Embodiment 1

[0030] figure 1 It is Embodiment 1 of the present invention, that is, a schematic diagram of the general plan of hydraulic control of a representative water plant constructed wetland. figure 2 and image 3 is the local refinement in Example 1. From figure 1 It can be seen in the figure that the source water or sewage 1 first passes through the water inlet interception and control system 8, then passes through the water inlet gate 2, flows to the front pond 15, and then passes through the wetland plant bed-trench system 9, the buffer pond 16, and the pumping station in sequence 5. Oxygenation ponds 17, one or more wetland plant bed-ditch systems 9, one or more back ponds 18, become waterworks or receiving water bodies 19.

[0031] In this embodiment, after the water flow enters the front pond 15, due to the sudden expansion of the water passing area, the flow rate of the water flow decreases rapidly, which plays the role of sand settling and buffering, and the suspended sol...

Embodiment 2

[0044] Figure 4 It is the schematic diagram of interception of water inlet and composite probe control of the constructed wetland. A semi-hanging enclosure 20 is set 10m in front of the water inlet 2, which is fixed and suspended in front of the water inlet to prevent water hyacinth, duckweed and a large amount of floating garbage from entering the wetland. At the same time, a composite probe monitoring box 21 is installed between the semi-hanging enclosure 20 and the water inlet sluice 2. The functions of the composite probe include in-situ monitoring of water level and water quality and remote signal transmission to automatically monitor and identify the water quality of the wetland inlet, including water level, Water quality indicators such as turbidity, dissolved oxygen, and ammonia nitrogen, especially when encountering irregular rainstorms in the river network area, a large number of hidden pollution sources are instantly washed into the river, and the water level and p...

Abstract

The invention provides an artificial wetland waterpower flow path driving system and an artificial wetland waterpower flow path driving method, and relates to a composite artificial wetland waterpower control method. Water project structures including gates, pump station systems and water project micro-structures are reasonably arranged along a waterpower path in an artificial wetland; through combined control to the water project structures, the wetland waterpower path driving is realized, and different flow states are established in different parts of the wetland; by controlling the opening and closure number and time of water pumps as well as the opening and closure time and the opening degrees of the gates, the wetland waterpower control is realized, including the water level rising and descending, water quantity distribution and waterpower staying time of the wetland; and by optimizing the waterpower control mode, the water quality purification function of the wetland is improved. Aiming at the key section of improving the artificial wetland water quality purification efficiency by optimizing the waterpower control, the invention provides a technique for coupling improvement of artificial wetland waterpower control and water quality purification function.

Description

technical field [0001] The invention relates to a hydraulic process driving system and method of a constructed wetland, and also relates to a method for systematically improving the water quality purification function of a constructed wetland by optimizing hydraulic control. Background technique [0002] Constructed wetland technology has been widely used at home and abroad because of its various forms, high treatment rate, and strong adaptability. It has become an effective way for developed countries and regions to explore and solve the problems of water pollution and water shortage. The process-driven mode and hydraulic control mode are the key links to ensure its efficient operation. Contents of the invention [0003] 1. Technical problems to be solved [0004] In order to realize the efficient operation of constructed wetlands, it is necessary to overcome the single form of water flow in constructed wetlands and the lack of driving of the hydraulic process in the sec...
