Description

Sanitary treatment equipment for domestic sewage

Technical Field

The utility model relates to a sanitary treatment equipment for domestic sewage.

Background

The sewage generated in the human life process is one of the main pollution sources of the water body. The main characteristics are that various detergents, sewage, garbage, excrement and the like used in urban life are nontoxic inorganic salts, and domestic sewage contains more nitrogen, phosphorus and sulfur and more pathogenic bacteria. Feces and wash sewage. The daily discharge of domestic sewage of each person in a city is 150-400L, and the quantity of the domestic sewage is closely related to the living standard.

At present, septic tanks or excrement collectors are mainly used for simple treatment in families, and generally, sewage discharged by the septic tanks or the excrement collectors basically does not accord with national discharge standards and needs to be treated again by a special sewage treatment plant. In areas where there is no sewage treatment plant, such as remote rural areas, trains, ships or airplanes, the discharged sewage can flow directly to the surface, invade the ground or sea water, and cause serious pollution to the human groundwater source.

In order to solve the problems, the Chinese patent with the publication number of CN 203829788U discloses a sanitary sewage treatment device, which comprises a crushing layer, a coarse filtering layer, a first filtering layer, a second filtering layer, a discharge layer, an infusion layer, a recycling layer and a water pump, wherein a crusher is arranged in the crushing layer, a sewage discharge port connected with a toilet bowl is arranged at the bottom of the crushing layer, a fourth filtering net and a first plant filtering net are sequentially arranged in the middle of the second filtering layer from bottom to top, a discharge port is arranged on the discharge layer, the discharge layer is communicated with the infusion layer through an automatic single-door, a second plant filtering net is arranged between the automatic single-door and the infusion layer, a water inlet of the water pump is connected with the recycling layer, and a water outlet of the water pump is connected with the toilet bowl for flushing the water.

After long-term practice, we have found that the above processor suffers from the following problems:

firstly, when the filth acceleration rate is too fast, smash the layer and can't in time smash the filth, cause the great filth of volume to block up filter screen one, hinder rivers and get into coarse filtration layer.

Second, under the action of gravity, the large granule filth that is detained in coarse filtration layer and filter layer one can deposit in coarse filtration layer and filter layer one bottom, uses after the certain time, and the deposit is more and more, can progressively block up filter screen two between coarse filtration layer and the filter layer one, filter screen three between filter layer one and the filter layer two, leads to the circulation passageway littleer and more, influences sewage treatment efficiency, must clear up on time. When the installation space is limited, the coarse filter layer, the first filter layer and the second filter layer can only be compactly arranged, the cleaning brush can only be held by hand for manual cleaning, the cleaning speed is low, the labor intensity is high, time and labor are wasted, and the domestic sewage sanitation processor is not beneficial to popularization and application.
