Non-point source zero-pollution treatment system for rice field in ecological irrigation area

Abstract

The invention discloses a non-point source zero-pollution treatment system for a rice field in an ecological irrigation area, and relates to the technical field of non-point source pollution treatment. Comprising a water irrigation channel, a water pump is fixedly arranged at the top of the water irrigation channel, a collecting plate is movably arranged at the bottom of the water irrigation channel, a bearing plate is fixedly arranged at the top of the collecting plate, a breeding groove is formed in the top of the bearing plate, a connecting frame is fixedly arranged at the top of the bearing plate, and a movable sleeve is fixedly arranged on one side of the connecting frame; a threaded lead screw is movably arranged on the inner wall of the movable sleeve. The ridges are arranged to divide the paddy field, the ridges can consolidate the soil of the paddy field, people can walk conveniently, people can observe the treatment effect of the paddy field in the ecological irrigation area conveniently, the water inlet and the water outlet are arranged to facilitate water circulation, the accumulation degree of impurities and sludge is reduced, and the dredging and purifying capacity is high; the effect of drugs is achieved through the structure, and the zero-pollution treatment effect is good.

Description

technical field [0001] The invention relates to a non-point source zero-pollution control system for paddy fields in an ecological irrigation area, which belongs to the field of rice cultivation and watering. Background technique [0002] Rice is one of the main grain crops in China, accounting for about 40% of the total grain output. Due to the physiological characteristics of rice, a large amount of irrigation water is required throughout the growth stage. Paddy fields consume a lot of water, but their water use efficiency is low. Non-point source pollution, also known as non-point source pollution, is mainly composed of soil sediment particles, nutrients such as nitrogen and phosphorus, pesticides, and various atmospheric particles, which enter water, soil, or the atmosphere through surface runoff, soil erosion, and farmland drainage. . Its randomness, extensiveness, hysteresis, ambiguity, latentness and other characteristics increase the difficulty of corresponding re...

AI Technical Summary

Problems solved by technology

Its randomness, extensiveness, hysteresis, ambiguity, latentness and other characteristics increase the difficulty of corresponding research, governance and management policy formulation, and the pollutants such as chemical fertilizers and pesticides applied to rice fields will follow the runoff of rice fields. Or field drainage into nearby water bodies has caused serious agricultural non-point source pollution

[0003] In the existing technology, the non-point source pollution control method of rice fields in ecological irrigation areas is mainly based on drugs and supplemented by structural design, which will have a certain negative impact on the growth of rice fields, and paddy fields in irrigation areas are prone to silt accumulation and aquatic plants. The problem of debris secondary pollution of paddy fields in irrigation areas has led to people spending a lot of time on prevention and control of non-point source pollution, and the effect of water level control is not obvious, causing serious waste of water resources
