Abstract

The invention discloses a sewage treatment system of a membrane-containing process, and an operation method of the sewage treatment system. The sewage treatment system comprises an anoxia pool, an aerobiotic pool, an MBR pool and a sterilization pool. The operation method comprises the following steps: firstly, opening a container, enabling immobilized microorganism spheres to flow into the system, collecting immobilized microorganism spheres which are used for a long time, and finally regenerating the collected immobilized microorganism spheres. Due to adoption of the immobilized microorganism spheres used in the sewage treatment system of the membrane-containing process and the operation method of the sewage treatment system, not only is the activity of microorganism maintained, but also sludge and water can be separated, so that membrane pollution can be reduced; diameters of the immobilized microorganism spheres are appropriately selected, the immobilized microorganism spheres can be suspended without a relatively great magnetic field, and the sewage can contact microorganisms inside the immobilized microorganism spheres; due to the action of the magnetic field, the immobilized microorganism spheres can be at a suspended state, and the microbial activity can be also improved; the immobilized microorganism spheres can be recycled and reused, so that the biological activities of the immobilized microorganism spheres can be constantly kept at a high activity state.

Description

A kind of sewage disposal system containing membrane process and its operational approach
Technical field
The present invention relates to sewage treatment area, a kind of sewage disposal system containing membrane process and its operational approach.
Background technology
China is the most unbalanced country of distribution of water resources, and the water resource that each place has is the most unbalanced, totally On be a hydropenia country, the whole nation has the city of 70% to be in exsiccosis;China or a with serious pollution state of water simultaneously Family, annual because water pollutes the loss caused accounts for the 2% of GDP, water pollution condition is constantly aggravated so that sewage disposal and regeneration Industry is by unprecedented concern.
Being mainly used in denitrogenation in anoxic pond, nitrate nitrogen is back to anoxic pond by interior circulation by MBR pond;Aerobic Pond is used for Except BOD, ammonia and nitrogen organic and nitrification and absorption phosphorus in water, Organic substance in water is decomposed into inorganic matter;MBR pond is used for purifying Water, the water after MBR pond is filtered can be expelled directly out through sterilization again.
MBR is membrane bioreactor, carries the key player ensureing high-quality water quality output, is cut by the impurity in sewage Staying through degrading to greatest extent, be achieved dirty water purification, sewage is in the reactor through having carried out a biological disposal upon to organic dirt After the decomposition of dye material and conversion, utilize the high efficiency separation of micro-filtration membrane or ultrafilter membrane to complete the solid-liquid separation of sewage, thus reach The final purification effect of sewage.The membrane module being arranged in reactor can replace the second pond in traditional handicraft and conventional mistake completely Filter, absorbing unit, make hydraulic detention time and sludge age be kept completely separate, and obtains stable, the effluent quality of high-quality.
During membrane process sewage disposal, mud often can be attached on membrane module, causes membrane module fenestra to be hindered by mud Plug and cause purifying water efficiency and reduce, to this end, enterprise is required for devoting a tremendous amount of time and clear for fouling membrane of money every year Clean.
