Abstract
The utility model provides a high hydraulic load ground infiltration system which comprises a surface cover layer, a water distribution groove, a water distribution pipe arranged in the water distribution groove, a first manual packing layer, a second manual packing layer, a bottom bearing layer and a water outlet pipe, and is characterized in that a clay layer is arranged between the first manual packing layer and the second manual packing layer; the first manual packing layer as well as the second manual packing layer comprises a fine-particle vermiculite layer and a coarse-particle vermiculite layer; the fine-particle vermiculite layer is paved on the coarse-particle vermiculite layer. The high hydraulic load ground infiltration system is obtained by improving a conventional ground infiltration system, so as to improve the hydraulic load of the ground infiltration system, stand over blockage conditions, and enhance sewage disposal effect.
Description
Technical field
The utility model belongs to sewage treatment area, is specifically related to a kind of land percolation system.
Background technology
Polluted water land is processed a kind of method as Prevention of Water Pollution in Rural Area, since the eighties in 20th century, just revived abroad as the innovation substitute technology and develop, in the world many countries all active research with widely popularize the polluted water land treatment system.Especially at Rural Water resource pollution also increasingly serious today; the mass-producing centralized sewage treatmentmethod in city is not fit to again the needs of rural sewage treatment; thereby should set about considering the polluted water land disposal method of land percolation system this adaptation rural area characteristics; it is good that it has a treatment effect; less investment; the advantages such as operational management is convenient, and is simple to operate, and working cost is low.Promote land treatment technique, especially at Small Urban, sewage focused on to combine with dispersion treatment will become the only way of the sewage disposal that is fit to China's national situation gradually.But, also there is the defective that is difficult to overcome in the polluted water land treatment system.Because the core of traditional land treatment system is to utilize natural soil layer as filtration media, therefore, exists hydraulic load low, the problems such as the easy obstruction of long-play, this has limited to a certain extent polluted water land and has processed and the development that utilizes.
The utility model content
The purpose of this utility model provides a kind of land percolation system of high hydraulic load, in order to solve existing low, the susceptible to plugging problem of conventional land percolation system's hydraulic load.
The technical solution of the utility model is as follows:
A kind of high hydraulic load land percolation system, comprise surface coating, cloth tank, be arranged on water distributor, the first artificial packing layer, the second hand-stuff layer, bottom supporting layer and rising pipe in the cloth tank, it is characterized in that: also be provided with clay seam between the described first artificial packing layer and the second hand-stuff layer, the described first artificial packing layer and the second hand-stuff layer consist of by fine particle vermiculite layers and coarse particles vermiculite layers, and the fine particle vermiculite layers is layed on the coarse particles vermiculite layers.
The cross section of described cloth tank is trapezoidal, high 10cm, lower bottom width 10cm, upper bottom width 20cm.Be equipped with gravel and clay in the cloth tank, in order to hold back the suspended particle in the sewage.
Described surface coating is soil and plant.
The thickness of described fine particle vermiculite layers and coarse particles vermiculite layers is 10～20cm, and the particle diameter of described fine particle vermiculite is 1～2mm, and the particle diameter of coarse particles vermiculite is 3～7mm.
Described bottom supporting layer is gravel bed, and thickness is 5～10cm.The current of the rising pipe that arranges in the supporting layer of bottom after in order to emission treatment.
The beneficial effects of the utility model are: relatively existing land percolation system, be provided with two artificial packing layers in the agent set of the present utility model, and all adopted thick, thin two kinds of vermiculite layers as filtering layer, can increase the amount of microorganism in the land percolation system, strengthen the activity of hand-stuff, and then improve hydraulic load and wastewater treatment efficiency.Two artificial packing layers are directly laid one deck clay, can hold back the suspended substance in the sewage that is got off by the upper strata diafiltration, thereby delay the obstruction of whole system.
Description of drawings
Fig. 1 is one-piece construction schematic diagram of the present utility model; 1 is surface coating; 2 is the first artificial packing layer; 3 is clay seam; 4 is the second hand-stuff layer; 5 is the bottom supporting layer; 6 is rising pipe; 7 is the cloth tank; 8 is water distributor.
Embodiment
The high hydraulic load land percolation system that the utility model proposes, be followed successively by surface coating 1, the first artificial packing layer 2, clay seam 3, the second hand-stuff layer 4, bottom supporting layer 5 and rising pipe 6 from top to bottom, in surface coating, also be provided with cloth tank 7, water distributor 8 is installed in the cell body.Described surface coating is soil and plant, and cloth tank middle berth is provided with clay and gravel, and the cross section of cloth tank is trapezoidal, high 10cm, lower bottom width 10cm, upper bottom width 20cm.The first artificial packing layer and the second hand-stuff layer are followed successively by fine particle vermiculite layers and coarse particles vermiculite layers from top to bottom, and thickness is 10～20cm, and the particle diameter of described fine particle vermiculite is 1～2mm, and the particle diameter of coarse particles vermiculite is 3～7mm.The bottom supporting layer is gravel bed, and thickness is 5～10cm.The current of the rising pipe that arranges in the supporting layer of bottom after in order to emission treatment.Adopt aforesaid method, can effectively improve the hydraulic load of land percolation system, delay blockage, the enhanced sewage treatment effect.
