Embodiment 1

[0026] This embodiment is the application of ground fruit to treat livestock and poultry breeding biogas slurry, and the specific application method is as follows:

[0027] 1. Construction of Constructed Wetland System

[0028] The size of the wetland system is 100cm×45cm×75cm (L×W×H); it includes the water distribution pipes installed on the top of the wetland system, and the bottom of the wetland system is the water collection tank and water outlet. Gravel layer, slag layer and sand layer are laid sequentially from the sump to the top. The constructed wetland bed is characterized in that: the inside of the wetland bed is composed of wetland filling matrix and shale hollow bricks, and there is a water collection tank at the bottom of the wetland system to collect waste water treated by the wetland system.

[0029] In order to enhance the oxygen supply capacity inside the wetland system, thereby improving the purification effect of organic matter in wastewater, shale hollow b...

Abstract

The invention discloses application of ficus tikoua in purification of livestock and poultry cultivation biogas slurries. The ficus tikoua is planted in an environment polluted by the livestock and poultry cultivation biogas slurries, the absorption effect of the ficus tikoua on pollution matters such as NH4+-N, TN, TP, CODcr in the livestock and poultry cultivation biogas slurries is sufficiently used, the ficus tikoua has dogged life force, can be directly planted, needs no special management, has the perennial characteristic, and can perpetually solve pollution problems of the livestock and poultry cultivation biogas slurries. The application has the advantages of being small in investment, good in effect, simple in operation, easy to apply and the like, and can guarantee winter purification effect of a wet land system. Harvested ficus tikoua can be used for medicines, the major functions of the ficus tikoua is chronic bronchitis, rheumatism physique ache, diarrhea, dysentery, mammitis, edema, abnormal menstruation, postpartum animal spirits ache, venomous snake bite and the like. The ficus tikoua is used for processing waste water, environmental protection and economic construction are combined, an operation mode of depending on government investment all the year of the traditional ecological engineering is expected to change, and the application of the ficus tikoua has profound and lasting significants.

Description

technical field [0001] The invention relates to the field of livestock and poultry breeding biogas slurry treatment, in particular to an application of artificial wetland plants to purify livestock and poultry breeding biogas slurry. Background technique [0002] In recent years, with the rapid development of the large-scale and intensive livestock and poultry breeding industry, the environmental pollution caused by the livestock breeding industry has become increasingly serious, and its impact on rural drinking water safety, irrigation water, soil, agricultural products and air quality and rural The living environment poses a great threat. Anaerobic digestion technology has been widely used in the bioenergy development and pollution control of livestock and poultry wastewater, which can effectively suppress the primary pollution of livestock and poultry wastewater; however, the biogas slurry of many large-scale farms is directly discharged, resulting in Serious secondary p...
