Description
Technical field
The present invention relates to a kind of sewage-treatment plant, more specifically relate to a kind of column type hollow fiber membrane modular.
Background technology
Fast development along with China's economy, the consumption of water resource is multiplied, caused on the one hand the in short supply of water resource, also increased the generation of sewage simultaneously, strengthened the pressure of society and environment sustainable development, the parties concerned drop into a large amount of funds and sewage are processed to and made its resource recycling for this reason.Membrane separation technique and device have been widely used in the sewage treatment areas such as biology, chemical industry, medicine, food, municipal administration in recent years.For the ease of suitability for industrialized production and installation, improve the operating efficiency of film, in unit volume, realize maximum membrane area, conventionally film is assembled in an elementary cell equipment with certain form, under certain driving force, complete the separation of each component in mixed liquor, this class device is called membrane module.Hollow fiber film assembly because its loading density is high, cost is relatively low, the life-span is widely applied compared with long and film good pressure-resistant performance.
Current existing column type hollow fiber membrane modular 10(as shown in Figure 1), on putamina 11, be provided with water inlet 12, produce the mouth of a river 13, air inlet 14 and concentrate floss hole 15, in putamina 11, be fixed with water inlet end resin-cast fixed bed 32 and produce water end (W.E.) resin-cast fixed bed 34, in water inlet end resin-cast fixed bed 32, be provided with a plurality of gas-liquid pod apertures 23a, produce in water end (W.E.) resin-cast fixed bed 34 and be connected with again concentrate delivery pipe 16, between water inlet end resin-cast fixed bed 32 and product water end (W.E.) resin-cast fixed bed 34, be fixed with many hollow fiber film threads 35.
Mainly there is following problems in existing hollow fiber column type membrane module:
The first, existing column type hollow fiber membrane modular is with resin, hollow fiber film thread and putamina cast to be fixed together, and causes operation inconvenience when making large-scale hollow fiber film assembly, reduces production efficiency.
The second, because the structural design of gas-liquid pod apertures in water inlet end resin-cast fixed bed is unreasonable, cause this fixed bed bulk strength to decline, unit volume amount of resin declines and has also reduced the adhesive strength between hollow fiber film thread simultaneously.
The 3rd, because being subject to the restriction of resin fixed bed intensity, gas-liquid pod apertures quantity makes the close thin inequality of hollow fiber film thread distribution, reduce hollow fiber film thread contamination resistance, affect the cleaning performance of column type hollow fiber membrane modular, reduction of service life.
The 4th, existing column type hollow fiber membrane modular is with resin, the cast of hollow fiber film thread and putamina to be fixed together, and in servicely when local hollow fiber film thread damage, can only scrap whole membrane module, causes the wasting of resources, the cost of increasing input.
