Embodiment

[0028]Embodiment: Under natural conditions, directly transplant the collected G. chinensis seedlings into a rubber bucket of 29cm*26cm*32cm, with water pipes arranged at the bottom, and gravels with a thickness of 5cm and a diameter of 2-5cm from bottom to top. Layer, 10cm thick coarse sand layer, 10cm thick (approximately 8kg) soil layer, tap water is stable for 15 days. After the plants are stabilized, the wastewater from livestock and poultry breeding is regularly irrigated, and water samples are collected and the water quality of the effluent is measured (the hydraulic retention time is set to 7 days). The amount of water in the pot test was determined by the estimation formula (1) recommended by Reed:

[0029] (1)

[0030] In the formula: Q——design wastewater flow rate, m 3 / d;

[0031] F——land area occupied by constructed wetland, hm 2 ;

[0032] K—coefficient, 6.57×10 -3 .

[0033] According to calculation, the treated water volume of the pot experiment is...

Abstract

The invention discloses an application of begonia fimbristipula hance in treating livestock and poultry raising wastewater. The begonia fimbristipula hance is planted in an environment polluted by the livestock and poultry raising wastewater and is used for purifying the livestock and poultry raising wastewater. The invention provides a novel plant resource for treating wastewater, especially the wastewater generated in the process of raising the livestock and poultry. The plant resource has the advantages of low plant cost and good treatment effect, and dose not cause no secondary pollution on a water body.

Description

technical field [0001] The invention relates to the technical field of natural biodegradation of wastewater from livestock and poultry breeding, in particular to the application of artificial wetland plants in treating wastewater from livestock and poultry breeding. Background technique [0002] The pollution of livestock and poultry breeding wastewater is long-term and irreversible. Its pollution is characterized by high suspended solids, high organic matter and high ammonia nitrogen, strong biodegradability and strong odor. [0003] The livestock and poultry industry is an important part of my country's agriculture and rural economy, and it is also one of the main causes of non-point source pollution in my country's rural areas. The environmental pollution caused by the vigorous development of the livestock and poultry industry is becoming more and more serious, which not only affects economic development, but also Endangering ecological security has become a social issue o...
