Ecological drainage and storage yard comprehensive utilization method for dredger fill sludge storage yard

Abstract

The invention relates to an ecological drainage and storage yard comprehensive utilization method for a dredger fill sludge storage yard. An ecological hard shell layer is manufactured on the surfacelayer of the sludge storage yard, and a drainage-tensile straw nutrient bag with drainage capacity, certain strength and capability of providing oxygen and nutrients for the growth of loaches or finless eels at the same time is driven into sludge at the lower part of the hard shell layer, so that the purposes of feeding the loaches or the finless eels at the deep sludge of the storage yard, accelerating deep sludge drainage, improving the bearing capacity of the surface hard shell layer and the like are achieved; and meanwhile, agglomeration of sludge particles around a drainage body is accelerated by utilizing organic matters existing in excreta and the like in the growth process of the loaches or the finless eels, drainage channels in the sludge around the drainage body are increased byutilizing the drilling characteristic of the loaches or the finless eels in the sludge in the living process, and sludge drainage is further accelerated.

Description

technical field [0001] The invention relates to a method for ecological drainage and comprehensive utilization of a dredged mud storage yard, which belongs to the field of dredging mud treatment. Background technique [0002] Every year in my country, a large number of rivers are dredged, resulting in a large amount of dredging silt. At present, mud dumps are generally set up on the waste land on both sides of the river, and the dredged fluid dredged silt is blown and filled into the mud dump for disposal. Due to the high moisture content of the dredged silt, it cannot be directly used as a construction project. In addition, many storage yards are requisitioned agricultural land. Therefore, a common practice is to carry out ecological reinforcement treatment on the surface silt of the silt yard to form a hard crust, which can be used for plant cultivation by masters, while the bottom of the hard crust is still fluid silt, which requires a long period of time. Consolidation...

Problems solved by technology

Although report utilizes traditional ditching technology in some existing technologies, the feeding depth of loach reaches 1.5 meters, but ditching depth is limited, and depth is darker, and the soil body on both sides of ditch collapses easily, causes ditch and can not form; In good soft clay, the depth of the trench is difficult to exceed 2 meters, and for the silt foundation, the trench generally does not exceed 0.5m. If it is newly dredged silt, it is in a fluid state, and it is basically impossible to form a trench

In addition, the excavation of the trench will also occupy the surface area. If the surface is planted, the planting area will be greatly reduced.
