Buried sewage multi-stage treatment device for landscape garden

Abstract

The invention discloses a buried sewage multi-stage treatment device for a landscape garden. The device comprises a sewage reservoir, a sedimentation degradation mechanism is installed at the bottom of the sewage reservoir, a combined purification mechanism is arranged outside the sewage reservoir, a self-regulating power mechanism is arranged outside the combined purification mechanism, the sedimentation degradation mechanism comprises sedimentation cylinders installed on both sides of the bottom of the sewage reservoir, the sewage reservoir is connected to the sedimentation cylinders throughconnecting grooves, the combined purification mechanism comprises a reflow pipe connected to the top of a reflow bucket, the top of the reflow pipe is connected to a treatment tube, two filter sievesare arranged in the treatment tube, the two filter sieves are fixedly connected through a bonding base, a plurality of glass tubes are arranged inside the bonding base, and an ultraviolet lamp is installed inside the glass tube. Through sedimentation, multi-stage filtration and sterilization, the sewage is purified so that the environmental pollution is reduced and the sewage utilization rate isimproved. The buried sewage multi-stage treatment device is powered by solar energy so that the concept of environmental protection is realized.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an underground multi-stage sewage treatment device for landscape gardens. Background technique [0002] Sewage, usually refers to certain polluted discharge water from domestic and production. Sewage mainly includes domestic sewage, industrial wastewater and initial rainwater. The main pollutants of sewage include pathogen pollutants, oxygen-consuming pollutants, plant nutrients and toxic pollutants. [0003] Water pollution is water that reduces or loses the use value of water caused by harmful chemicals and pollutes the environment. Acids, alkalis, oxidants, and compounds such as copper, cadmium, mercury, and arsenic in sewage, organic poisons such as benzene, dichloroethane, and ethylene glycol, will kill aquatic organisms and affect drinking water sources and scenic spots. When the organic matter in the sewage is decomposed by microorganisms, the oxygen in the wate...

AI Technical Summary

Problems solved by technology

[0005] (1) General sewage treatment devices use external power, which causes waste of electric energy while realizing sewage treatment, increases pollution to a certain extent, and does not conform to the concept of green environmental protection;

[0006] (2) Moreover, the general sewage treatment device cannot process the impurities in the water step by step, which often leads to the chaotic impurities in the treated sewage which are difficult to deal with, and are generally treated by a single filtration method, which is prone to insufficient purification treatment.
