Domestic sewage material filtration device

Abstract

The invention discloses a domestic sewage material filtration device, belonging to the field of domestic sewage treatment. The domestic sewage material filtration device comprises a filter cylinder, abuffer tank, a precipitation tank, an adsorption tank, a deoiling tank and a biochemical filter tank which are sequentially connected; a water through opening is formed in the lower part of one sideof the filter cylinder, a sweeping scraper is arranged inside the filter cylinder, a free end of the sweeping scraper extends to the internal wall of the filter cylinder; a discharge opening connectedwith a sundry collection tank is arranged at the low part of a side, opposite to the water through opening, of the filter cylinder, and a filterer screen layer is arranged inside the sundry collection tank; a rotating shaft driven by a high-speed motor is arranged inside the adsorption tank, a spirally-surrounded spiral slideway is fixed on the rotating shaft, the external side edge of the spiralslideway is attached to the internal wall of the adsorption tank, a gap in the adsorption box is uniformly filled with activated carbon, a high temperature steam generation tank is connected to the bottom of the adsorption tank corresponding to one side of the lower end of the spiral slideway. The domestic sewage filter material device has an impurity removal function for domestic sewage, especially has a relatively high efficient function for preliminary filtration and adsorption filtration on sewage, and has relatively good treatment effects.

Description

technical field [0001] The invention relates to the field of domestic sewage treatment, in particular to a domestic sewage filter material device. Background technique [0002] In the prior art, domestic sewage refers to the washing water discharged by residents in daily life, mainly including kitchen sewage and bathroom sewage. In fact, only a small part of sewage has been treated, and most of it is directly discharged into rivers without treatment. , the components of pollutants in sewage are relatively complex, and it is difficult for any treatment method to achieve the purpose of complete purification, but it often requires several methods to form a treatment system to meet the treatment requirements. According to the different treatment degrees, the sewage treatment system can be divided into Primary processing, secondary processing and advanced processing. Primary treatment only removes suspended solids in sewage, mainly physical methods, and the treated sewage genera...

Problems solved by technology

However, it has the following disadvantages: in its pretreatment, only the grid installed in the container is used for preliminary filtration, and the collection of filtered debris is relatively inconvenient, and it is very likely that debris will adhere to or get stuck on the grid and affect the follow-up process. The filtering effect is very good, and the collected sundries may contain more water; the later filtering mechanism uses biological and biochemical filter materials, and its filtering function is not comprehensive enough, and the treated sewage may contain biological and chemical methods Organic pollutants that are difficult to remove, etc.
