Description

Anaerobic baffle plate equipment or structure heated by solar technology
Technical Field
The invention relates to anaerobic baffle plate equipment or a structure heated by a solar technology, belonging to the technical field of solar utilization and wastewater treatment.
Background
In recent years, the 3 rd generation anaerobic reactors represented by anaerobic baffled plates (ABR) have been increasingly emphasized in the treatment of sewage with good biochemical properties due to their advantages of strong biological solid retention capacity, fast start-up speed, good hydraulic mixing conditions, and the like. However, the wastewater treatment efficiency of the treatment mode is greatly influenced by the change of the temperature of the external environment. The temperature is higher in summer in most areas of our country, the ABR operation requirement can be met under natural conditions, but the temperature in three seasons of autumn, winter and spring (mainly late autumn, winter and early spring) is lower than 20 ℃, even lower than minus 10 ℃ in winter, so that the ABR facility treatment effect is greatly reduced. And the cost is too high by adopting natural gas or electric energy for heating. Therefore, research and development of ABR equipment or structures having a heating function without using natural gas or using as little electric energy as possible, and maintaining the temperature at an appropriate temperature of 20 ℃ or more in winter, become a key problem for solving the treatment efficiency in low temperatures in autumn, winter, and spring.
