Small integrated purification device for sewage and air treatment

Abstract

The invention discloses a small integrated purification device for sewage and air treatment.A water circulation portion at the bottom, a plant wall portion and an air purification portion in the middle and a control box at the top are stacked into a whole; the water circulation portion is composed by sequentially connecting an anaerobic sewage decomposition tank, a subsurface wetland purification layer and a clean water tank; the plant wall portion is arranged over the anaerobic sewage decomposition tank and comprises plants, a wall body frame and plant planting pits and plant irrigation distribution pipes which are laid on the wall body frame, and a wind screen and an air filter core are arranged in the plant wall; the control box is arranged at the top end of the plant wall portion and provided with plant light supplementing devices, and when illumination is deficiency, the light supplementing devices supply illumination.The small integrated purification device has the dual effects of domestic sewage treatment and indoor air purification, not only reasonably utilizes water resources, but also reduces the plant maintenance and management cost and can improve the indoor air purification effect.

Description

technical field [0001] The invention relates to a plant wall integrating domestic sewage treatment and air purification. Background technique [0002] People spend more than 80% of their lives indoors, and the quality of indoor air has a direct impact on people's health. However, with the extensive use of modern building decoration materials and the popularization and long-term use of air-conditioning devices, coupled with the aggravation of environmental pollution, especially air pollution, indoor air generally cannot meet indoor quality standards. In order to improve indoor air quality, reduce the concentration of indoor air pollutants (such as formaldehyde, benzene and benzene series, TVOC, ammonia, radon and PM2.5), improve the indoor living environment, and improve people's quality of life, indoor air purification is a common The technical means used. Among them, the indoor plant green wall is an environmentally friendly treatment technology. This technology is to pla...

Problems solved by technology

However, this technology does not clearly disclose its specific structure. From the known structure, there are deficiencies such as plant nutrition needs to be supplemented with nutrient solution separately, and plant irrigation water must be strictly filtered, otherwise it will easily block the irrigation system and cause plants to die due to lack of water.

[0004] Of course, the technology disclosed by the existing plant wall is not limited to the ones listed above. The applicant has also read more technologies about the design of the plant wall. According to the conclusion of the applicant, the main shortcomings of the existing plant wall technology are: 1. The existing plants The wall air purifier does not have the function of domestic sewage purification; 2. The water and nutrients required by the plant wall plants need additional supply, which increases maintenance costs; 3. The plant irrigation system is easy to block; 4. The plant configuration is mostly shallow-rooted terrestrial drought-tolerant plants 5. The long-term effect of air purification is not good
