Abstract
The invention relates to a rain and sewage diversion system for a phosphogypsum yard, a water guide pipe (30) for guiding water at the rear part of the yard and the water seeped from a hillside to a down stream of the yard is arranged in a hill body (20) below the bottom of the valley-shaped phosphogypsum yard (100), an intercepting drain (60) for isolating the steep hillside from the yard is dug on the steep hillside (21) at the height of a slag heap, which corresponds to the maximum bearing capacity of the water guide pipe, the intercepting drain is communicated with a water accumulation region at the rear part of the yard and a region outside the yard, even a pipeline at the bottom of a reservoir is sunk, water level at the tail part of the reservoir only rises to the height of the intercepting drain, and then the water flows out the region of the yard from the intercepting drain, thereby avoiding forming a dammed lake, preventing a slag field from being destroyed by flushing, protecting the safety of the masses at the down stream of the slag field, and also preventing surface water from back-filling into the yard. The height of phosphogypsum accumulated on an anti-seepage membrane is always higher than the water level at the tail of the reservoir, and the problem that the anti-seepage membrane is jacked up and raised by underground water can be avoided during the running process of the slag field. The system selects one side with steeper slope of the hillside to build the intercepting drain, and the loss of reservoir capacity is minimal.
Description
Technical field
The present invention relates to the dirty separate system of rain of ardealite storage yard.
Background technology
Ardealite is the byproduct of phosphoric acid production.The P that every production is one ton
2O
5, with the by-product ardealite that produces 4.5 to 5.5 tons.Ardealite is mainly by calcium sulphate dihydrate (CaSO
42H
2O) form, and contain a spot of silicide and unreacted rock phosphate in powder.The ardealite total amount of the annual discharging of China is above 5,000 ten thousand tons.
Contain the higher acid pore water of contaminative in the pore water of ardealite, therefore, the storing up the place and generally all need lay density polyethylene film with high (HDPE film) of ardealite to prevent oozing contaminated environment under the acid water.The infiltration that the ardealite storage yard that is built in the shop film antiseepage in the mountain valley needs to reduce to greatest extent the peripheral hillside of surface water and stockyard that comes from the upper reaches, slag field gets into inside, slag field.Get into the slag field like excessive clean water, not only can increase the pressure of factory processes sewage, and can cause the ardealite mechanical property to change, influence slag field safety.
Surface water from the upper reaches generally can be through outside the catchwater guiding slag zone that is higher than the final design elevation in slag field.The pipeline of the general use of infiltration bottom the slag field from periphery hillside, stockyard draws toward downstream, slag field.Yet the final slag height of big-and-middle-sized ardealite storage yard can reach tens of rice even rice up to a hundred.Under huge burden pressure effect, the pipeline that is embedded in bottom, slag field subsides probably and makes and seeps water alluvial at rear portion, slag field (storehouse tail), thereby makes the storehouse tailwater level constantly rise, and finally pours in down a chimney within the slag field of laying antiseepage film.Run duration does not subside even pipeline is in the slag field; Several years after the storehouse is closed in the slag field or many decades be in the time, and pipeline also might stop up because of aging or silt alluvial, thus in the storehouse urogenesis barrier lake; The slag field of finally destroying by rush of water forms bigger threat to the downstream masses' safety.
Summary of the invention
Even the technical problem that the present invention will solve provide a kind of aqueduct in ardealite storage yard bottom subside or stops up after also can avoid surface water to gather forming barrier lake and cause that surface water pours in down a chimney the rain dirt separate system into ardealite slag field at rear portion, slag field.
For solving the problems of the technologies described above; The present invention provides a kind of rain of ardealite storage yard dirty separate system; Said ardealite storage yard is a mountain valley-type; Be provided with the water that the water and the hillside at rear portion, stockyard are oozed out in the massif under the ardealite storage yard bottom and lead aqueduct toward the downstream, stockyard; It is characterized in that, on the steep hillside at the pairing slag height of said aqueduct maximum load capacity place, dig and be provided with the catchwater that steep hillside and stockyard are kept apart, the zone outside the ponding zone that said catchwater is communicated with the rear portion, stockyard and the stockyard.
More than the pairing slag height of said aqueduct maximum load capacity, the ardealite slag is piled up to that side of slow hillside.
Adjacent inland dike and external wall are built through taking the ardealite slag in edge in the ardealite deposition region, between said inland dike and external wall, form the annular ditch of carrying ardealite slag slurry, form seepage flow between said external wall and edge, the stockyard antiseepage film and collect ditch; Form the new slag space of holding between the slow hillside of said external wall and shop film.
The present invention utilizes the inconsistent characteristics of hillside, both sides, the most mountain valley gradient, selects for use a gradient steeper side in hillside to be lower than the slag field and builds catchwater in the position of high design altitude, under the minimum situation of storage capacity loss; Formed the regional flowing water passage that is communicated with outside ponding zone, rear portion, stockyard and the stockyard; Even the bottom of the reservior pipeline subsides, the storehouse tailwater level also only rises to the elevation of catchwater, flows out the slag zone via catchwater then; Avoided the formation of barrier lake; Protected downstream, slag field masses' safety, prevented that the slag field from being destroyed by rush of water, prevented that also surface water from pouring in down a chimney into the stockyard.All the time be higher than the storehouse tailwater level owing to pile up the height of ardealite on the antiseepage film, the slag field antiseepage film can not occur by the problem of underground water jacking protuberance in the whole service process.
Further in the technical scheme; Slag of the present invention field from then on elevation begins to make the ardealite slag to pile up to the slow side of the hillside gradient; And the slag field method of operating that adopts the irrigation canals and ditches method takes the ardealite slag and builds up inside and outside dike; Interior external wall forms the annular ditch of carrying the slag slurry, and between external wall and slag field edge antiseepage film, forms seepage flow collection ditch.Lifting inland dike and external wall step by step form the new slag space of holding between the slow hillside of external wall and shop film.The acid fresh water (FW) that oozes out from the ardealite side slope and drop on rainwater on the ardealite side slope and all flow into around the seepage flow of slag field edge and collect the ditch comes back in the manufacturing process after collecting or discharge after Sewage Disposal is handled.And a gradient steeper side in hillside is higher than surface water on the hillside of catchwater and collects the back via catchwater and directly flow out the slag zone, thereby has avoided that rain is dirty to be mixed, and has reduced the amount of rainfall that gets into the slag field system, makes the stockyard more firm.
Description of drawings
Below in conjunction with accompanying drawing the present invention is done further detailed description:
Fig. 1 is the dirty separate system generalized section of the rain of ardealite storage yard of the present invention.
Fig. 2 is the dirty separate system generalized section of ardealite storage yard rain that adopts irrigation canals and ditches method lifting slag field to obtain.
The specific embodiment
As shown in Figure 1; Ardealite storage yard 100 involved in the present invention is a mountain valley-type, inconsistent, the as shown in fig. 1 mountain valley of the gradient, hillside, both sides, most mountain valley; The gradient on right side is steep than the gradient in left side, and the hillside, right side is called steep hillside 21, the hillside, left side is called slow hillside 22.Ardealite storage yard 100 has antiseepage film 10; Be embedded with in the massif below ardealite storage yard 100 bottom extreme lower position antiseepage film and come water and hillside infiltration to lead aqueduct 30 toward the downstream, stockyard with rear portion, stockyard (storehouse tail); The preferred aqueduct that adopts the very high HDPE pipeline of grade of compressive strength as bottom, slag field is in order to draw the hillside infiltration toward downstream, slag field the early stage of the operation in the slag field.Slag thickness is limited in the pre-slag storehouse, and underground water guide system normally plays a role, and underground water flows out the slag zone through the guide system, so groundwater table is lower, claims that the groundwater table of this moment is first groundwater table 201.Later stage, the aqueduct in the underground guide water system was crushed under the upper pressure effect along with (more than the antiseepage film) slag thickness in the slag storehouse is increasing, and the water of storehouse tail goes out not go, and water level lifting under the film reaches second groundwater table 202.On the steep hillside 21 at the pairing slag height of said aqueduct maximum load capacity place, dig and establish the catchwater 60 of keeping apart with the stockyard; Said catchwater is communicated with the ponding zone at rear portion, stockyard (storehouse tail) and the zone outside the stockyard; Like this; Can't draining even the aqueduct of bottom of the reservior subsides or stops up, rear portion, stockyard (storehouse tail) water accumulation level also only rises to the elevation of catchwater 60, flows out the slag zone via catchwater then.The underground water that makes lifting get up can flow away from catchwater, thereby has avoided groundwater table further to raise, and avoids the slag field of finally destroying by rush of water.
In the later stage; After the slag height reaches the pairing slag height of said aqueduct maximum load capacity, promptly more than the pairing slag height of said aqueduct maximum load capacity reaches, when continuing to stack the ardealite slag; Just pile up, and adopt the slag field method of operating of irrigation canals and ditches method to slow hillside 22 those sides.As shown in Figure 2, the method for operating of irrigation canals and ditches method refers to the ardealite slag 111 that edge near ardealite storage yard takes deposition and builds the twice ardealite dike that is parallel to the edge, stockyard.One dike near the edge, stockyard is referred to as external wall 106, and another parallel with it road dike is referred to as inland dike 104.Ditch between interior external wall is referred to as annular ditch 105.Ditch between external wall 106 and the slag field edge antiseepage film is referred to as seepage flow and collects ditch 107.Ardealite slag slurry flows along annular ditch, be transported to the slag field around.Simultaneously, from annular ditch, take the fill of ardealite slag, lifting inland dike and external wall step by step form the new slag space 110 of holding between the slow hillside of external wall and shop film, finally form ardealite side slope 108 as shown in Figure 1.The acid fresh water (FW) that oozes out from the ardealite side slope and drop on rainwater on the ardealite side slope and all flow into around the seepage flow of slag field edge and collect the ditch 107 comes back in the manufacturing process after collecting or discharge after Sewage Disposal is handled.And a gradient steeper side in hillside is higher than surface water on the hillside of catchwater and collects the back via catchwater and directly flow out the slag zone, thereby has avoided that rain is dirty to be mixed, and has reduced the amount of rainfall that gets into the slag field system, makes the stockyard more firm.
