The waste slurry generated by the construction of the underground diaphragm wall or the bored pile machine of the soft soil stratum by the double-wheel slot milling method can be simply divided into 2 types, one type is that the wall protection circulating slurry is discarded due to the increase of the specific gravity in the slot (hole) forming construction, and the waste slurry can be called as high specific gravity waste slurry; the other is waste of the slurry due to the rise of pH and pollution in the concrete pouring operation in the tank (hole), and the waste slurry can be called as the waste slurry with strong alkaline degradation.
The dehydration treatment of the high-specific gravity waste slurry in the construction site is divided into 4 processes of high-specific gravity waste slurry pre-screening treatment, first-stage desanding cyclone concentration treatment, second-stage desanding cyclone concentration treatment and filter pressing dehydration treatment.
(1) High specific gravity waste mud pre-screening treatment
The high-specific-gravity waste slurry is firstly sent into a double-layer vibrating screen 39 in the integrated waste slurry concentration filter press dehydrator device 3 to be subjected to pre-screening treatment, and large particles in the high-specific-gravity waste slurry are removed, so that the particle size in the pre-screened high-specific-gravity waste slurry meets the feeding requirement of a sand removal cyclone, and then the high-specific-gravity waste slurry enters a separate slurry storage box A in a separate slurry storage box 38.
(2) First stage desanding cyclone concentration treatment
A slag slurry pump 26 in the integrated pump set slag belt conveyor device 2 is connected with a slurry pipe 5 through a slag slurry pump feed, high specific gravity waste slurry in an A tank in a divided slurry storage tank 38 is pumped into a sand removal cyclone 3101 in a sand removal cyclone assembly 310 through a slag slurry pump feed connection slurry pipe 7, first-stage cyclone concentration treatment is carried out, higher specific gravity waste slurry flowing out from a sand setting port at the lower end of the sand removal cyclone 3101 enters an upper layer screen plate of a double-layer vibrating screen 39 for desliming, low specific gravity waste slurry flowing out from an overflow port at the upper end of the sand removal cyclone 3101 enters an A floating ball fluid supplementing tank 311 through an A overflow hose 312, and then flows into a B tank in the divided slurry storage tank 33 through an overflow port of the A floating ball fluid supplementing tank 311.
(3) Second-stage desilting cyclone concentration treatment
The method comprises the steps that a B slurry pump 26 in an integrated pump set slag tapping belt conveyor device 2 is connected with a slurry pipe 6 through a B slurry pump feed, low-specific-gravity waste slurry in a B tank in a separated slurry storage tank 38 is pumped into a deslagging cyclone 3131 in a deslagging cyclone assembly 313 through a B slurry pump feed connection slurry pipe 8, second-stage cyclone concentration treatment is carried out, lower-specific-gravity waste slurry flowing out from an overflow port at the upper end of the deslagging cyclone 3131 enters a B floating ball liquid supplementing tank 314 through a B overflow hose 315, and flows out through an overflow port of the B floating ball liquid supplementing tank 314 for recycling; the high-specific gravity waste slurry flowing out from the sand setting port at the lower end of the desilting cyclone 3131 enters the slurry collecting bucket 316, flows into the slurry storage tank 13 in the integrated pump stack slurry tank device 1 through the slurry discharge pipe 9, and is subjected to dehydration treatment by the filter press 32.
(4) Dewatering treatment of filter press
Firstly, a slurry supply pump set 18 in the integrated pump set slurry tank device 1 is started, a slurry pipe 4 is connected with the feeding of a filter press through a lower pipe valve switching assembly 110, waste slurry in a slurry storage tank 13 is pumped into the filter press 32 for filter pressing, feeding and dehydration treatment, and clean water and mud cakes are formed. After a period of time, the slurry supply pump set stops working, the air supply and storage device 16 is started, compressed air is sent into the membrane filter plates of the filter press 32, and squeezing dehydration is carried out, so that the waste slurry pumped into the filter press 32 forms clear water and mud cakes. The filtered clear water enters the water collection tank 24 through the water collection tank 33 and the water discharge bent pipe 34, and is automatically discharged through a pipeline additionally arranged in the water collection tank 24 to be used as water for diluting mud for recycling. The mud cake formed after the waste mud is dehydrated falls on the belt conveyor 22 in the integrated pump set slag discharging belt conveyor device 2, and is discharged through the belt conveyor 22.
Action of float fluid replacement tank 311 (314): when the liquid level in the A tank or the B tank in the divided pulp storage tank 38 is reduced, the position of the floating ball 3141 in the floating ball liquid supplementing tank 311 (314) is reduced, and the liquid supplementing port of the floating ball liquid supplementing tank 311 (314) above the floating ball 3141 is opened, so that the slurry in the floating ball liquid supplementing tank 311 (314) flows into the A tank or the B tank in the divided pulp storage tank 38, the liquid level in the tank is increased, and the continuous operation of the A (B) slurry pump 26 is ensured.
The dewatering treatment of the waste mud with strong alkaline degradation at the construction site is divided into 2 processes of pre-screening treatment and filter press dewatering treatment.
(1) Strong alkaline degradation waste slurry pre-screening treatment
The waste sludge with strong alkalinity is sent to a single-layer vibrating screen 15 in the integrated pump unit sludge box device 1 for pre-screening treatment, large particles in the waste sludge are removed, and then the sludge enters a sludge storage box 13 to be stirred by a stirrer 14 so as to prevent sludge sedimentation.
(2) Dewatering treatment of filter press
The filter press dehydration treatment process is the same as the filter press dehydration treatment (4), but the discharged clean water can not be discharged or utilized at random, and the corresponding treatment is carried out according to the pH value of the discharged clean water.
The distribution box 17 introduces power supply and distributes power, and through the distribution box 17, the A electric control cabinet 35 and the B electric control cabinet 25, the operation of the single-layer vibrating screen 15, the stirrer 14, the double-layer vibrating screen 39, the A (B) slurry pump 26, the slurry supply pump set 18, the filter press 32, the air supply and storage device 16 and the pipe valve switching assembly 110 can be controlled, and the pipe valve switching assembly 110 can also be manually switched. For example, the pipe valve switching assembly 110 can be switched by the clean water in the water tank to clean the pulp feed pump assembly 18 and the pulp pipe.
If the diaphragm filter press 32 is selected, the air supply and storage device 16 configured by the integrated pump unit mud box device 1 can charge compressed air into the diaphragm of the diaphragm filter plate in the diaphragm filter press 32 to swell the diaphragm of the diaphragm filter plate, and the mud cake formed between the two filter plates is compressed and dehydrated (also called as squeezing and dehydrating) so as to reduce the water content in the mud cake and further reduce the discharge amount of waste mud and dregs.
The integrated superposition type structure is adopted, so that the waste slurry concentration and dehydration integrated machine treatment equipment which does not need an installation period, is movable and is suitable for large-field treatment capacity of a construction site is realized, and the integrated superposition type structure has the advantages of small occupied area, high flexibility, environment friendliness, resource conservation and construction cost reduction.
