Description
Technical field
This utility model is related to a kind of shaped device of hollow fiber composite membrane.
Background technology
In prior art, with the deepening continuously of process of China's industrialization and urbanization, substantial amounts of industry and life are dirty
Dye thing is discharged in environment, and feedwater body brings increasingly severe pollution.The water quality deteriorating jeopardizes the strong of commercial production and people
Health, increased the cost that entire society obtains water resource.Shortage of water resources has become restriction China's economy and social development at present
Key factor.The freshwater resources of such as China are only 1/4, the 1/5 of the U.S. of world average level per capita, have been put into full generation
One of 13 poor-water countries of water resource per capita of boundary, are the whole world one of poorest countries of water resource per capita.And skewness, greatly
Amount freshwater resources concentrate on south, and northern freshwater resources only have the 1/4 of southern water resource.Some cities are excessively opened because of subsoil water
Adopt, define in hundreds of square kilometre of big funnel.Again due to the discharge of industrial wastewater, lead to more than 80% surface water,
Lower water is contaminated.More than Chinese The Great Lakes pool and the whole moderate of seven big water systems pollute, more than 21% monitoring section is bad V class water
Body；The city suburbs subsoil water of the 40% of the whole nation is contaminated, and more than 90% urban waters are seriously polluted.Brainstrust alerts：“20
After year, China will can not find drinkable water resource ".For this in every field, whether municipal public use water or industry enterprise
Industry, reusing sewage has had become as very urgent and real work.Enter new century, country puts sewage disposal strategic
The position of height, environmental planning institute of State Environmental Protection Administration predicts, China " 12 " and " 13 " period waste water treatment put into
1.05 trillion yuan and 1.39 trillion yuan will be respectively reached, reusing sewage resource market is very huge.
In recent years, membrane bioreactor (MBR) is widely used in Treated sewage reusing field due to having the characteristics that：
1. efficiently carry out solid-liquid separation, its separating effect is much better than traditional sedimentation tank, effluent quality is good, water outlet is hanged
Float and turbidity close to zero, can direct reuse it is achieved that sewage recycling；2. the efficient crown_interception of film, makes microorganism complete
Entirely it is trapped in bioreactor, realizes being kept completely separate of reactor hydraulic detention time (HRT) and sludge age (SRT), run
Control flexibly stable；3. because the Aeration tank that traditional wastewater is processed is united two into one by MBR with second pond, and instead of tertiary treatment
Whole process facility, floor space therefore can be greatly decreased, save construction investment；4. it is beneficial to the retention of nitrobacteria and numerous
Grow, system nitrification efficiency is high.Deamination and phosphorus removal functional also can be had by the change of the method for operation；5. because sludge age can be very
Long, thus greatly improving the degradation efficiency of hardly degraded organic substance；6. reactor is in high volumetric loading, low sludge loading, long sludge age
Lower operation, excess sludge production is extremely low, due to sludge age can endless, in theory can achieve zero sludge discharge；7. system realizes PLC
Control, convenient operation and management.
However, due in MBR technique aeration frequently, there is insufficient strength in usual film silk, the more phenomenon of fracture of wire.In addition,
Film silk is used in sewage disposal process, and sometimes due to silt, impurity etc. forms little scratch, crackle or film to the scraping of film silk
Top layer local shedding from hollow rope, thus forming stress concentration point, when continuing aeration shake, damaged or slight crack can be along this stress
Centrostigma continuous enlargement, ultimately forms rupture or fracture of wire, causes serious safety problem.
In view of as above reason is it is necessary to study a kind of shaped device of hollow fiber composite membrane, to solve in prior art
The problem existing.
