Description
Technical field
The invention belongs to lake ecological controlling device field, be specifically related to a kind of solidifying with sand filtration and be integrated processing bottom mud in lakeDevice.
Background technology
Administer industry at inland lake and all know, the mud in shallow lake need regularly be collected and process, otherwise, withIncreasing of mud, not only can reduce the reservoir storage in lake, also can reduce the water quality of lake water. At present, to the silt in shallow lakeMud processing method mainly contains two kinds, and a kind of method is first to adopt grab bucket that the mud of lakebed is caught on sludge boat, then passes through sludge boatBy mud transport to that mud is on the bank stacked or the later stage stirs in stockyard, mud-water separation and solidify the subsequent treatment such as processing; AnotherKind method is first to adopt with the strand suction mud gathering-device of spiral cutting head will become silted up when the mud of lakebed is stirredThe silt stockyard that mud is drawn and is pumped into is on the bank stacked, or the later stage carries out mud-water separation and solidifies the follow-up places such as processing in stockyardReason. Administer industry at inland lake and all know, the upper strata of mud is mud scum, easily flows. Grab bucket for a kind of method before adoptingWhile excavating silt from the bottom of lake, can make the mud scum on upper strata float to other place. And pollutant in mud is mostly in mud scum. CauseThis, adopt grab bucket to collect mud, is not only difficult to improve the water quality of shallow lake, and mud scum can not inhale, and regulation effect is bad.Adopting with the strand suction mud gathering-device of spiral cutting head and collect mud, is will when the mud of lakebed is stirredMud is drawn onto on the bank, because lakebed is uneven, and the mud of lakebed is stirred in suction process, inevitably can be by lakebedProduce disturbance, can make the mud scum on mud upper strata drift about to other place, therefore, after adopting, a kind of method is to be difficult to maximum limit equallyLakebed mud scum is removed on degree ground, and governance efficiency is not high. On the other hand, because above-mentioned two kinds of methods all need to adopt sludge boat or carrier pipeThe silt stockyard that road is transported to the mud of collecting out is on the bank processed, and can not process on the spot at the scene, need to transportThe means of transport of mud or pipeline, make treatment cost higher. Because needs arrange silt stockyard on the coast, not only take cultivated againGround, also can bring secondary pollution to environment.

Further, the invention also discloses a kind of solidifying with sand filtration and be integrated the processing method of processing bottom mud in lake device, shouldProcessing method comprises following step:
The 1st step, floating platform 19 drive pick mud plough 1 to carry out mud diging working, and control system 20 starts first and takes out mud device 2 by lakebedMud pumps in bed mud pond 3, adds flocculant to stir in bed mud pond 3 simultaneously; When in mining process, pick mud is ploughed 1 jiaoSpend greatly, control system 20, by the angle of pick mud plough 1 is adjusted, is controlled between 15～60 °; To bed mud pond 3In flocculating setting operation, coagulation effect monitor 3-4 monitors in real time to whether flocculation is up to standard, as coagulation effect monitor 3-4 monitor bed mud pond 3 flocculates when below standard, sends signal to control system 20, and control system 20 is by controlled filter plate angleDegree motor 3-3 rotates, and makes tilt filtration plate 3-1 increase α angle value, and meanwhile, controlling bed mud pond agitating device 3-2 increasesRotating speed, promotes flocculant and bed mud to dissolve each other, and accelerates organic precipitation in bed mud; When coagulation effect monitor, 3-4 monitors the endThe completely up to standard and sludge content of mud sump 3 flocculating effects hour, sends signal to control system 20, and control system 20 is by controlFilter angle motor 3-3 processed rotates, and makes tilt filtration plate 3-1 reduce α angle value, meanwhile, controls bed mud pond and stirs dressPut 3-2 and reduce rotating speed, the energy consumption that minimizing equipment is unnecessary;
The 2nd step, control system 20 start the first muddy water water delivery device 5 a part of muddy water in bed mud pond 3 are transported to first successivelyIn sand filter 6, the second sand filter 7 and muddy water filtering ponds 8, the clear water after filtration is directly through the clear water of muddy water filtering ponds 8 bottomsDelivery pipe 9 enters in lake, and remaining muddy water is back in bed mud pond 3; When system detects the first sand filter 6 or the second sand filtration, there is obvious pressure drop phenomena in device 7 internal pressure shakinesses, control system 20 is controlled the first sand filter 6 or the second sand filter 7In pressure reduction control device start, increase the pressure differential of equipment, promote the flow velocity of liquid in pipeline;
The 3rd step, control system 20 start the 3rd muddy water water delivery device 11 and another part muddy water in bed mud pond 3 is transported to muddy water dividesIn device 12, control system 20 starts the second muddy water water delivery device 10 by the first sand filter 6 and the second sand filter 7 simultaneouslyIn mud pump in device for separating mud and water 12, muddy water separates in device for separating mud and water 12;
The 4th step, control system 20 start second and take out mud device 14 mud of device for separating mud and water 12 bottoms is pumped to storage basin 13In, the carrier pipe that mud is provided with through storage basin 13 bottoms is discharged in spiral agitator 16, simultaneously solidifying substance deposit pond 15 toIn spiral agitator 16, throw in solidifying substance, the bed mud after solidifying is displaced on belt conveyor 17 through discharging opening 16-5;
The 5th step, control system 20 start belt conveyor 17 bed mud are transported on sludge boat 18, and sludge boat 18 transports bed mudLake;
The 6th step, operate in engineering at muddy water filtering ponds 8, COD monitor 8-5 is monitoring the variation of COD in solution in real time, whenWhen COD monitor 8-5 monitors in muddy water filtering ponds 8 COD concentration over-standard, send signal to control system 20, controlSystem 20 is finely tuned motor 8-2 by angle and is driven filter plate synchronous cantilever 8-3 work, impels muddy water filter 8-1 to increase γ angleValue, controls into mud pipe magnetic valve 8-4 simultaneously and reduces into mudflow amount, thereby reduces the load of this equipment; As COD monitor 8-5Monitor COD concentration in muddy water filtering ponds 8 and return to normal value, send signal to control system 20, control system 20Finely tune motor 8-2 by angle and drive filter plate synchronous cantilever 8-3 work, impel muddy water filter 8-1 to reduce γ angle value, withIn time, is controlled into mud pipe magnetic valve 8-4 and increases into mudflow amount, thereby increases the disposal ability of this equipment;
The 7th step, in spiral agitator 16 work, axle temperature detector 16-6 implements spiral agitator 16 rotation situation to enterRow monitoring, in the time that mud resistance is excessive or the rising of long time running axle temperature exceeds safety margins, axle temperature detector 16-6 is to controlSystem 20 is sent signal, and control system 20 is cut off whole system power supply, and equipment is quit work, and produces audio alarm simultaneously;After equipment recovers normally, axle temperature detector 16-6 monitors axle temperature in safe range, sends signal to control system 20,Control system 20 is connected system power supply, and equipment is resumed work.
The disclosed one of patent of the present invention is solidified and sand filtration is integrated processing bottom mud in lake device and processing method thereof, its advantageBe:
(1) this installation cost is low, does not need occupied ground, and operation is convenient;
(2) this device adopts the two-layer filter of the inner employing of muddy water filtering ponds, and filter effect is better;
