Leachate treatment integrated equipment
Technical Field
The utility model belongs to the technical field of waste water treatment, in particular to landfill leachate handles equipment of integrating.
Background
Chemical Oxygen demand (cod) (chemical Oxygen demand) is a chemical method for measuring the amount of reducing substances to be oxidized in a water sample. The oxygen equivalent of a substance (typically an organic substance) that can be oxidized by a strong oxidizing agent in wastewater, wastewater treatment plant effluent, and contaminated water. In the research of river pollution and the property of industrial wastewater and the operation management of wastewater treatment plants, it is an important and relatively fast measurable organic pollution parameter, often denoted by the symbol COD. The ammonia nitrogen refers to nitrogen existing in the form of free ammonia (NH3) and ammonium ions (NH4+), is a nutrient in the water body, can cause water eutrophication, is a main oxygen-consuming pollutant in the water body, and is toxic to fishes and certain aquatic organisms.

An MBR Membrane-bioreactor (MBR) is a new type of wastewater treatment system that combines Membrane separation technology and biological treatment technology. The membrane component replaces a secondary sedimentation tank at the tail end of the traditional biological treatment technology, the concentration of the high-activity sludge is kept in a bioreactor, the organic load of biological treatment is improved, the occupied area of a sewage treatment facility is reduced, and the excess sludge amount is reduced by keeping low sludge load. According to whether the membrane bioreactor is aerobic or not: can be divided into aerobic and anaerobic membrane bioreactors.
Aerobic membrane bioreactors are commonly used in municipal and industrial processes, where the use of aerobic MBRs in municipal sewage treatment is generally intended to achieve the purpose of reusing the effluent, and in the treatment industry primarily to remove specific contaminants, such as greasy and oily contaminants.

For example, the UASB is combined with the membrane unit, and the anaerobic membrane bioreactor does not need a designed three-phase separator to realize the separation of solid, liquid and gas; for the two-phase anaerobic MBR, the concentration of acid-producing bacteria in acid-producing reaction gas is increased due to the membrane separation effect, the hydrolysis fermentation capacity is improved, and meanwhile, macromolecular organic matters are retained in the acid-producing reactor by the membrane to be subjected to hydrolysis fermentation, so that the higher acidification rate is maintained. Anaerobic membrane bioreactors are used for the treatment effect of high-concentration organic water diversion, and because the membrane bioreactor lacks aeration, in order to enable anaerobic sludge to be in a suspended state, the anaerobic membrane bioreactor for treating high-concentration organic wastewater is split.
