Description
技术领域technical field
本实用新型涉及一种多级生态水槽和生态水塘组合系统。The utility model relates to a combination system of multi-stage ecological water tanks and ecological ponds.
背景技术Background technique
黑臭水体的“臭”是由于有机污染物含量过高，好氧微生物消耗水体中的氧气，水体转化为缺氧或厌氧状态，随后有机物腐败、分解，产生氨、硫化氢等恶臭物质。恶臭化合物是水溶性的小分子物质，难以去除。黑臭水体的“黑”是因为悬浮颗粒吸附硫化亚铁、硫化锰等，致使水体变黑。由此有机污染物和悬浮颗粒物的去除，以及水体的高浓度氨氮成为消除黑臭水体“黑”和“臭”的关键。The "stinky" of black and odorous water is due to the high content of organic pollutants, aerobic microorganisms consume oxygen in the water, the water is transformed into anoxic or anaerobic state, and then the organic matter decays and decomposes to produce odorous substances such as ammonia and hydrogen sulfide. Malodorous compounds are small water-soluble molecules that are difficult to remove. The "blackness" of black and odorous water is due to the adsorption of ferrous sulfide and manganese sulfide by suspended particles, which makes the water black. Therefore, the removal of organic pollutants and suspended particulates, as well as the high concentration of ammonia nitrogen in the water body become the key to eliminating the "blackness" and "smelly" of black and odorous water bodies.
黑臭河道水体净化包括异位治理技术和原位治理技术，前者是将河水从河道中转移到旁路的反应器中进行处理，后者是直接在受污染河道中对河水进行处理。异位处理技术包括旁路人工湿地等，能较好的去除水体悬浮物，但不能有效的提高水体原位自净能力，同时因异位处理技术占地面积大，用地受到限制而不能有效使用，尤其是在城市建成区。原位治理技术主要有河道曝气、生态浮床等，能较好地解决水体复氧能力，恢复河道自净能力，但难以去除大量的悬浮物。虽然有原位技术和异位技术的综合应用，但仍缺乏高效的、占地面积小的、原位和异位有机结合的黑臭河道水体净化技术。The water purification of black and odorous rivers includes ex-situ treatment technology and in-situ treatment technology. The former is to transfer the river water from the river to the bypass reactor for treatment, and the latter is to directly treat the river water in the polluted river. Ex-situ treatment technologies include bypass constructed wetlands, etc., which can remove suspended solids in the water body, but cannot effectively improve the in-situ self-purification ability of water bodies. At the same time, due to the large area occupied by the ex-situ treatment technology and the limited land use, it cannot be used effectively. Especially in urban built-up areas. In-situ treatment technologies mainly include river aeration and ecological floating beds, which can better solve the reoxygenation ability of water bodies and restore the self-purification ability of river courses, but it is difficult to remove a large amount of suspended solids. Although there are comprehensive applications of in-situ and ex-situ technologies, there is still a lack of efficient, small-occupied, organically combined in-situ and ex-situ water purification technologies for black and odorous rivers.

在多级生态水槽一侧河道内安装围隔18形成围隔区，围隔区水面面积为第一、二和三级生态水槽总面积的1/2到2/3，将围隔18外的河道水体进行隔挡，在出水口16至取水口2的河底安装太阳能仿生水草17，通过太阳能曝气提供好氧环境和表面附着好氧微生物膜对水体有机物进行降解。最终通过坡面多级生态水槽和河道原位围隔区串联形成水力循环系统，实现河道水体的多级循环净化。Install enclosure 18 in the channel of one side of multi-stage ecological water tank to form enclosure area, and the water surface area of enclosure area is 1/2 to 2/3 of the total area of the first, second and third-level ecological water tanks, and the outside of enclosure 18 The water body of the river is blocked, and solar biomimetic aquatic plants 17 are installed at the bottom of the river from the water outlet 16 to the water intake 2, and the aerobic environment is provided by solar aeration and the aerobic microbial film attached to the surface degrades the organic matter in the water body. Finally, a hydraulic circulation system is formed by connecting the multi-stage ecological tanks on the slope surface and the in-situ enclosure of the river in series to realize the multi-stage circulation and purification of the river water.
填料配方和菌剂包、种植的植物种类和数量可以根据水体污染特征针对性调整；生态水槽级数也可依据岸坡实际地形进行调整，不局限于本实施例的描述。The filler formula, bacterial agent package, plant species and quantity can be adjusted according to the characteristics of water pollution; the number of ecological water tanks can also be adjusted according to the actual topography of the bank slope, and is not limited to the description of this embodiment.
本实施例利用黑臭水体河道形成原位围隔区的原位净化和坡面多级生态水槽的异位净化有机结合，同时通过太阳能水泵形成水力循环系统，实现干湿交替运行，通过定期对生态水槽进行更换填料和植物收割，可以有效去除黑臭水体污染物，消除河道黑臭。In this embodiment, the in-situ purification of the in-situ enclosure area formed by the black and odorous water channel and the ex-situ purification of the multi-stage ecological water tank on the slope are organically combined. At the same time, the solar water pump is used to form a hydraulic circulation system to realize the alternating operation of dry and wet. Replacing fillers and harvesting plants in ecological tanks can effectively remove black and odorous water pollutants and eliminate black and odorous rivers.
本实施例多级生态水槽和生态水塘组合系统的效果在于将河道原位和异位治理相结合，充分利用河岸建设多级生态水槽和围隔串联组合系统，高效净化黑臭河道水质，避免了异位治理技术用地受到限制的问题，同时坡面多级生态水槽对河道岸坡起到了很好的护坡作用。The effect of the combination system of multi-level ecological water tanks and ecological ponds in this embodiment is to combine in-situ and off-site treatment of the river, make full use of the river bank to build a multi-level ecological water tank and enclosure series combination system, efficiently purify the water quality of black and odorous rivers, and avoid It solves the problem of limited land use for off-site treatment technology, and at the same time, the multi-level ecological water tank on the slope plays a very good role in slope protection for the river bank slope.
坡面多级生态水槽的多基质填料(包括卵砾石、钢渣、粗砂、土壤等)和植物根系表面生上了大量微生物并形成生物膜，水体中的固体悬浮物被钢渣和粗砂组合填料在第一级生态水槽吸附截留，有机质、通过填料区域微生物吸收分解而去除，氨通过跌水提供的复氧环境，利用硝化细菌进行硝化作用，转变为硝态氮，同时在第二、三级生态水槽的底层填料中配以反硝化菌剂包，并以石灰石提供反硝化作用所需的弱碱性环境，强化反硝化作用，硝态氮最后转变为氮气而去除。采用太阳能提升泵提水，昼间工作，夜间停止，一方面实现了生态水槽的间歇进水，干湿交替运行，为好氧菌和厌氧菌生长提供环境，同时节省了能源。The multi-matrix filler (including pebbles, steel slag, coarse sand, soil, etc.) of the multi-level ecological water tank on the slope and the surface of the plant roots grow a large number of microorganisms and form biofilms, and the suspended solids in the water are filled by the combination of steel slag and coarse sand. Adsorption and interception in the first-level ecological water tank, organic matter is removed through the absorption and decomposition of microorganisms in the filler area, and ammonia is converted into nitrate nitrogen by nitrifying bacteria in the re-oxygenation environment provided by the falling water. The bottom filler of the ecological water tank is equipped with a denitrifying bacteria agent package, and limestone is used to provide the weakly alkaline environment required for denitrification to strengthen denitrification, and the nitrate nitrogen is finally converted into nitrogen and removed. The solar lifting pump is used to lift water, work during the day and stop at night. On the one hand, it realizes the intermittent water intake of the ecological tank, and the alternating operation of dry and wet, providing an environment for the growth of aerobic and anaerobic bacteria, and saving energy at the same time.
河道中水流循环路径上布置人工水草，其上附着生物膜中形成好氧微生物群落，有效防止水体厌氧消化，减少控制黑臭水体恶臭气体的产生。Artificial aquatic plants are arranged on the water circulation path in the river, and aerobic microbial communities are formed in the biofilm attached to them, which can effectively prevent anaerobic digestion of water bodies and reduce and control the generation of odorous gases in black and odorous water bodies.
多级水槽处理后尾水回到河道表层，与取水口底部温度较低的水体，形成了水体循环路线，实现了河道水体表层水和底层水上下交替，水体水温受到调节，可抑止黑臭水体微藻大量生长繁殖。After the multi-stage tank treatment, the tail water returns to the surface of the river, and forms a water circulation route with the water at the bottom of the water intake with a lower temperature, realizing the alternation of the surface water and the bottom water of the river, and the water temperature is adjusted, which can suppress black and odorous water Microalgae grow in abundance.
在坡面多级生态水槽填料吸附、植物-微生物吸附吸收降解、原位人工水草生物膜吸收降解，以及水动力循环等协同作用下，实现了黑臭水体污染物的高效去除，消除了河道黑臭。Under the synergistic effects of multi-stage ecological tank filler adsorption on the slope surface, plant-microbial adsorption, absorption and degradation, in-situ artificial aquatic plant biofilm absorption and degradation, and hydrodynamic cycle, the efficient removal of black and odorous water pollutants has been realized, and the black water in the river has been eliminated. Smelly.
