Description
技术领域 technical field
本发明涉及污水处理技术领域，具体涉及一种水体循环流动充氧的生态塘系统，用于增加生态塘内水体流动性及水中溶解氧，塘内分区域形成缺氧区、好氧区和深度净化区，充分发挥细菌、藻类和植物对污水的联合净化作用。The invention relates to the technical field of sewage treatment, in particular to an ecological pond system for circulating and oxygenating the water body, which is used to increase the fluidity of the water body in the ecological pond and the dissolved oxygen in the water, and forms an anoxic zone, an aerobic zone and a deep purification zone in sub-regions in the pond , Give full play to the joint purification effect of bacteria, algae and plants on sewage.
背景技术 Background technique
利用生态处理系统对面源污水进行净化处理，实现村域水环境的整体改善成为控制农村面源污染问题的重要手段。生态塘是通过菌藻共生系统和植物净化系统对污水进行处理的工程设施，目前广泛与人工湿地联合使用，组成复合式生态处理技术。Using ecological treatment system to purify non-point source sewage and realize the overall improvement of village water environment has become an important means to control rural non-point source pollution. The ecological pond is an engineering facility that treats sewage through the symbiosis system of bacteria and algae and the plant purification system. It is currently widely used in combination with constructed wetlands to form a composite ecological treatment technology.
然而，生态塘系统由于停留时间长，水体流动慢，往往水中复氧能力差，水中的溶解氧不足，单纯依靠植物根系对氧的传递释放是不能满足细菌对有机物的好氧分解需要，特别是在夜间，藻类呼吸作用占据主导，水体中长时间处于缺氧状态，菌藻共生系统往往不能保持平衡，藻类大量繁殖、生长和消亡，造成水中溶解氧较低，有机物和氨氮去除效果较差，出水中固体悬浮物含量过高。因此，如何加强水体流动性，增加水中溶解氧浓度，抑制藻类生长，保持菌藻共生平衡，一直是生态塘技术推广应用需要解决的重要问题。However, due to the long residence time and slow water flow in the ecological pond system, the reoxygenation capacity of the water is often poor, and the dissolved oxygen in the water is insufficient. Relying solely on the transfer and release of oxygen by plant roots cannot meet the needs of bacteria for aerobic decomposition of organic matter, especially At night, algae respiration dominates, and the water body is in a state of hypoxia for a long time. The symbiosis system of bacteria and algae often cannot maintain balance. The algae multiply, grow and die in large numbers, resulting in low dissolved oxygen in the water, and poor removal of organic matter and ammonia nitrogen. The content of suspended solids in the effluent is too high. Therefore, how to enhance the fluidity of water bodies, increase the concentration of dissolved oxygen in water, inhibit the growth of algae, and maintain the symbiotic balance of bacteria and algae has always been an important problem to be solved in the promotion and application of ecological pond technology.

与现有技术相比，本发明具有以下优点：Compared with the prior art, the present invention has the following advantages:
1、本发明利用太阳能清洁能源将污水气提返回初始生态塘中，水体加速循环，增加大气复氧，促进了生态塘中菌藻共生系统的良性循环。同时，在一个生态塘中依次形成缺氧区、好氧区和深度处理区，充分发挥各阶段对于水中污染去除的优势，在缺氧区对于面源污水中的固体悬浮物、有机物和硝态氮去除效果明显，并增加了水体的生化性，在好氧区对于水中氨氮、有机物以及增加水中溶解氧的效果明显，在深度处理区对于水中氮磷、固体悬浮物以及进一步降解有机物效果明显。1. The present invention uses solar clean energy to lift the sewage back into the initial ecological pond, accelerates the circulation of the water body, increases atmospheric reoxygenation, and promotes a virtuous cycle of the symbiotic system of bacteria and algae in the ecological pond. At the same time, an anoxic zone, an aerobic zone, and an advanced treatment zone are sequentially formed in an ecological pond to give full play to the advantages of each stage in water pollution removal. The nitrogen removal effect is obvious, and the biochemical properties of the water body are increased. In the aerobic zone, the effect on ammonia nitrogen and organic matter in the water and the increase in dissolved oxygen in the water are obvious. In the advanced treatment zone, the effect on nitrogen, phosphorus, solid suspended matter and further degradation of organic matter in the water is obvious.
2、本发明通过太阳能和蓄电池交替运行，使得生态塘系统在夜间也将发挥更好的优势。一般而言夜间微生物和植物的呼吸作用占据主导，水中氧气成分明显降低，将严重影响夜间污水的处理效果，本系统可以克服以上困难，提高夜间水中的溶解氧浓度。并且，在该生态塘系统中，只采用一台以太阳能为主的小功率空气泵，动力消耗低，大大简化了运行维护的复杂程序，降低了建设和运行成本。2. The present invention operates alternately through solar energy and batteries, so that the ecological pond system will also play better advantages at night. Generally speaking, the respiration of microorganisms and plants is dominant at night, and the oxygen content in water is significantly reduced, which will seriously affect the treatment effect of sewage at night. This system can overcome the above difficulties and increase the concentration of dissolved oxygen in water at night. Moreover, in this ecological pond system, only one low-power air pump mainly based on solar energy is used, which has low power consumption, greatly simplifies the complex procedures of operation and maintenance, and reduces construction and operation costs.

与现有技术相比，本发明具有以下优点：Compared with the prior art, the present invention has the following advantages:
1、本发明利用太阳能清洁能源将污水气提返回初始生态塘中，水体加速循环，增加大气复氧，促进了生态塘中菌藻共生系统的良性循环。同时，在一个生态塘中依次形成缺氧区、好氧区和深度处理区，充分发挥各阶段对于水中污染去除的优势，在缺氧区对于面源污水中的固体悬浮物、有机物和硝态氮去除效果明显，并增加了水体的生化性，在好氧区对于水中氨氮、有机物以及增加水中溶解氧的效果明显，在深度处理区对于水中氮磷、固体悬浮物以及进一步降解有机物效果明显。1. The present invention uses solar clean energy to lift the sewage back into the initial ecological pond, accelerates the circulation of the water body, increases atmospheric reoxygenation, and promotes a virtuous cycle of the symbiotic system of bacteria and algae in the ecological pond. At the same time, an anoxic zone, an aerobic zone, and an advanced treatment zone are sequentially formed in an ecological pond to give full play to the advantages of each stage in water pollution removal. The nitrogen removal effect is obvious, and the biochemical properties of the water body are increased. In the aerobic zone, the effect on ammonia nitrogen and organic matter in the water and the increase in dissolved oxygen in the water are obvious. In the advanced treatment zone, the effect on nitrogen, phosphorus, solid suspended matter and further degradation of organic matter in the water is obvious.
2、本发明通过太阳能和蓄电池交替运行，使得生态塘系统在夜间也将发挥更好的优势。一般而言夜间微生物和植物的呼吸作用占据主导，水中氧气成分明显降低，将严重影响夜间污水的处理效果，本系统可以克服以上困难，提高夜间水中的溶解氧浓度。并且，在该生态塘系统中，只采用一台以太阳能为主的小功率空气泵，动力消耗低，大大简化了运行维护的复杂程序，降低了建设和运行成本。2. The present invention operates alternately through solar energy and batteries, so that the ecological pond system will also play better advantages at night. Generally speaking, the respiration of microorganisms and plants is dominant at night, and the oxygen content in water is significantly reduced, which will seriously affect the treatment effect of sewage at night. This system can overcome the above difficulties and increase the concentration of dissolved oxygen in water at night. Moreover, in this ecological pond system, only one low-power air pump mainly based on solar energy is used, which has low power consumption, greatly simplifies the complex procedures of operation and maintenance, and reduces construction and operation costs.
以上所述，仅是本发明的较佳实施实例而已，并非对本发明做任何形式上的限制，任何未脱离本发明技术方案的内容，依据本发明的技术实质对以上实施实例所作的任何简单修改、等同变化与修饰，均属于本发明技术方案的范围。The above is only a preferred implementation example of the present invention, and is not intended to limit the present invention in any form, any content that does not deviate from the technical solution of the present invention, any simple modification made to the above implementation examples according to the technical essence of the present invention , equivalent changes and modifications all belong to the scope of the technical solution of the present invention.
