessary to develop a purification technology and device that has a simple structure, can give full play to the synergistic functions of each unit, and effectively eliminate nitrogen, phosphorus pollutants and algae in eutrophic water bodies.
