Rural breeding wastewater treatment and plant purification three-dimensional system

Abstract

The invention discloses a rural breeding wastewater treatment and plant purification three-dimensional system. The system comprises a purification device, the purification device comprises a dirt intercepting pond, a planting pond and an odor removing pond, the dirt intercepting pond, the planting pond and the odor removing pond are arrayed in a stair form from high to low, and the lower ends of the side walls of the dirt intercepting pond, the planting pond and the odor removing pond are fixedly communicated with drainage pipes; a collection frame is movably placed on the bottom surface in the dirt intercepting pond, a first dirt intercepting rack and a second dirt intercepting rack are movably inserted in the portion, above the collection frame, of the inner wall of the dirt interceptingpond, and an active sludge layer is flat laid on the bottom surface in the planting pond; an active carbon layer is flat laid on the bottom surface in the odor removing pond, the first dirt intercepting rack and the second dirt intercepting rack are utilized for intercepting large floating objects in wastewater, and duckweed and the active sludge layer flat laid at the bottom in the planting pondare utilized for removing organic pollutants in the wastewater; the active carbon layer flat laid on the bottom surface in the odor removing pond is utilized for removing an odor of the wastewater, the treated wastewater is used for irrigation and the like, and water recycling is achieved.

Description

technical field [0001] The invention relates to the technical field of purification of aquaculture wastewater, in particular to a three-dimensional plant purification system for treating rural aquaculture wastewater. Background technique [0002] Intensive livestock breeding has important practical significance in increasing farmers' income and promoting rural economic development, but the breeding wastewater not only contains high total nitrogen, total phosphorus, ammonia nitrogen, nitrate nitrogen and other pollutants and a large amount of suspended solids, but also contains Escherichia coli, roundworm eggs and other harmful pathogens. If the aquaculture wastewater is discharged directly without treatment, it will pollute surface water, soil and groundwater, thereby affecting the safety of drinking water in rural areas; and various harmful pathogens will also easily deteriorate the living and ecological environment, leading to increased morbidity and mortality of livestock...

Problems solved by technology

If the aquaculture wastewater is discharged directly without treatment, it will pollute surface water, soil and groundwater, thereby affecting the safety of drinking water in rural areas; and various harmful pathogens will also easily deteriorate the living and ecological environment, leading to increased morbidity and mortality of livestock and poultry, and even endangering At the same time, due to the use of commercial feed with a large amount of additives in intensive farming, the excrement of poultry and livestock contains high levels of heavy metals such as cadmium, lead, copper, zinc, etc., which can easily lead to the accumulation and pollution of heavy metals in soil and water. Environmentally friendly aquaculture wastewater treatment devices on the market are inefficient and usually consume a lot of energy, increasing the cost of wastewater treatment, and the treatment procedures of ordinary environmentally friendly aquaculture wastewater treatment devices are relatively simple, resulting in treatment effects that cannot meet national standards. As a result, it cannot meet people's needs. Therefore, we propose a three-dimensional plant purification system for rural aquaculture wastewater treatment to solve the above problems.
