Problems solved by technology
[0002] In the leachate treatment process, the cooling, defoaming, and sludge discharge of the nitrification tank are usually designed as three routes. A separate sewage cooling tower pipeline, a separate defoamer dosing pipeline, and a separate sludge discharge pipeline make the nitrification tank There are many and complicated pipelines. The more pipelines, the greater the possibility of blockage, leakage, and corrosion, and the greater the intensity of maintenance work. Moreover, the cost of adding antifoaming agents is not only expensive, but also the ingredients in the agents will have a certain impact on water quality. influence, indirectly affects the processing effect of the system

The invention relates to a cooling device with both mud discharging and defoaming functions. The cooling device consists of a sewage inlet pipe, a nitrification heat exchanger, a sewage outlet pipe, adefoaming main pipe, defoaming branch pipes, defoaming spray holes, a mud discharging pipe, a clear water inlet pipe, a clear water outlet pipe and a cooling tower. The sewage inlet pipe is connectedto an outlet of a sewage circulation pump, and the nitrification heat exchanger is communicated with the sewage inlet pipe, the sewage outlet pipe, the clear water inlet pipe and the clear water outlet pipe; the sewage outlet pipe is connected to the defoaming main pipe; the defoaming main pipe is connected to the defoaming branch pipes; the defoaming branch pipes are evenly distributed above a nitrification tank; the defoaming spray holes are evenly distributed on the defoaming branch pipes; the mud discharging pipe is connected to the middle area of the defoaming main pipe; the clear waterinlet pipe is connected to the cooling tower; the clear water outlet pipe is connected to the nitrification heat exchanger; and the cooling tower is connected to the clear water outlet pipe.
Description
technical field [0001] The invention relates to the technical field of leachate treatment, in particular to a cooling device with functions of mud discharge and defoaming. Background technique [0002] In the leachate treatment process, the cooling, defoaming, and sludge discharge of the nitrification tank are usually designed as three routes. A separate sewage cooling tower pipeline, a separate defoamer dosing pipeline, and a separate sludge discharge pipeline make the nitrification tank There are many and complicated pipelines. The more pipelines, the greater the possibility of blockage, leakage, and corrosion, and the greater the intensity of maintenance work. Moreover, the cost of adding antifoaming agents is not only expensive, but also the ingredients in the agents will have a certain impact on water quality. The impact of the system indirectly affects the processing effect of the system. Therefore, a cooling device with both sludge discharge and defoaming functions i...
