Wherein, NaOH, PAC and PAM is added when neutralization pond, coagulating basin and flocculation basin work in real time respectively；
2) step 1) treated percolate flows into primary sedimentation tank and is separated by solid-liquid separation, and clear liquid automatically flows into temperature control pond, adjusts Water temperature is to 30-35 DEG C；
3) after the clear liquid that temperature adjustment is completed in step 2) flows into the pond SBR, the pond SBR motor-driven valve is automatically turned on, and controls aeration time It is 8-16 hours, realizes aerobic state, then the pond SBR motor-driven valve is closed, and aeration stops, and tracheae emptying valve is opened, while automatic Diving mixer is opened, realizes anaerobic state, mixing time is 8-16 hours；
4) step 3) treated clear liquid flows into MBR membrane cisterna, and aeration plate is persistently aerated away from the place equipment bottom 400mm；
5) treated that water is pumped into clear water reserviors through suction pump for step 4, completes the processing of percolate.
Further, the temperature control pond passes through thermal resistance and sensor automatic water temperature regulation.
Further, the gas-water ratio in the step 4) in MBR membrane cisterna is 80: 1-150: 1, when aeration, and dissolved oxygen is adjusted To 2-4mg/L.
Further, MBR diaphragm uses hollow-fibre membrane.
Further, NaOH, PAC and PAM pass through respective metering pump respectively and are accurately added in the step 1).
Further, the MBR membrane cisterna is equipped with air lift pump, the start and stop of motor-driven valve in automatic control MBR membrane cisterna, and with Motor-driven valve links in the pond SBR, sludge reflux when aerobic state in the pond SBR, and when anaerobic state stops.
Beneficial effect using aforementioned present invention technical solution is:
Leachate in garbage transfer station processing method of the present invention uses automatic operation, and the manual intervention time is short, is convenient for system Maintenance, meanwhile, equipment operational process is short, operating cost is low.
Specific embodiment
It in order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below will be in the embodiment of the present invention Technical solution be clearly and completely described, it is clear that described embodiments are some of the embodiments of the present invention, rather than Whole embodiments.
A kind of leachate in garbage transfer station processing method of the present embodiment, includes the following steps:
1) landfill leachate stoste is pumped into neutralization pond by elevator pump after being collected by collecting pit and is neutralized, adjust PH to 7.0-8.5 is then successively pre-processed by coagulating basin and flocculation basin；
Wherein, pass through respectively when neutralization pond, coagulating basin and flocculation basin work metering pump real-time and precise be added NaOH, PAC and PAM；
2) step 1) treated percolate flows into primary sedimentation tank and is separated by solid-liquid separation, and clear liquid automatically flows into temperature control pond, described Temperature control pond is by thermal resistance and sensor automatic water temperature regulation to 30-35 DEG C；
3) after the clear liquid that temperature adjustment is completed in step 2) flows into the pond SBR, the pond SBR motor-driven valve is automatically turned on, and controls aeration time It is 8-16 hours, realizes aerobic state, then the pond SBR motor-driven valve is closed, and aeration stops, and tracheae emptying valve is opened, while automatic Diving mixer is opened, realizes anaerobic state, mixing time is 8-16 hours；
4) step 3) treated clear liquid flows into MBR membrane cisterna, and MBR diaphragm uses hollow-fibre membrane, and aeration plate is away from equipment Lasting aeration at the 400mm of bottom, wherein the gas-water ratio in MBR membrane cisterna is 80: 1-150: 1, and when aeration, dissolved oxygen is adjusted to 2- 4mg/L；
