Description

Technical Field

[0001] The utility model relates to the technical field of construction water equipment, in particular to a novel slag-water separation and purification pool. Background Art

[0002] When the filter material of the sludge drying pool in the existing engineering project is too thick, it is easy to cause blockage. The floating objects (debris) float on the top layer, the water is in the middle, and the sludge is at the bottom layer. Since the floating objects (debris) cut off the contact surface between water and air, they cannot evaporate and filter naturally. When the filter material layer is too thin, it cannot achieve the purpose of filtration, resulting in unsatisfactory purification effect of sediment wastewater. When organic sludge is produced in the dried wastewater, a large amount of filter material will be taken away every time the sludge is cleaned. It is time-consuming and laborious to clean the sludge in the traditional sludge drying pool. Moreover, the sludge containing floating debris is not separated from the debris, which will cause new pollution to the environment by solid waste. It does not achieve the original intention of building a drying pool. Utility Model Content

[0003] The purpose of the utility model is to provide a new type of slag-water separation and purification tank to solve the problem that the existing traditional sludge drying tank mentioned in the background technology is time-consuming and labor-intensive to clean the sludge, and the sludge containing floating debris is not separated from the debris, which will cause new pollution to the environment by solid waste, and fail to achieve the original purpose of building a drying tank.

[0004] To achieve the above-mentioned purpose, the utility model provides a novel slag-water separation and purification tank, comprising a biological filler tank and a secondary anaerobic tank, wherein the biological filler tank is connected to the secondary anaerobic tank, a pedestal is installed on the outside of one end of the biological filler tank, a geotube bag is arranged on one side of the top of the pedestal, a steel mesh bag is installed on the top of the pedestal, a water inlet is arranged on the top of the steel mesh bag, two layers of crushed stone are laid in the steel mesh bag, and a geotextile is arranged between the two layers of crushed stone.

[0005] Preferably, the steel mesh bag is fixed to the top of the pedestal by high-strength bolts.

[0006] Preferably, one end of the biological filler tank is connected to the inner side of the support platform through a first filter pipe, and the first filter pipe is externally sheathed with a first pipe sleeve.

[0007] Preferably, the biological filler tank is connected to the secondary anaerobic tank via a second filter pipe, and the second filter pipe is externally sheathed with a second pipe sleeve.

[0008] Preferably, the side of the secondary anaerobic tank away from the biological filler tank is connected to a sedimentation tank through a third filter pipe, the third filter pipe is externally sheathed with a third pipe sleeve, and a water outlet is provided on one outer wall of the sedimentation tank.

[0009] Preferably, the tops of the biological filler tank, the secondary anaerobic tank and the sedimentation tank are all provided with dredging ports.

[0010] Preferably, exhaust pipes are installed on the tops of the biological filler tank, the secondary anaerobic tank and the sedimentation tank.

[0011] Preferably, the top of the exhaust pipe is a semicircular curved structure with the open end facing downward.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] In this new type of slag-water separation and purification tank, by setting a steel mesh bag on the base and laying two layers of crushed stone and geotextile in it, the purification tank achieves preliminary filtration and purification of wastewater, further improving the effect of slag-water separation. This design is not only simple and easy, but also low-cost and easy to maintain. By setting filter pipes and pipe sleeves between each tank body, the purification tank ensures the smooth flow and effective filtration of wastewater, while avoiding the problems of blockage and secondary pollution. This design enables the purification tank to operate continuously and stably, improving the efficiency and reliability of wastewater treatment. By setting a dredging port and an exhaust pipe at the top of each tank body, the purification tank is easy to clean and maintain, ensuring the long-term use effect of the equipment. At the same time, the semicircular curved structure design of the exhaust pipe effectively prevents rainwater and debris from entering, ensuring the normal operation of the equipment, and the equipment enhances the purification function of sediment wastewater. It is mainly used in sludge drying fields for engineering project construction. The pool can collect wastewater in the sludge drying field for re-filtration and use, preventing sludge wastewater from flowing arbitrarily. The wastewater in the sludge drying yard is filtered and used for sprinkling dust and maintaining greenery in the construction area, ensuring the principle of water conservation during the construction process.
