Sewage treatment system

Abstract

The invention discloses a sewage treatment system comprising a biofiltration bed and an ecological compound bed which are connected through a pipeline, wherein the biofiltration bed is a cylindrical tank body with two spherical ends; the biofiltration bed is sequentially partitioned into a sewage tank, a regulating tank, an anaerobic tank, an aerobic tank, a sedimentation tank and a clear water tank; the regulating tank is internally provided with an air lift pump connected with a lift pipeline and used for uniformly delivering sewage; the air lift pump provides kinetic energy through an air pump connected with a solar cell panel; and the sedimentation tank is internally provided with a guide cylinder on which a guide pipeline is arranged, S-shaped filter beds are distributed at two sides of the guide cylinder, and a reflecting plate is distributed below the guide cylinder. According to the sewage treatment system, the traditional water pump is replaced with the air pump, and the solar energy is converted into electric energy through the solar cell panel, so that the system can realize low-noise sewage treatment under the condition that the solar energy is sufficient; in addition, due to the arrangement of the guide cylinder, the reflecting plate located below the guide cylinder and the S-shaped filter beds distributed at two sides of the guide cylinder, the sewage is more sufficiently filtered.

Description

technical field [0001] The invention relates to a small domestic sewage treatment process, in particular to a sewage treatment system. Background technique [0002] Domestic sewage mainly refers to washing wastewater and domestic wastewater. Domestic sewage contains a large amount of organic matter, germs, and bacteria. If it is discharged directly without treatment, it will cause serious pollution to the environment. With the continuous improvement of people's living standards, environmental awareness Gradually improving, people have higher and higher requirements for domestic sewage treatment. At present, the main methods of domestic sewage are anaerobic treatment and aerobic treatment in reinforced concrete pools or carbon steel integrated equipment, which has the disadvantages of high noise, high energy consumption, and the treatment The problem of poor effect and poor landscape effect is difficult to popularize and apply. Contents of the invention [0003] An object ...
