Embodiment

[0035] A high-efficiency interception system for agricultural non-point source pollution, such as Figure 1 to Figure 3 As shown, several interception channels are arranged at intervals on the agricultural irrigation ditch, and the interception channels are composed of an interception well 1, an interception control device and an inspection well 11.

[0036] On the side wall of the agricultural irrigation ditch 8, a water outlet is provided at the position corresponding to each interception well 1, and the water outlet constitutes the water inlet of the corresponding interception well 1, and the water outlet of the interception well enters the inspection well 11 through the interception opening, and the inspection well 11 water outlet It is connected with the sewage pipe 6, and the width of the retention well is 800mm.

[0037] The closure control device includes a gate 2, a headstock 3, a super-declared channel flowmeter 4 and a control unit 5. The gate 2 is arranged in the c...

Abstract

The invention discloses an efficient interception system and a control method for agricultural non-point source pollution. The efficient interception system comprises a gate for opening and closing an interception hole, a hoist for controlling the gate to be opened and closed, an ultrasonic open channel flowmeter and a control unit, wherein the ultrasonic open channel flowmeter is arranged in an interception well and is used for measuring flow of water in the interception well, and an output of the flowmeter is connected to the control unit; the output end of the control unit is connected with the hoist, to make the hoist control the gate to be opened and closed according to the flow detected by the ultrasonic open channel flowmeter. The efficient interception system is simple in structure and can realize interception according to a change of a flow difference. The efficient interception system intercepts sewage of an agricultural non-point source by a flow and time combination control mode according to the relevance between the runoff volume of an agricultural irrigation ditch and DTP concentration and the occurrence law of a concentration peak, so that more pollutants can be intercepted to the maximum extent under a condition of the same intercepted water volume. Compared with the existing interception technology, the efficient interception system is simpler, more convenient and more efficient.

Description

technical field [0001] The invention relates to the collection of agricultural sewage, in particular to an efficient interception system and control method for agricultural non-point source pollution, belonging to the technical field of sewage treatment. Background technique [0002] With the continuous deepening and progress of intensive agriculture in our country's economy, the ensuing environmental pollution problem is also becoming more and more serious. Rural non-point source pollution has become a prominent problem in my country's agricultural development. Dianchi Lake, located in the central part of Yunnan Province, is one of the largest inland freshwater lakes in my country. Kunming City is located on the shore of Dianchi Lake. The drainage area of ​​Dianchi Lake is 2920km 2 , its water resources play a vital role in Kunming's industrial and agricultural production and the lives of the people. However, due to the massive discharge of pollutants, Dianchi Lake has be...
