Solar anaerobic granular sludge circulation reactor

Abstract

A solar anaerobic granular sludge circulation reactor belongs to the environmental engineering field. The reactor is characterized by comprising a water inflow and distribution chamber, a granular sludge reaction chamber, a precipitation and filtration chamber, a sludge circulation system, a triphase separator and a solar collector enclosure. The water inflow and distribution chamber is arranged on the lower part of the granular sludge reaction chamber, the precipitation and filtration chamber and the granular sludge reaction chamber are of concentric nested structure, the solar collector enclosure is arranged on the upper part of the triphase separator, the granular sludge reaction chamber is communicated with the precipitation and filtration chamber via an output pipe of the granular sludge reaction chamber, and the water inflow and distribution chamber is communicated with the granular sludge reaction chamber via a permeable layer of the water inflow and distribution chamber. The circulation reactor not only increases the biodegradation efficiency and lowers the operating cost, but also achieves the aim of improving the effluent quality. The circulation reactor can be used for treating high-concentration sewage.

Description

technical field [0001] The invention belongs to the field of environmental engineering and relates to sewage treatment technology, in particular to a solar anaerobic granular sludge circulation reactor. technical background [0002] In the case of increasingly scarce water resources in our country, the recycling of sewage has become the main way to solve the shortage of water in cities and towns, and it is also an important means to reduce the pollution of water resources and the environment. Therefore, it is of great significance to vigorously research and develop sewage resource utilization technology for our country to realize the strategic decision of sewage resource utilization. [0003] Anaerobic biological treatment technology is one of the fastest-growing technologies in the field of sewage resource utilization in recent years. Through the pre-treatment of this process technology, it can greatly reduce the organic pollutants in sewage and reduce operating costs. UAS...
