Problems solved by technology

[0003] In terms of sewage treatment, especially rural household sewage, since there is no fixed discharge outlet, the discharge is relatively scattered, and some have no drainage system, which not only makes the sewage flow horizontally, but also seeps into the ground for a long time, causing the groundwater to contain nitrogen, phosphorus, and sulfur. There are many diseases and bacteria, and the water quality is deteriorating. However, the traditional sewage treatment process has disadvantages such as high treatment cost, large floor area, low removal effect of nitrogen and phosphorus compounds, and sludge generation.
Moreover, after the treated effluent is discharged into the water body, it will still cause environmental problems such as "eutrophication"
Relying solely on traditional sewage treatment methods is still difficult to fundamentally solve the problem of water pollution under the current situation in our country, and can only delay its development trend.

Embodiment 1

[0024] A specific ecological green wall construction includes three unit systems: 1. Ecological wall system 2. Green wall plant infiltration system and 3. Internal drainage system.

[0025] The basic material of ecological wall system 1 is ecological wall brick.

[0026] The basic materials of ecological wall bricks are cement, fly ash, polyether polycarboxylate superplasticizer (concrete surface enhancer), construction waste, garden trimmings, zeolite, and activated carbon.

[0027] Specific preparation method: Mix cement, construction waste, garden trimmings, zeolite, and activated carbon according to various ingredient ratios for 30-45 seconds, add water reducing agent, and then stir for 30-45 seconds, install the mold, and use the designed sewage before installing the membrane Go design holes, weep holes, hydrostatic molding. After forming, test the compressive strength, water permeability and water retention of the brick body. Among them, the water-cement ratio is 0.08-...

Abstract

The invention discloses an ecological green wall for sewage treatment. The ecological green wall comprises an ecological wall system, a green wall plant infiltration system and an internal drainage system. The cost of an ecological green wall of the present invention is relatively cheap, and the operability is strong, which can maximize the ecological function of solid waste, and use it to treat and discharge scattered rural domestic sewage, which can not only reduce water pollution, but also achieve resource utilization It has very important practical significance for the treatment of rural domestic sewage.

Description

technical field [0001] The invention relates to the field of green environmental protection, in particular to an ecological green wall used for purifying domestic sewage in rural areas. Background technique [0002] With the further development of my country's economy and society, solid waste and water pollution have become the main factors of my country's environmental pollution. Under the dual pressure of water shortage and increasingly serious environmental pollution, the resource utilization of solid waste and wastewater purification treatment have received extensive attention. Traditional solid waste treatment usually adopts incineration, landfill, solidification methods, etc., which will not only cause pollution to a certain extent, but also cause waste of resources. It is imperative to seek resource utilization of solid waste. At present, the utilization of solid waste includes ecological coverage, composting fermentation, biochar, and plate production. [0003] In ...
