Embodiment 1

[0047] figure 1 It is a structural schematic diagram of the present invention. figure 2 It is a structural schematic diagram of the structure of the hollow vibration conduction infusion stick of the present invention.

[0048] Such as figure 1 and figure 2 As shown, a device for solving the blockage of the medium layer in the ecological management project is characterized in that it includes: a biosurfactant solution tank 100, an outlet hose 110, an ultrasonic generator 200, an ultrasonic vibrating rod 300, a stainless steel flat bar 400, The hollow vibration conduction infusion rod structure 500 and the medium layer structure 600, the hollow vibration conduction infusion rod structure 500 is connected to the medium layer structure 600, the ultrasonic vibration rod 300 and the hollow vibration conduction infusion rod structure 500 are respectively rigidly connected through stainless steel flat bars 400, ultrasonic The generator 200 is connected to the ultrasonic vibrating...

Embodiment 2

[0072] In this embodiment, the blocked ecological treatment project is a horizontal subsurface flow artificial wetland system, which mainly treats the tail water of a certain sewage treatment plant. The length of the treatment area is 3m), and the filling layer is divided into soil and fine sand mixed layer (thickness 15cm), slag and gravel mixed layer (thickness 40cm), crushed stone layer (thickness 15cm) from top to bottom, and the slope of the bottom surface is 1%. The hydraulic load is 1.0m3 / (m2.d), continuous water inflow, and water onions are planted on the surface. Due to the large amount of suspended impurities in the influent, the system began to be partially blocked after 63 days of operation, and the water outlet was not smooth.

[0073] The system blockage solution steps and application method:

[0074] 1) In view of the fact that the system began to be partially blocked on the 63rd day, the outlet pipe was closed and water continued to flow in. According to the d...

Embodiment 3

[0082] In this example, the clogged ecological treatment project is a pilot-scale improved single-stage soil infiltration system, which mainly treats domestic sewage from rural households. The system size is 2m*0.5m*1.5m, and the filter material layer is divided into Gravel layer (thickness 20cm), soil and zeolite and cinder mixed layer (thickness 70cm), river sand and gravel mixed layer (thickness 20cm), coarse sand layer (thickness 10cm), design hydraulic load 2.0m3 / (m2.d) , intermittent water intake, wet-to-dry ratio 1:2, the system began to appear partial blockage after 125 days of operation, and the water outlet was not smooth enough.

[0083] The system blockage solution steps and application method:

[0084] 1) Turn off the water inlet, configure biosurfactant 660 with a concentration of 100mg / L, and add biosurfactant 660 as mannose erythritol lipid solution (share mannose erythritol lipid 10g, configure solution 100L) To the surface of the soil infiltration system, th...

Abstract

The invention discloses a device and method for solving medium layer blockage in ecological management engineering. The device structurally comprises a biological surfactant solution tank, an ultrasonic generator, ultrasonic vibration rods, a stainless steel flat strip, a hollow vibration conducting and liquid conveying rod structure and a medium layer structure. The hollow vibration conducting and liquid conveying rod structure is connected with the medium layer structure; the ultrasonic generator is connected with the ultrasonic vibration rods; the ultrasonic vibration rods are in rigid connection with the hollow vibration conducting and liquid conveying rod structure through the stainless steel flat strip; the biological surfactant solution tank is connected with the upper end of the hollow vibration conducting and liquid conveying rod structure through a water outlet hose. The hollow vibration conducting and liquid conveying rod structure comprises a hollow vibration conducting andliquid conveying rod, holes, a lock nut and a threaded bayonet. Compared with the prior art, the device and the method have advantages that the problem of medium layer blockage in ecological management engineering of constructed wetlands, soil infiltration treatment systems, artificial quick infiltration systems and the like at present can be effectively solved in short time, and a promising application prospect is achieved.

Description

technical field [0001] The invention relates to the technical fields of water environment treatment and sewage treatment, in particular to a method and a device for solving medium layer blockage in ecological treatment projects. Background technique [0002] Since the 1970s, with the increasingly serious and expanding surface water pollution problems at home and abroad, new ecological management technologies such as constructed wetlands (CW), soil infiltration treatment systems (MSL), and artificial rapid infiltration systems (CRI) have successively emerged. developed and widely used. These systems are widely used in river and lake water pollution, small and medium-sized towns and rural domestic sewage and agricultural non-point source pollution, urban landfill leachate, etc. Good engineering results have been achieved in pollution control and prevention projects such as disposal. In recent years, with the long-term operation and engineering practice of these projects, var...
