摘要： The invention relates to a refuse landfill impervious system capable of prolonging breakdown time of leachate and a manufacturing method thereof. The system comprises a leachate collection and drainage layer, a first HDPE (high-density polyethylene) geomembrane impervious layer, a clay layer and a groundwater collection and drainage layer which are sequentially stacked from top to bottom. The clay layer is composed of a lower clay layer, a middle clay layer and an upper clay layer which are sequentially arranged, wherein the middle clay layer is filled with a medium-fine sand layer laid with sands of particle sizes ranging from 0.1 mm to 0.5 mm and of water contents ‰¤ 3%, wherein the saturated permeability coefficient of the medium-fine sand layer varies from 1×10 -5 to 1×10 -3 cm/s. Therefore, breakdown time of the leachate can be greatly prolonged, and the imperious effects of a refuse landfill impervious layer can be enhanced; meanwhile, the medium-fine sands are readily available as they are low in cost and widely spread in China. The refuse landfill impervious system capable of prolonging breakdown time of the leachate has a simple structure and is able to effectively prevent the groundwater from permeating in order to saturate the medium-fine sand layer, keeping the medium-fine sand layer in an unsaturated state all the time.

摘要： A desalination method for improving topsoil of a saline-alkali land by using silt is disclosed. The method includes the following steps: (a) mixing topsoil of a saline-alkali land with silt, to form a mixed zone with a permeability coefficient of 1.Ox10-6 cm/s to 5.Ox1 0-5 cm/s; (b) building ridges around the mixed zone using silt, irrigating the mixed zone with fresh water for 2 to 4 months, and keeping a water depth of between 10 cm and 15 cm; and (c) planting rice in the mixed zone, and draining and irrigating the rice according to the growth characteristics and needs of the rice. Through mixing of topsoil of a saline-alkali land and silt, a mixed zone with a certain permeability coefficient is formed. In this way, a structure of the topsoil of the saline-alkali land can be improved, the soil fertility is improved, suitable conditions for the growth of rice are created, and a yield of the rice is improved. Moreover, after the structure of the topsoil of the saline-alkali land is improved by mixing with the silt, a permeability coefficient of the topsoil is decreased, and a permeation rate of a fresh water-containing soil layer is decreased, so that less fresh water can be used to maintain continuous downward permeation of fresh water, achieving salt-leaching and salt-reducing effects.

摘要： A dewatering method for dredged slurry which through high permeability cake is disclosed. The method sequentially includes the following steps: (a) adding a flocculant to dredged slurry to form floc-containing transition slurry; and (b) performing vacuum filtration on the transition slurry by using a geotextile as a filtering medium, to form a highly permeable cake on the surface of the geotextile, which could keep vacuum filtration durable and efficient to separate the water from the transition slurry. In the dewatering process, water can be extracted continuously for a long period since the mud cake generated from the formed flocs in the vacuum filtration process which has high permeability, so that not only the geotextile can be prevented from being blocked, but also water is allowed to permeate through the geotextile to achieve continuous dewatering effect. The dewatering method can rapidly reduce slurry volume, greatly improve efficiency, lower the costs, and require smaller operating area.
