Embodiment 1

[0027] This embodiment is the application of broken rice chestnuts in the treatment of livestock and poultry breeding wastewater, and the specific application method is as follows:

[0028] Under natural conditions, the collected seedlings are directly transplanted into a rubber barrel of 24cm×24cm×33cm, with a water pipe at the bottom, and gravel with a diameter of about 2-5cm at the bottom, with a thickness of 5cm, and the thickness of the upper layer The sand layer is 10cm, and finally a soil layer with a thickness of 10cm (approximately 8kg) is laid on the sand layer, and the 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 (wherein the optimal hydraulic retention time is 5 days). The water inflow in the pot test was determined according to the following method, which was obtained from the estimation f...

Abstract

The invention discloses application of cardamine hirsute in treating livestock and poultry cultivation wastewater by planting the cardamine hirsute in the contaminated environment of the livestock and poultry cultivation wastewater. By fully utilizing the adsorption and removing characteristics of the cardamine hirsute on ammonia nitrogen, total phosphorus, total nitrogen, CODCr and other contaminants in the livestock and poultry cultivation wastewater, the cardamine hirsute is planted in the livestock and poultry cultivation wastewater to absorb the ammonia nitrogen, the total phosphorus, the total nitrogen, the CODCr and other contaminants accumulated in the wastewater, thereby reducing the content of the contaminants in the wastewater, and purifying the livestock and poultry cultivation wastewater; the application has the characteristics of low cost, low operation expense, good effect, strong maneuverability and the like, develops a new plant resource variety for the treatment of the livestock and poultry cultivation wastewater, brings new progress and development space for deep development of treating the livestock and poultry cultivation wastewater by constructed wetland plant, fully and reasonably utilizes resources and achieves multifunction.

Description

technical field [0001] The invention belongs to the technical field of waste water purification by artificial wetland plants, and in particular relates to the application of broken rice chestnuts in treating livestock and poultry breeding waste water. 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 water 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 endangers Ecological security has become a social issue of widespread concern. The f...
