Domestic sewage treatment device and control method thereof

Abstract

The invention discloses a domestic sewage treatment device and a control method thereof, and relates to the technical field of domestic sewage treatment. The domestic sewage treatment device comprises a plate frame mechanism, and one side of the plate frame mechanism is provided with an inclined tube used for preliminarily filtering and processing sewage. According to the sewage treatment device, part of sewage can be reversely refluxed and re-purified through a reflux conveying pipe, so that the sewage is repeatedly adsorbed and filtered by an oxidation tank to achieve efficient purification of the sewage, the effective contact area of the sewage and an elastic filler is increased, and impurity particles and organic matters in the sewage are adsorbed and degraded; the operation steps of running the management program are reduced; manpower and material resources are saved, internal pipelines of the device are prevented from being blocked, and subsequent internal operation pressure of the device is relieved; the device plays a role of accident buffering and when a fault occurs in a subsequent treatment process, the wastewater can be temporarily stored in the device, so that a buffering effect is achieved, shutdown caused by the fact that the wastewater cannot be removed in the production process is prevented, and the situation that toxic gas harms life safety of workers is avoided.

Description

technical field [0001] The invention relates to the technical field of domestic sewage treatment, in particular to a domestic sewage treatment device and a control method thereof. Background technique [0002] Domestic sewage is the wastewater discharged in the daily life of residents, mainly from residential buildings and public buildings, such as residences, institutions, schools, hospitals, shops, public places and industrial enterprise toilets, etc. The pollutants contained in domestic sewage are mainly organic matter; Such as protein, carbohydrates, fat, urea, ammonia nitrogen, etc.; and a large number of pathogenic microorganisms, such as parasite eggs and intestinal infection viruses; Organic matter in domestic sewage reproduces in large quantities for nutrition, which can lead to the spread of infectious diseases; therefore, domestic sewage must be treated before discharge. [0003] After searching, the Chinese patent number is CN201910132666.5, which discloses a ru...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a domestic sewage treatment device and its control method to solve the problem that most of the sewage treatment devices proposed in the above background technology cannot carry out reverse reflux and repurification of part of the sewage, and cannot fully adsorb the impurity particles and organic matter inside the sewage and degradation, the operation steps of the sewage purification process of the device are cumbersome, and it is impossible to reduce the internal operating pressure of the subsequent device; it does not have a certain accident buffer function and cannot scientifically handle toxic gases
