| titleOfInvention | A landfill leachate pretreatment device |
| abstract | The utility model discloses a landfill leachate pretreatment device, which comprises a dosing unit, a coagulation unit and a filter press unit. The coagulation unit comprises an oxidation reaction chamber, a sodium hydroxide reaction chamber and a sodium carbonate reaction chamber which are connected in sequence. The dosing unit adds corresponding reaction agents to the oxidation reaction chamber, the sodium hydroxide reaction chamber, and the sodium carbonate reaction chamber, respectively. There is a feeding pump, and the sodium carbonate reaction chamber is communicated with the filter press unit. The landfill leachate pretreatment device of the utility model integrates the filter press units, and at the same time, the sedimentation tank is omitted, the overall structure is compact, the area is small, and the utility model can be integrated and installed in a container, and is movable, and its rapid deployment capability is further improved; At the same time, the use of filter cake layer filtration greatly improves the quality of the effluent and reduces the fluctuation of the effluent quality, ensuring the stable operation of the back-end membrane system. |
