Problems solved by technology

However, traditional bio-discs have problems such as low organic load, poor sanitary conditions, and poor denitrification effect in the sewage treatment process.
[0003] Activated sludge method is a traditional method in sewage biological treatment technology. It has a good effect on removing organic matter. It can effectively remove N and P in sewage when combined with other processes, and has low investment and operating costs. However,

Abstract

The invention discloses a combined type biological rotating disk treatment device which is composed of a water inlet tank, a biological rotating disk reactor, a biological drop filter tank and the like. The invention further discloses a method using the combined type biological rotating disk treatment device to treat sewage. Sewage firstly enters the water inlet tank, is pumped by a jet pump and enters all section of a biological rotating disk through a plurality of pipelines. After the sewage is nitrified and denitrified by the biological rotating disk, the sewage falls into the biological drip filter tank through a water distribution plate. After being filtered, one part of the sewage is drained, and one part of the sewage flows back to the water inlet tank. A casing is covered on the biological rotating disk reactor, the jet pump can supply oxygen fro the biological rotating disk reactor, and air in the tank is filtered by the biological drop filter tank to be drained. A dissolved oxygen and liquid level control device are arranged in the tank. The jet pump is controlled to be opened according to dissolved oxygen and water inlet liquid level. Thus, low-energy-consumption running is achieved.

Description

technical field [0001] The invention relates to environmental protection engineering equipment, in particular to a sewage treatment device with a biological turntable as the core treatment process and a sewage treatment method using the same. Background technique [0002] In sewage biological treatment equipment, biological turntables have been used since the 1950s and 1960s. Biological turntables are a biofilm wastewater treatment technology. Microbes with a long survival time can grow on the biological disks, and the sludge age is long. It has a long resistance to impact load capacity and has good handling effect. In terms of process and maintenance operation, biological discs have the advantages of high microbial concentration, no need to return sludge, low power consumption, and low operating costs. However, traditional bio-discs have problems such as low organic load, poor sanitary conditions, and poor denitrification effect in the sewage treatment process. [0003] A...
