Wastewater treatment equipment for county-level hospitals: technology, challenges and prospects.
With the advancement of medical technology and the increasing improvement of county-level hospital facilities, the generation and treatment of medical wastewater has become an environmental problem that cannot be ignored. As a key link to solve this problem, the sewage treatment equipment of county-level hospitals is worthy of in-depth research on its technical development, application status and future challenges.
1. Technological development and current situation.
In the early days, county-level hospitals mainly relied on simple methods such as natural sedimentation and filtration, but this method was inefficient and difficult to meet increasingly stringent environmental protection requirements. With the development of science and technology, a variety of sewage treatment technologies and equipment have emerged. For the special wastewater composition of the hospital, a variety of technical means such as biological treatment, chemical treatment and physical treatment are mainly adopted. These technologies effectively remove pathogens, harmful chemicals and suspended solids from wastewater through multiple links such as pretreatment, primary treatment and secondary treatment.
At present, the sewage treatment equipment commonly used in county-level hospitals mainly includes grilles, sedimentation tanks, aeration tanks, disinfection devices, etc. These plants achieve continuous and stable wastewater treatment through an automatic control system. In addition, some advanced equipment such as membrane bioreactor (MBR) and activated carbon adsorption have also been gradually applied in county-level hospitals.
2. Challenges.
Although technological progress has promoted the upgrading of sewage treatment equipment in county-level hospitals, there are still many challenges. First of all, the equipment investment is large and the operating cost is high. The introduction and maintenance of advanced equipment requires a large amount of capital investment, which brings great economic pressure to county-level hospitals. Secondly, there is a shortage of professional operators. The normal operation of equipment requires professional maintenance and management, and county-level hospitals often lack such personnel. In addition, the high failure rate of equipment and the difficulty of accessories are also common problems encountered in the operation of sewage treatment equipment in county-level hospitals.
3. Prospects**
In the face of challenges, the future sewage treatment equipment of county-level hospitals will develop in the direction of more intelligent, automated and energy-saving. Intelligent technologies such as the Internet of Things and big data will be combined with sewage treatment equipment to achieve functions such as remote monitoring, fault warning and automatic adjustment. At the same time, new sewage treatment methods such as biotechnology and electrochemistry will further expand their applications and improve treatment efficiency. In terms of energy saving, high-efficiency and low-energy wastewater treatment equipment will become the mainstream, and operating costs will be reduced through optimized design.
IV. Conclusions**
As a product of the integration of medical treatment and environment, the technical development and practical application of sewage treatment equipment in county-level hospitals are of great significance for environmental protection and public health. In the face of the current problems and challenges, it is necessary to further strengthen technological innovation, improve policy support and improve professional management level to promote the continuous improvement and wide application of sewage treatment equipment in county-level hospitals. This is not only the responsibility of the hospital itself, but also requires the common attention and efforts of the whole society.
