Embodiment Construction

[0021] Referring to Fig. 1, the equipment for treating the leachate of domestic waste incineration plant according to the present invention includes a pretreatment system, a membrane bioreactor system and a disc-tube reverse osmosis system connected in sequence with the pretreatment system. The pretreatment system includes a leachate storage tank 1, a centrifugal dewatering device 3 connected to the leachate storage tank 1 through a first water pump 2, and an intermediate pool 4 connected to the centrifugal dewatering device 3 to remove suspended matter. The membrane bioreaction system includes a bioreactor 5 (commercially available), an ultrafiltration device 12 (commercially available) connected through a second water pump 11, and a blower 17 connected to the bioreactor 5. The disc tube reverse osmosis system includes a water storage tank 14 connected to the ultrafiltration device 12, and a disc tube reverse osmosis device 16 (commercially available) connected to the water st...

Abstract

The invention relates to device and method for garbage seep liquid in domestic waste incineration factory, which comprises: a storage tank for seep liquid, a centrifugal dewatering device connected to the tank by pump, a middle-tank pre-treat system connected to the dewatering device, a bioreactor, a membrane bioreaction system of superfilter device connected by pump, a water-storage tank connected to the superfilter device, and a dish-pipe reverse osmosis system of the device connected to the tank by pump. Besides, the method comprises: taking solid-liquid separation by sealing centrifugal dewater to get rid of seston; using membrane bioreaction system for biochemical reaction. This device has well integration, and the out water achieves first discharge requiry of national standard.

Description

technical field [0001] The invention relates to equipment and method for treating high-concentration organic waste water, in particular to equipment and method for treating garbage leachate in domestic garbage incineration plants using membrane biological reaction and reverse osmosis technology. Background technique [0002] Garbage leachate from domestic waste incineration plants is high-concentration organic sewage generated during garbage dumping, which mainly comes from the degradation of organic matter and the water contained in the garbage itself. It has been determined that it contains 93 kinds of harmful substances, of which 22 have been listed. On the key control list of my country and the US National Environmental Protection Agency, one of them can directly cause cancer, and five can induce cancer. In addition, the leachate also contains a large amount of heavy metal ions, bacteria, viruses, etc. Calculated by its pollution load, the contribution of one ton of leach...
