Detailed description of the invention
The treatment system that multisystem shunting is carried out in refuse landfill is described in detail to of the present invention below in conjunction with embodiment and accompanying drawing.
As shown in Figure 1 and Figure 2, treatment system of refuse landfill being carried out to multisystem shunting of the present invention, comprise the landfill operation district 10,11,12 of more than 2 be separated into by water retaining dike 5 by elevation, the landfill operation district (10,11,12) of described more than 2 is laid on the acclive sloping floor of tool, and the described gradient is 1% ~ 5%.Be provided with the Leachate site guide system 1, Leachate site detection system 2 and the underground water guide system 3 that are layed in refuse landfill below ground in each landfill operation district 10/11/12, described underground water guide system 3 is arranged on the below of Leachate site guide system 1.Leachate site guide system 1 is interconnected primarily of the primary and secondary pipeline (guide pipeline mainly adopts high density polyethylene pipe) of Leachate site guide and forms (garbage leachate etc. is exported to regulating reservoir).Leachate site detection system 2 is interconnected and forms primarily of the primary and secondary pipeline (pipeline mainly adopts high density polyethylene pipe) that Leachate site detects (whether seepage occurring by observing pipeline whether water outlet carrying out seepage control system at the bottom of checkout area).Leachate site guide system 1, Leachate site detection system 2 and underground water guide system 3 are laid in vertical direction layering.An integrated treatment well 4 is provided with in each landfill operation district 10/11/12, described integrated treatment well 4 is connected with the sewage approaching side of the water retaining dike 5 in the landfill operation district 10/11/12 at place, be arranged on Leachate site guide system 1 in last landfill operation district 10/11/12 and underground water guide system 3 to run through described water retaining dike 5 and be connected integrated treatment well 4 in next landfill operation district 10/11/12, and be connected with underground water guide system 3 with the Leachate site guide system 1 be arranged in this landfill operation district 10/11/12 by described integrated treatment well 4, integrated treatment well 4 in the landfill operation district, connection place, one end 10/11/12 of described Leachate site detection system 2.
Leachate site guide system 1 in landfill operation district 10,11,12 more than described 2, be provided with seepage control system 13 between Leachate site detection system 2 and underground water guide system 3, the seepage control system 13 in the landfill operation district 10,11,12 of more than 2 all runs through corresponding water retaining dike 5 and is interconnected.
As shown in Figure 3, Figure 4, described integrated treatment well 4 includes a Room A, two Room B and three Room C, the Leachate site guide pipeline 14 for connecting the Leachate site guide system 1 in adjacent Liang Ge landfill operation district 10/11/12 is provided with in a described Room A, described Leachate site guide pipeline 14 is disposed radially the blind flange 7 that can insert and dismantle, described Leachate site guide pipeline 14 is also connected with two Room B, and described Leachate site guide pipeline 14 is connected with two Room B with the first connectedness 15 by electric gate valve 8 successively; Two described Room B connect described Leachate site detection system 2 by the second connectedness 16 be arranged on locular wall, are provided with the ultrasonic level gage 9 for detecting indoor liquid in two described Room B; Underground water guide pipeline 17 is provided with in three described Room C, described underground water guide pipeline 17 is three-port structure, a port of described three-port structure is for receiving rainwater and being provided with rain perforaled strainer 6, and another two ports of described three-port structure connect the underground water guide system 3 in adjacent landfill operation district 10/11/12 respectively.
The material of described integrated treatment well 4 adopts high density polyethylene (HDPE) (HDPE), integrated treatment well 4 carries out connection handling with it through the material of impervious barrier at the bottom of field, wherein can restricting with mistake binding PE with sodium bentonite blanket layer in seepage control system 13 and carry out connection handling, carrying out sweat soldering with seepage control system 13 medium high density polyethylene rete by adopting pipe to wear film mode.
As shown in Figure 1, the plant area of the refuse landfill of the present embodiment is divided into several landfill operation districts (only showing 1st district, 2nd district and 3rd district in Fig. 1) centre temporary water dash dike 5 by elevation and separates, as seen from Figure 1, the physical features of this landfill yard is the gradient of 1 ~ 5%, and subregion divides by physical features.
At landfill yard initial operating stage, the landfill operation 10 that elevation is low first runs, landfill operation district 11 and landfill operation district 12 also do not run, the integrated treatment well 4 being now arranged on landfill operation district 10 and off-duty landfill operation district 11 intersection run will play the effect of rain dirt shunting, install by the blind flange 7 on the Leachate site guide pipeline 14 of a Room A in integrated treatment well 4, the surface water in inoperative landfill operation district can be accessed the entrance of three Room C of integrated treatment well 4 simultaneously, by rain perforaled strainer 6, untainted surface water is caused described underground water guide system 3, as shown in Figures 3 and 4, greatly reduce the treating capacity of initial operating stage Leachate site, save operation cost.As long as landfill yard starts new landfill operation district, above-mentioned technique can be run successively.
When the landfill operation district 10 of landfill yard, landfill operation district 11 and landfill operation district 12 all run, the blind flange 7 on the Leachate site guide pipeline 14 of a Room A in integrated treatment well 4 is needed to remove, Leachate site guide system 1 is run according to normality, needs the entrance shutoff of integrated treatment well 4 three Room C simultaneously.Now, Leachate site detection system 2 needs normal operation, and namely Leachate site detection system 2 pipeline has accessed two Room B of integrated treatment well 4, arranges ultrasonic level gage in two Room B, seepage is there is with or without destruction, as shown in Figure 3 by monitoring level monitoring affiliated area bottom seepage control system.In addition, two Room B of integrated treatment well 4 are connected with the Leachate site guide pipeline 14 of a Room A by electric gate valve 8, when bottom seepage of seepage-proof layer is more serious, electric gate valve 8 can be opened, the Leachate site of seepage is entered the process of leachate treatment system by the temporary transient guide of Leachate site guide system 1.
