Description

Technical Field

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

[0002] With the intensification of industrialization and urbanization in my country, the sewage treatment industry has attracted much attention and has become an indispensable part of social development and progress. At the same time, the sewage treatment industry is closely related to ecological environmental protection and is crucial to the construction of a green China. After decades of development, the activated sludge process has become the preferred treatment process for urban sewage treatment plants, and has derived a variety of process forms. However, under low temperature conditions, the activity of enzymes involved in biochemical reactions is inhibited, and the metabolic rate of microorganisms becomes slow, resulting in reduced treatment efficiency of sewage treatment plants and the risk of effluent exceeding the standard. In order to solve the problem of poor treatment effect of activated sludge process in low temperature period, researchers have proposed methods such as extending sludge age, adding functional bacterial agents, and adding biological fillers, which have played a certain role in the actual operation of sewage treatment plants. Among them, adding biological fillers can provide microorganisms with attachment and growth points, extend sludge age, and promote the interaction between microorganisms and fillers, thereby improving the treatment efficiency of the system. Therefore, a variety of biological fillers have been developed and widely used.

[0003] At present, the addition or installation methods of biological fillers are divided into mobile and fixed types. 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 to be regularly inspected and maintained 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 consume a lot of manpower. Summary of the invention
