In order to determine the feasibility of the utility model apparatus system, the applicant has carried out on-the-spot back yard industry test.By complex art economic analysis and test, the utility model is determined to adopt mechanical accelerating purifying pool+change fracture filtration+immersion ultrafiltration+reverse osmosis scheme, and main excellent characteristics are as follows:
(1) the complete anti impulsion load of technical process
The utility model adopts domestic S774 mechanical accelerating purifying pool commonly used, the turbidity allowed band 1000～5000mg/L of water inlet, upflow velocity 2mm/s.Submerged ultrafiltration is the hollow-fibre membrane of current ecto-entad, this means that film inside has only totally, passes through through the current of ultrafiltration.And bacterium in the former water and suspended substance still rest on the outside of film, so the risk that water purification current channel is not blocked and pollutes by suspended solid.
(2) operation pressure is low
Ultra-filtration membrane is to be immersed in the very little negative pressure of employing in the water to suck water outlet, working pressure be-0.014～-0.07MPa between.Under this working conditions, the energy consumption of pump is also less relatively.General pressure type ultrafiltration operates in 0.2～0.3MPa.
(3) technological operation is safeguarded simple
Entire treatment is the operation of a single step, and ultrafiltration system does not need to add other chemical agents, only need just can guarantee the good operation of ultrafiltration system and ultra-filtration membrane by safeguarding the operation that sees through liquid pump and gas blower.
(4) pipelining is convenient
This project engineering adopts the hole pattern Steel-plastic pipeline, and the site welding easy construction is anticorrosive strong, directly lays with burying.
Anti impulsion load, operation pressure are low so the utility model apparatus system has, simple, pipelining advantage is easily safeguarded in technological operation, suit energy-saving and cost-reducing at present overall situation trend more, more are applicable to the present situation of electric power plant circulating water reuse.
Compared with prior art, the utility model adopts mechanical accelerating purifying pool+change fracture filtration+immersion ultrafiltration+reverse osmosis unit system, have advantages such as anti impulsion load, operation pressure is low, the technological operation maintenance is simple, pipelining is convenient, help the recycling of electric power plant circulating water, suit current energy-saving and cost-reducing development trend more, effectively promoted the cyclically utilizing of water resources.
