Abstract

The invention belongs to the technical field of landfill leachate treatment, in particular to a membrane advanced treatment integrated module device for landfill leachate. The membrane advanced treatment integrated module device for landfill leachate provided by the invention integrates ultrafiltration, nanofiltration and reverse osmosis into a membrane integrated module through a system, therebyrealizing high-efficiency treatment of landfill leachate. At that same time, the treatment system of the device is safe, simple in maintenance, convenient in operation, high in automation degree, compact and flexible in layout, highly stable in interception effect of the whole system, strong in adaptability to the inlet water quality of the leachate, can meet the operation needs of different waterquality conditions, has high economic benefit, and is worthy of being popularized and used in a large area.

Description

technical field [0001] The invention belongs to the technical field of landfill leachate treatment, and in particular relates to an integrated module device for advanced membrane treatment of landfill leachate. Background technique [0002] Domestic waste treatment methods mainly include incineration, composting, mechanical treatment and landfill. During the stacking, transfer, extrusion, transportation, landfill or incineration of garbage, a variety of metabolites and water will be produced, forming a highly concentrated organic wastewater with extremely complex components - landfill leachate; untreated landfill leachate is harmful to the environment. The surrounding groundwater, surface water, soil, atmosphere, organisms, etc. will cause serious environmental pollution. After flowing through the surface or infiltrating into the groundwater, it will destroy the ecological balance of the surrounding soil, cause soil or water pollution, and cause serious secondary damage to t...
