Continuous laminar flow conversion oxygenation and bioaugmentation integrated device for black and odorous water treatment

Abstract

The invention discloses a continuous laminar flow conversion oxygenation and biological enhancement integrated device for black stinking water treatment. The device comprises a biochemical reactor, an air pump, a solar power generation system and an artificial biological floating island which are sequentially connected, wherein an aeration device is arranged in the biochemical reactor and is connected with the air pump; the air pump is connected with the solar power generation system; the biochemical reactor is suspended in a water body below the artificial biological floating island; the solar power generation system comprises a solar cell panel; the artificial biological floating island comprises a UPVC frame; a nylon net is laid on the top of the UPVC frame; aquatic plants are planted on the surface of the nylon net; a first base plate and a second base plate are arranged on the nylon net; a waterproof box is fixed on the first base plate; and the solar cell panel is fixed on the second base plate. The device can be used for treatment of urban black stinking water and can achieve the aims of effectively removing pollutants in water, increasing the oxygen content in the water body and inhibiting water eutrophication; meanwhile, the solar power generation system serves as a power supply of the air pump, so that automatic and stable operation of the system is guaranteed, and the investment and operating cost can be saved.

Description

technical field [0001] The invention belongs to the technical field of restoration of polluted water bodies, and in particular relates to a continuous laminar flow conversion oxygenation and bioaugmentation integrated device for black and odorous water treatment. Background technique [0002] Urban black and odorous water bodies mainly appear in urban built-up areas, showing uncomfortable colors or emitting unpleasant odors. In recent decades, the scope and degree of black and odorous water bodies have been increasing, becoming one of the environmental problems that the government and the public are generally concerned about. The main causes of black and odorous water bodies are hypoxia and eutrophication. The technologies applied to the treatment of black and odorous water bodies mainly include source control and sewage interception technology (sewage interception and storage, non-point source control), internal source treatment technology (garbage cleaning, biological res...

Problems solved by technology

However, the application of these technologies has certain limiting factors, such as large engineering volume, high cost, continuous operation and maintenance, power consumption, and the risk of secondary pollution, etc.

[0003] At present, the main technology used for water pollution control is mixed oxygenation, and the aeration equipment is driven by electricity on the shore, but the energy utilization efficiency is low. areas where it is difficult to apply
