Application of valerian in treating livestock breeding wastewater

Abstract

The invention discloses a method for treating livestock breeding wastewater, which is realized by planting valerian in the environment polluted by livestock breeding wastewater. The method uses the adsorption and removing characteristics of pollutants such as total nitrogen, total phosphorus, ammonian and the like in the livestock breeding wastewater, and plants the valerian in the environment polluted by livestock breeding wastewater to adsorb and remove the pollutants of the total nitrogen, the total phosphorus, the ammonian and the like in the livestock breeding wastewater; the valerian has vigorous vitality and does not need carry out special treatment in the grow process, thereby the cost and the running expense are low, the effect is good and the maneuverability is strong; and meanwhile, the valerian has higher medical value, can treat unease, dyspepsia, lumbago, cooling and the like; certain components have functions of reducing the blood pressure on animals; and total alkaloids of the valerian have a plurality of functions of antibiosis, antidiuresis and the like.

Description

technical field [0001] The invention belongs to the technical field of natural biodegradation treatment of livestock and poultry breeding wastewater, and in particular relates to the application of valerian in treating livestock and poultry breeding wastewater. 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 of wid...

AI Technical Summary

Problems solved by technology

[0008] The inventor found that valerian can effectively reduce ammonia nitrogen, total phosphorus, total nitrogen, COD Cr Therefore, the purpose of the present invention is to address the problem of insufficient plant resources that can be used to treat livestock and poultry breeding wastewater pollution in the above-mentioned prior art, and provide A new plant resource that can be used to treat livestock and poultry breeding wastewater pollution; the plant resource provided by the invention has the characteristics of low planting cost, low operating cost, good effect, and strong operability
