Abstract

The invention discloses a denitrification filter tank system applicable to advanced wastewater treatment. The system comprises a carbon source addition control unit and a denitrification deep bed filter tank unit, wherein the carbon source addition control unit comprises a central controller, a thermometer, a BOD water inlet detection instrument, a water inlet total nitrogen analyzer, a mixing pool, an added chemical metering pump and a carbon source adding pool; the central controller is connected with the thermometer, the BOD water inlet detection instrument, the water inlet total nitrogen analyzer and the added chemical metering pump, and the central controller provides data collected by the thermometer, the BOD water inlet detection instrument and the water inlet total nitrogen analyzer for the added chemical metering pump. The denitrification filter tank system has the advantages that tail water of a sewage plant is treated with the system, yielding water is obvious superior to the first class standard A, and the market generalization performance is excellent.

Description

technical field [0001] The invention belongs to the technical field of environmental protection and relates to a waste water treatment system, in particular to a denitrification filter system suitable for advanced treatment of sewage. technical background [0002] In recent years, with the rapid development of my country's economy and society, environmental problems have become more and more prominent, and have become the focus of general attention of the central and local governments. Taking the widely concerned "Three Lakes" (Taihu Lake, Chaohu Lake and Dianchi Lake) as an example, a large amount of pollutants such as nitrogen and phosphorus were discharged into the water body, which aggravated the problem of eutrophication, resulting in frequent blooms of cyanobacteria, which seriously affected the Production and life of local residents. In order to protect the environment and ensure the sustainable development of the economy and society, the national environmental prote...
