Description
Technical field
The invention belongs to technical field of waste water processing, relate to a kind of parts of industrial high salinity sewage treatment equipment, be specifically related to a kind of non-stop layer rod-pulling type anti-high pressure anti-pollution type high salinity filter membrane post.
Background technology
Along with China's industrialization degree is more and more higher, the discharge capacity of the industrial wastewater containing large amount of organic and inorganic salts is also increasing, huge harm is caused to ecological environment, accelerates the scarcity of water resource especially, become the serious restraining factors to social economy's sustainable development.In the face of form severe like this, the discharge standard of China to industrial wastewater is more and more higher, even requires industrial wastewater " zero-emission ", requires that enterprise realizes industrial wastewater fully recovering as far as possible.
Current domestic widely used technology for treating industrial waste water bag mainly comprises nanofiltration (NF), counter-infiltration (RO) membrane technology, the highest general pressure-bearing is about 80 kgfs, the most highly enriched waste water is 5 ~ 60,000 ppm salt content, and the saturated concentration (23 ~ 30%) of this concentration distance salt evaporative crystallization also has very large distance.That is the Waste water concentrating more than 60,000 salt content is mainly by the evaporation of power consumption, so how to reduce the salt content of concentrated liquid measure and raising concentrate further, reduce the energy consumption of evaporative crystallization link, be the research and development direction of Industrial Wastewater Treatment always.The technological difficulties of industrial wastewater " zero-emission " system are just the process of industrial high salinity waste water to comprise coal chemical industrial waste water, power plant desulfurization waste water, metallurgical waste water etc.Dish periosteum (DT membrane, US5069789) and its renewal product ductwork type film (ST membrane, US2004/015971 A1) of the development of ROCHEM company of Germany may be used for processing industrial high salinity waste water.But be dish periosteum or ductwork type film all have oneself defect when processing hc effluent.Such as: the effective film area of dish periosteum only has 8 ~ 9m2, the floor space of set of system is usually huger.And ductwork type film is dish periosteum develops when generally applying on German market, 3 ~ 4 times of its major advantage to be the effective film area of single ductwork type film be single dish periosteum effective area.But in order to original dish periosteum directly can be replaced, ductwork type film remains the center pull rod (as Fig. 1) of dish periosteum, the existence of center pull rod makes ductwork type film can not standard putamina in application market, thus involves great expense, and decreases the effective film area of single film.And in China, dish periosteum is commercially applied and immature, when processing industrial wastewater, directly can apply ductwork type film, therefore also just there is no need to retain its center pull rod.And the sealing ring at putamina two ends, when practical application, when pressure is higher than 70 kgf, is very easily extruded, is caused equipment to leak by existing dish periosteum and network pipe type film on market, cannot normal operating.
