Full-automatic sewage treatment system

Abstract

The invention discloses a full-automatic sewage treatment system. According to the full-automatic sewage treatment system, a smashing roller and an extruding roller are arranged to smash chunk waste in domestic sewage, a metal screen is arranged in a connection pipe to collect the smashed waste in a concentrated mode, and the plug phenomenon is avoided; furthermore, a primary filter screen and a secondary filter screen are arranged to block small-particle waste mixed in the sewage in a waste partition box, so that dry-wet separation of the sewage is achieved; by means of an aeration machine, pollutants in the sewage can form large suspension solid flocculation, and the flocculation can float on the liquid surface under the floating action of bubble groups to form scum; a third motor is started to drive a sweeping roller to rotate to guide the scum into a sundry cavity, so that the amount of pollutants in the sewage drained out from a water draining opening is remarkably reduced, and convenience is brought to following treatment work; the whole process is automatically controlled by a single chip microcomputer, a timer and a sensor are utilized to finish action of all functional components, manual operation is avoided, an intelligence degree is high, and convenience in use is achieved.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a fully automatic sewage treatment system. Background technique [0002] Sewage produced in the process of human life is one of the main sources of water pollution. It is mainly feces and washing sewage. Domestic sewage contains a large amount of organic matter, such as cellulose, starch, sugar and fat protein; it also often contains pathogenic bacteria, viruses and parasite eggs; inorganic salts such as chloride, sulfate and phosphate , bicarbonate and sodium, potassium, calcium, magnesium, etc. The general feature is high nitrogen, sulfur and phosphorus content, and under the action of anaerobic bacteria, it is easy to generate odorous substances. [0003] During the treatment of domestic sewage, due to the many impurities contained in the sewage, the treatment effect is likely to be unsatisfactory, and the sewage needs to be separated from the dry and wet. Usually, the centri...

Problems solved by technology

[0003] During the treatment of domestic sewage, due to the large amount of impurities contained in the sewage, the treatment effect is likely to be unsatisfactory. It is necessary to separate the dry and wet sewage from the sewage. Usually, a centrifuge is used to separate the dry and wet sewage, but some of the domestic sewage The debris is large in size, which can easily cause equipment blockage
