Description
技术领域 technical field
本发明涉及一种污水处理装备，具体来说涉及一种自动复氧生活污水生态土壤净化床。 The invention relates to sewage treatment equipment, in particular to an automatic reoxygenation domestic sewage ecological soil purification bed. the
背景技术 Background technique
我国中小城镇发展迅速，目前我国有中小城镇两万多个，但中小城镇的生活污水处理率还不到1％，预计今后我国80％以上的生活污水将来自中小城镇。因此，开发一种适合我国国情的中小城镇污水工艺成为我国科学工作者的一项重要研究课题. my country's small and medium-sized towns are developing rapidly. At present, there are more than 20,000 small and medium-sized cities and towns in my country, but the domestic sewage treatment rate of small and medium-sized cities and towns is less than 1%. It is estimated that more than 80% of domestic sewage in my country will come from small and medium-sized cities and towns in the future. Therefore, it has become an important research topic for Chinese scientists to develop a kind of small and medium-sized town sewage process suitable for my country's national conditions.
目前，我国绝大部分城市污水厂均采用传统的二级活性污泥法处理工艺。这种工艺投资高，能耗大，运行管理要求也高。由于我国经济发展水平不高，能源短缺，许多地方尤其是中小城市和乡村缺乏具有一定操作管理经验和技术水平的人员，同时我国的乡镇企业迅猛发展，对当地造成了严重的环境污染，因此在我国大力开发具有高效、简易、低耗的污水处理技术具有很大意义 At present, the vast majority of urban sewage plants in my country adopt the traditional secondary activated sludge treatment process. This process requires high investment, high energy consumption, and high requirements for operation and management. Due to the low level of economic development and energy shortage in our country, many places, especially small and medium-sized cities and villages, lack personnel with certain operational management experience and technical level. At the same time, the rapid development of my country's township enterprises has caused serious environmental pollution to the local area. It is of great significance for our country to vigorously develop efficient, simple and low-consumption sewage treatment technology
污水的土壤处理系统以其构造简单，维护容易，基建费和运行费低廉，节省能源和资源等特点受到广泛发展。 The sewage soil treatment system has been widely developed due to its simple structure, easy maintenance, low infrastructure and operating costs, and energy and resource saving. the
目前常见的生活污水土壤处理技术及其缺点如下： The current common domestic sewage soil treatment technologies and their disadvantages are as follows:
(1)污水砂滤处理系统。一般采用填砂作为介质，让污水经过砂体渗滤排出系统，达到净化目的。缺点主要是水力负荷比较低，处理能力小。 (1) Sewage sand filter treatment system. Generally, sand filling is used as the medium, and the sewage is filtered out of the system through the sand body to achieve the purpose of purification. The main disadvantage is that the hydraulic load is relatively low and the processing capacity is small. the
(2)腐化池+土地截滤。这类反应器的在欧美等国应用较多，国内应用较少。但其也同样存在占地面积大，运行维护困难等缺点。 (2) Corrosion pool + land interception. This type of reactor is widely used in Europe, America and other countries, but less in China. However, it also has the disadvantages of large footprint and difficult operation and maintenance. the
(3)联合式土壤生态处理系统。这一类反应器在一定程度上综合了土壤和生化处理的优点。但由于生化反应时间过长，运行成本较高，并且由于设备较多，管理复杂。 (3) Combined soil ecological treatment system. This type of reactor combines the advantages of soil and biochemical treatment to a certain extent. However, due to the long biochemical reaction time, the operating cost is high, and due to the large number of equipment, the management is complicated. the
