Description

Device for shunting stock dump runoff and percolate

Technical Field

The invention relates to a device for shunting stock dump runoff and percolate, in particular to a device for realizing the separation and discharge of surface runoff and internal shallow percolate in a particle stock dump of a large catchment surface such as a phosphogypsum stock dump or a refuse landfill.

Background

Phosphogypsum is a solid waste of phosphorus chemical industry, and most of the phosphogypsum belongs to common industrial solid waste. The most important method is stockpiling except the comprehensive utilization of building materials, cement retarders, agriculture and the like. The phosphorus chemical industry in provinces and cities such as Hubei and Guizhou is developed, and large-scale full-load valley type storage yards are mostly present. Rainfall seeps into the interior of a phosphogypsum storage yard and is mixed with the existing water stored in the phosphogypsum wet-process stack to breed more percolate, so that the quantity of harmful solutions containing acid, fluorine and the like and the disposal difficulty are increased. This requires that the yard surface runoff be separated as much as possible in advance without mixing with the leachate in the interior. The sealing is carried out by adopting measures such as thick clay layer covering and the like, so that the infiltration can be reduced; there is still a shallow percolate to be disposed of. For the storage yard in operation, the surface covering difficulty is very large, the catchment area is large, and the surface runoff and the in-vivo percolate are mixed more. If unified accumulation and recovery are handled, not only the regulation pond has overflow pollution risk, and the cost is very high moreover. For this purpose, systems like distribution of rain and sewage are required to isolate surface runoff from internal leachate.

Disclosure of Invention

The invention provides a device for shunting stock dump runoff and percolate, which comprises a main catchment channel, a porous percolate groove, a water outlet, a seesaw type bin groove, a liquid accumulation tank, an outer drainage channel and a regulation and storage tank, and adopts the technical scheme that: the main water collecting channel is arranged along the slope surface of the storage yard, and a water outlet and a porous infiltration groove are sequentially arranged at the bottom of the lower end from bottom to top; the seesaw type bin groove is erected above the bottleneck section of the liquid accumulation tank, the center of the seesaw type bin groove is positioned right below the porous permeation groove, the tilted end points to the outer drainage channel, and the sunk end points to the liquid accumulation tank; the outer drainage channel is guided to a rainwater garden type regulation and storage pool; the main water collecting channel, the outer water discharging channel and the liquid accumulating pool form a drop through vertical fall; a turnover baffle plate is cantilevered outside a water outlet at the lower end of the main catchment channel, and the main catchment channel consists of U-shaped channels with the seam width of 0.2-0.5 cm and glued at intervals in a dotted manner; the bottle neck mouth section of the liquid accumulation pool is provided with a slag settling tank.

The simple device mainly realizes the drainage of rainwater runoff on the surface of the storage yard and the independent collection of internal percolate, and reduces the quantity and the disposal difficulty of the percolate on the storage yard. The main catchment channel which is arranged from top to bottom and consists of point-shaped interval cemented U-shaped channels with the seam width of 0.2-0.5 cm is convenient for collecting surface runoff and shallow percolate; the main water collecting channel, the outer water discharging channel and the liquid accumulating pool form a drop water, so that a seesaw type bin groove is convenient to arrange; the bottom of the lower end of the main catchment channel is provided with a porous infiltration groove, so that the infiltration liquid with small flow rate falls downwards to the sinking section of the seesaw type bin groove and reaches the liquid accumulation pool; the seesaw type bin groove with the sinking end pointing to the liquid accumulation tank is convenient for collecting percolate falling down through the porous infiltration groove, the tilting end points to the outer drainage channel and is convenient for converting the tilting end and the sinking end under the radial flow impact of the water outlet, and the water flow discharged through the porous infiltration groove is synchronously conveyed to the outer drainage channel. The outer extension of main catchment ditch lower extreme delivery port is encorbelmented and is had the baffle that can overturn and be convenient for control the washing distance of runoff, easily lets the runoff fall in the storehouse inslot. The outer drainage channel is guided to the rainwater garden type regulation and storage pool to facilitate natural evaporation and plant transpiration. In the later stage of the initial rain stage and runoff discharge, the flow is small, and the seesaw type bin groove can return to the position of the sinking end pointing to the liquid collecting tank, so that polluted initial rain runoff and residual shallow percolate can be collected conveniently. The liquid accumulation pool with the slag settling groove arranged at the bottleneck section is convenient for accumulating and clearing solid matters.
