High-efficiency and low-energy-consumption sewage treatment equipment

Abstract

The invention discloses high-efficiency and low-energy-consumption sewage treatment equipment. The high-efficiency and low-energy-consumption sewage treatment equipment comprises an inlet, a mixing chamber, a reaction tank and an outlet which are communicated in sequence. The mixing chamber is inclined by a certain angle, and the included angle formed between the horizontal edge and the vertical edge of the mixing chamber is 20-30 degrees. A plurality of baffle plates arranged in a staggered mode are arranged inside the mixing chamber to form a bent channel. A reaction layer is arranged inside the reaction tank. A lens layer is arranged at the lower portion of the reaction tank. The height of the lens layer is one tenth that of the reaction tank. Reflection layers are arranged on the outer surface of a tank cover and the outer surfaces of four tank walls of the reaction tank. A black light absorbing layer is arranged on the inner surface of the tank bottom. The lens layer is located above the tank bottom. The high-efficiency and low-energy-consumption sewage treatment equipment is simple and reasonable in structure, and the reaction tank absorbs solar light by means of the special structure, so that the liquid inside the reaction tank achieves circulative convection, the sewage processing efficiency of the high-efficiency and low-energy-consumption sewage treatment equipment is improved, and energy consumption of the high-efficiency and low-energy-consumption sewage treatment equipment is lowered.

Description

technical field [0001] The invention relates to a water treatment device, in particular to a sewage treatment equipment with high efficiency and low energy consumption. Background technique [0002] With the development of my country's economy and the improvement of people's living standards, people's requirements for environmental quality, especially water environment quality, are getting higher and higher. At present, domestic and foreign sewage treatment processes (domestic sewage, high-concentration sewage, industrial wastewater and sewage that are difficult to biodegrade) all use blast aeration (or other types of aeration) to increase dissolved oxygen in sewage, for example, in Blast aeration is used in domestic sewage treatment to increase the dissolved oxygen in the sewage, so that the aerobic microorganisms attached to the activated sludge or filler in the sewage can grow and reproduce, so as to decompose the sewage and purify the sewage. However, the aeration metho...
