Embodiment Construction
[0033] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0034] It should be noted that when an element is referred to as being “fixed on” or “disposed on” another element, it may be directly on the other element or there may be an intervening element at the same time. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present.
[0035] In addition, it should be noted that the orientation terms such as left, right, up, and down in the embodiments of the present invention are only relative concepts or refer to the normal use state of the product, and...

The invention belongs to the technical field of domestic garbage leachate treatment, and discloses a leachate treatment device, which comprises a collection tank, a grid assembly arranged in the collection tank, a first pipeline and a treatment system, wherein the treatment system comprises a high-voltage pulse electric flocculator, a second pipeline, a UASB anaerobic reaction tower, a third pipeline, an MBBR bio-membrane reactor, a fourth pipeline, an MBR membrane reactor, a fifth pipeline and a sludge dewatering system. According to the invention, by arranging the grid assembly in the collection tank, the large-particle impurities in the leachate and the oil stains on the surface of the leachate can be filtered out; and by arranging the high-voltage pulse electric flocculator, the secondpipeline, the UASB anaerobic reaction tower, the MBBR bio-membrane reactor, the MBR membrane reactor and the sludge dewatering system, the sewage discharge treatment of the leachate can be realized,and the situation that the sedimentation tank needs to be built to realize the sewage treatment of the leachate in the traditional device is completely avoided, so that the occupied space of the leachate treatment device is small so as to meet the requirements of a small-sized garbage transfer station.
Description
technical field [0001] The invention belongs to the field of domestic garbage leachate treatment, and more specifically relates to a leachate treatment device. Background technique [0002] With the acceleration of China's urbanization process, the urban population and scale continue to expand, and the resulting production and domestic waste have increased exponentially. The leachate of the urban waste transfer station is composed of the leachate stock solution produced during the garbage compression process and the ground flushing sewage in the operation area during the transfer process. The water quality of the leachate stock solution varies greatly, with many types of organic pollutants and high concentrations. There are many carcinogens, cancer promoters and metal ions. When landfill leachate infiltrates into groundwater and surface water, it will pollute the quality of surface water and have a direct impact on human health and industrial and agricultural water sources....
