Description
Technical field
The utility model relates to a kind of improvement of micro-electrolysis device of the surface active agent wastewater of handling high density, difficult degradation, especially relates to the improvement of water distribution, gas distribution facility and filler type of feed.
Background technology
Micro-electrolysis method claims internal electrolysis again, is that multiple physics, chemical actions such as a kind of current collection solution, coagulation, electricity flocculation, absorption are in the method for wastewater treatment of one.By the noble potential of iron filings iron in the aqueous solution with wherein form potential difference between the low spot position of charcoal, produce countless small galvanic cells, nascent state H, Fe that electrode reaction generates
2+Have stronger reducing power, can make the ring-type of difficult degradation or have the organic pollutant chain rupture of unsaturated link(age), generate the organism of phase commute degraded, thereby can remove coloring matter and Persistent organic pollutants in the waste water water well.Iron loses the nascent state Fe that produces behind the electronics
2+Have higher absorption coagulation activity, can remove organic pollutant and colloidalmaterial in the waste water effectively.
Above-mentioned principle as can be known, micro-electrolysis method is fine for the treatment of the used water difficult to degradate effect, but because there is defective in existing micro-electrolysis device at aspects such as water distribution, gas distribution facility and filler types of feed, cause the easily passivation in actual motion of used micro-electrolysis stuffing, harden, have a strong impact on treatment effect and the cycle of operation.
CN201144169Y relates to the vertical micro-electrolysis device of a kind of sealing, formed by intake zone, reaction zone, disengaging zone, froth breaking district, from going up arranged in series down, be column-shaped barrel, intake zone and reaction zone are separated by air distribution plate, reaction zone is connected by flange seal with the disengaging zone, and the disengaging zone communicates with the froth breaking district is middle, is tightly connected all around; The intake zone bottom is provided with sewage import and compressed air inlet; Reaction zone is in series by a joint or the identical reaction column of multi-section structure, and each saves and fills iron filings and particle charcoal in the reaction column, and each saves reaction column and connects by flange seal, between the flange seal circle sieve grate is housed; Avris below, disengaging zone is provided with the water outlet overflow port; The froth breaking district establishes the foam overflow weir, and overflow weir top or bottom outside are provided with overflow port.Though at device initial operating stage processing efficiency height; but the operation along with device; adhesion in various degree can take place in easy formation channel and iron filings and carbon granules gradually in the reactor; cause that stopping composition hardens, passivation, processing efficiency obviously descends, and whole bed laminate knot together when serious; processing efficiency sharply descends and equipment can not normally be moved; and when changing stopping composition, need the dismounting flange, the manual operation amount is very big.
