Diatomite can be used as a sewage treatment agent after purification, modification, activation and expansion. Diatomite as a sewage treatment agent is technically and economically feasible, and has a good prospect of popularization and application. This article analyzes the current characteristics of urban sewage water quality, water volume and other characteristics, and proposes sewage treatment technology suitable for China’s national conditions. The technology of diatomite treatment of urban sewage is a physicochemical sewage treatment technology. High-efficiency modified diatomite sewage treatment agent is the key to this technology. On this basis, with reasonable process flow and process facilities, this technology can achieve high efficiency. , The purpose of treating urban sewage stably and cheaply. But because this is a new technology, there are still some problems to be solved in both theoretical and practical engineering applications.
The discharge of industrial wastewater and urban domestic sewage has caused serious environmental pollution. Therefore, the treatment of wastewater and sewage has always been a hot issue. In terms of comprehensive treatment, the use of diatomaceous earth to treat industrial wastewater or the production of drinking water has a history of nearly 20 years of research. According to investigations, as early as 1915, people used diatomaceous earth in small water treatment devices to produce drinking water. water. In foreign countries, diatomaceous earth sewage treatment agents are used as a variety of filter aids to produce and apply, including drinking water, swimming pool water, bathroom water, hot springs, industrial water, boiler circulating water, and industrial wastewater filtration and treatment.
