Biodegradation planting greenhouse

Abstract

The invention particularly discloses a biodegradation planting greenhouse which comprises a soil culture medium and a greenhouse body arranged above the soil culture medium in a covering mode. The soil culture medium comprises an inoculating layer. An impervious layer is arranged at the bottom of the inoculating layer in a paving mode. A water distribution system and a water collecting system are arranged on the upper portion and the lower portion in the inoculating layer respectively. The area of the water distribution system and the area of the water collecting system are both smaller than the area of the impervious layer. The biodegradation planting greenhouse has the advantages that cost is low, a processing technology is simple, environment pollution is lowered, crops absorb nutrients during growing, meanwhile, organic wastewater is purified, the organic wastewater is purified by the fact that the crops absorb nutrients during growing, the organic wastewater is converted into things of value, fertilization is of no need for growing crops, growing is healthy and strong, the ecological cycle of the organic wastewater is achieved, the organic wastewater is purified to reach the standard and then is discharged, and degradation and purification effect is obvious.

Description

(1) Technical field [0001] The invention particularly relates to a biodegradable planting greenhouse. (2) Background technology [0002] Organic wastewater is wastewater dominated by organic pollutants. Organic wastewater is likely to cause eutrophication of water quality and is relatively harmful. Wastewater and landfill leachate from pharmaceutical, printing and dyeing, food, chemical and other industries generally contain a large amount of organic matter such as carbohydrates, oil, protein, cellulose, etc. These organic matter exist in the sewage in a suspended or dissolved state, and through the biochemical action of microorganisms Decomposition requires oxygen consumption during the decomposition process, so it is called oxygen-consuming pollutants, which can reduce dissolved oxygen in water and affect the growth of fish and other aquatic organisms. After the dissolved oxygen in the water is exhausted, the organic matter undergoes anaerobic decomposition, producing unp...

Problems solved by technology

At present, physical methods or chemical methods are generally used to treat organic wastewater, but the effects of these two treatments are not significant. Generally, the investment is large, the process is complicated, and there is a possibility of secondary pollution.

In recent years, with the development of new separation technology, membrane separation technology has been initially applied in the treatment of organic wastewater. Although the existing organic membranes are low in cost and high in filling area, they are prone to pressure and intolerance during use. Oxidation and other shortcomings, and easy to be polluted, regeneration is difficult, the life of the membrane is generally short, the water quality of the effluent is unstable, and a large amount of organic wastewater is directly discharged to pollute the environment. Therefore, the existing treatment methods are not effective and the treatment is difficult. Very big
