Description

Technical Field

[0001] The invention relates to a filler installation device for sewage treatment equipment. Background Art

[0002] With the increasing industrialization and urbanization in my country, the wastewater treatment industry has attracted considerable attention and become an indispensable component of social development and progress. Furthermore, the wastewater treatment industry is closely linked to ecological and environmental protection and is crucial to the development of a green China. After decades of development, the activated sludge process has become the preferred treatment method for urban wastewater treatment plants, spawning a variety of different process types. However, in low-temperature environments, the activity of enzymes involved in biochemical reactions is inhibited, slowing the metabolic rate of microorganisms. This reduces wastewater treatment efficiency and puts effluent at risk of exceeding standards. To address the poor treatment performance of activated sludge processes at low temperatures, researchers have proposed methods such as extending sludge age, adding functional bacterial agents, and adding biofillers. These methods have proven effective in the actual operation of wastewater treatment plants. The addition of biofillers can provide microbial attachment and growth sites, extend sludge age, and promote interaction between microorganisms and fillers, thereby improving system treatment efficiency. Consequently, a variety of biofillers have been developed and widely used.

[0003] At present, the addition or installation methods of biological fillers are divided into mobile and fixed types. Among them, the mobile type has high requirements for the flow state and operation control of the biochemical pool, and is easily lost with the effluent. It is mostly used in laboratories or small-scale pilot equipment. Fixed installation avoids the problems of uneven distribution and easy loss of fillers, and has become the preferred installation method for biological fillers in sewage treatment plants. However, biological fillers need regular maintenance during operation and need to be replaced after the service life expires. This not only increases the workload of operators, but also increases the operation and maintenance costs of sewage treatment plants. At present, the installation, maintenance and replacement of biological fillers require the use of large machinery and consumes a lot of manpower. Summary of the Invention
