Biological treatment device for river pollutants

Abstract

The invention discloses a biological treatment device for river pollutants. The device comprises: a floating box, solar cell panels, a first duct and a second duct, a positive electrode and a negativeelectrode, a water pump, a spray head, biological filler, a burner nozzle, a temperature controlled igniter and a heating pipe. The device provided by the invention utilizes electrolysis produced oxygen to oxygenate river water and promote microbial growth and aerobic degradation, and achieves effective biological treatment of river pollutants. At the same time, the device also utilizes electrolysis produced hydrogen combustion to keep the filler temperature so as to maintain the activity of microorganisms in a low temperature environment, and realizes effective biological treatment of riverpollutants in a low temperature environment. The biological treatment device provided by the invention has the advantages of no need for additional power unit, low running cost and simple maintenance,and is suitable for popularization and application.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment in environmental protection, and in particular relates to a biological treatment device for river pollutants. Background technique [0002] In recent years, with the growth of population and rapid economic development, more and more pollutants have been discharged into urban rivers, and urban rivers have been seriously polluted. Urban river pollution seriously affects people's life and health, and restricts the sustainable development of our country's social economy. Therefore, while developing the economy, we should actively study the river pollution control technology suitable for the economic development stage of our country. [0003] Bioremediation refers to the use of biological life and metabolism activities in polluted water bodies to degrade organic pollutants and purify the water environment, so as to restore the water body to its pre-polluted state and restore its use value.

Problems solved by technology

Therefore, in cold regions, such as northern China, due to temperature restrictions in winter, it is difficult to effectively treat pollutants, resulting in deterioration of river water quality in winter

[0005] The methods used by researchers at home and abroad to solve the low efficiency of low-temperature sewage treatment include increasing the residence time of sewage in the project, building some structures indoors, or taking measures such as heat preservation and temperature rise to ensure that the effluent of sewage treatment in winter meets the standard

However, these measures not only increase project investment, energy consumption and operating costs, but also find that the effect of sewage treatment is still difficult to guarantee in practice
