Abstract
The invention discloses a long-distance pipeline coal transporting head-end wastewater treatment system and a treatment method. The system comprises a drainage ditch, a water collection pit, a sweeping pump, a waste slurry pool, a submersible slurry pump and a coal-dressing concentration workshop, wherein washed wastewater is collected to the drainage ditch through a trench or a pipe, the water collection pit is connected with the waste slurry pool through the pipe, wastewater in the water collection pit is transferred to the waste slurry pool through the sweeping pump, and the waste slurry pool is connected with the coal-dressing concentration workshop through the submersible slurry pump and the pipe. The washed wastewater treatment system and method disclosed by the invention are wide in application scope and easy to operate, and can greatly reduce the operation cost of deep treatment; the recovery rate of wastewater is more than 95%; colors, odors and most of organic pollutants and poisonous heavy metal substances in water can he effectively removed, thereby reducing the turbidity of water; and the system and method disclosed by the invention are economic and reasonable, low in energy consumption, and widely used in the coal water slurry pipeline transporting industry.
Description
Technical field
The present invention relates to wastewater treatment, be specifically related to the defeated coal head end Waste Water Treatment of long-distance pipe and processing method.
Background technology
In general, on the one hand, the present sewage treatment capacity of China does not still catch up with the rapid expansion of water scale, and the auxiliary facility construction such as pipe network, Treatment of Sludge seriously lag behind.On the other hand, the wastewater treatment rate of China also exist obvious gap, and the rate of load condensate for the treatment of facility is low compared with developed countries.
Wastewater treatment in China is experiencing by small scale, level is low, kind is single, seriously can not satisfy the demands to has the deep transformation that considerable scale and level, variety and quality significantly improved and tentatively satisfied national economic development requirement, and the sewage disposal demand will progressively realize self-sufficiency.Although because country and governments at all levels are to the improving constantly of environmental protection attention degree, Chinese sewage treatment industry is just at rapid growth, the sewage disposal total amount increases year by year, and the town sewage handling rate improves constantly.But present Chinese sewage treatment industry still is in the primary stage of development.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structurely, easy to operate, improve to greatest extent the flushing waste water treatment system of the defeated coal slurry head end of pipe of coal recovery rate.
Another object of the present invention provides method of wastewater treatment.
In order to overcome the deficiencies in the prior art, technical solution of the present invention is to solve like this: the defeated coal head end Waste Water Treatment of a kind of long-distance pipe comprises the gutter, catch pit, the slag stock pump, useless stock tank, coal separation concentrates the workshop, special character of the present invention is that described flushing waste water is pooled to the gutter along ground line gradient, described gutter is connected with catch pit by pipeline, described catch pit is connected with useless stock tank by sweep the floor pump and pipeline, and described useless stock tank is connected with the concentrated workshop of coal separation by diving slurry pump and pipeline.
A kind of method of wastewater treatment of described system, carry out successively in the steps below:
1), does the gutter at gatehead and slurrying surge bunker bottom architecture indoor below ground, the collection flushing waste water;
2), flushing waste water imports indoor catch pit after collect in the gutter, establish grid or screen pack in the catch pit;
3), the black water in the waste water through the gutter, grid or the screen pack precipitation of catch pit, hold back, contain the less waste water of coal slime in the useless stock tank and be delivered to the concentrated workshop recycling of head end coal separation by diving slurry pump;
4), hold back with the coal slime periodic cleaning that precipitates to the recycling of coal slime pond in gutter, catch pit, the useless stock tank.
The present invention compared with prior art, this each inter process of flushing waste water treatment system is rationally distributed, procedure connection is good, uses this system and can reclaim fully coal slime in the waste water, improves coal recovery rate.Be widely used in the water-coal-slurry pipeline carrier have simple in structure, easy to operate, environmental protection, energy-saving and emission-reduction and improve to greatest extent the order of coal recovery rate.
Description of drawings:
Fig. 1 is Waste Water Treatment structural representation of the present invention.
Among the figure: the 1-flushing waste water, the 2-gutter, 3-catch pit, 4-one slag stock pump, the 5-stock tank that gives up, the 6-diving slurry pump, the 7-coal separation concentrates the workshop, 8-coal slime pond.
The specific embodiment
Accompanying drawing is embodiments of the invention.
Below in conjunction with accompanying drawing content of the present invention is further described:
With reference to Fig. 1, the defeated coal head end Waste Water Treatment of a kind of long-distance pipe comprises the gutter, catch pit, the pump of sweeping the floor, useless stock tank, coal separation concentrates the workshop, described flushing waste water 1 is pooled to gutter 2 along ground line gradient, described gutter 2 is connected with catch pit 3 by pipeline, and described catch pit 3 is connected with useless stock tank 5 by sweep the floor pump 4 and pipeline, and the described pond 5 of transferring is connected with the concentrated workshop 7 of coal separation by diving slurry pump 6 and pipeline.
A kind of method of wastewater treatment of described system, carry out successively in the steps below:
1), does gutter 2 at gatehead and slurrying surge bunker bottom architecture indoor below ground, collection flushing waste water 1;
2), flushing waste water 1 imports indoor catch pit 3 after collect in gutter 2, establish grid or screen pack in the catch pit 3;
3), the black water in the waste water 1 through the gutter 2, grid or the screen pack precipitation of catch pit 3, hold back, contain the less waste water of coal slime in the useless stock tank 5 and be delivered to concentrated workshop 7 recyclings of head end coal separation by another diving slurry pump 6;
4), hold back in gutter 2, catch pit 3, the useless stock tank 5 with the coal slime periodic cleaning that precipitates to coal slime pond 8, recycle.
In sum, the defeated coal head end Waste Water Treatment of long-distance pipe involved in the present invention and processing method, rationally distributed between device, be connected good between technique, the flushing waste water major impurity is coal slime, cinder and a small amount of greasy dirt, according to current specifications and practical experience, take first certain measure to hold back the bulk cinder, hold back and contain the less waste water of coal slime behind the cinder and discharged by water pump single tube pressure, finally enter the flushing waste water treating stations and focus on reuse, the auxiliary facility of pipe network and Treatment of Sludge is advanced, and the rate of load condensate for the treatment of facility is high.
The above has carried out exemplary description to the present invention by reference to the accompanying drawings; obvious realization of the present invention is not subjected to the restriction of aforesaid way; as long as the various improvement of having adopted device design of the present invention and technical scheme to carry out; or without improving design of the present invention and technical scheme are directly applied to other occasion, all in protection scope of the present invention.
