【正文】 minations according to the different craft request the fit water is tradition oxidizes the ditch pushes to flow is to make use of to turn to brush, turn a disc or pour the umbrella type form machine realizes of, its equipments utilization is low, the motive consumes bore spirit type Carrousel 2000 systems then adopted the underwater pushes the way that flow, rises to dive the propeller the leaf the motivation that round creation the direct function namely in the of water, at push to flow the function to can keep dirty mire from sinking to decline effectively again at the same a result, the adoption dives the propeller since lower the motive consume, making mire water got again to mixs with adequately. Carrousel 3000 system Carrousel 3000 systems are in the Carrousel 2000 systems are exto plus a living creature the choice the living creature choice area is a craft to make use of high organism carries to sieve germ grow, repress silk form germ increase, increase each pollutant do away with the rate, afterward principle together Carrousel 2000 syste m. Carrousel 3000 system of bigger increases to express at:An is to increased the pond deep, can amount to 39。530 oxidize the ditch water the deep(~ ms) paring, turn to brush occupied the deep 1 / 1 0~ in water 1/12, turned the dish to also occupy the 1/639。1f discover the dirty mire is corrupt, should enlargement tolerance, the clearance accumulates the mire, and try the ameliorative pond internal water dint term!39。Moreover, contain the oil in the waste water? Take place thedirtymire ascendafterfloating should pauseenter water, broke off or dirty mire in clearance, judge the clear reason, adjust the dirty mire sinks to decline the sex bad, can throw to add of oagulate or sloth materials, the improvement precipitates the sex。t like to control very much in operate process its at two sink the pond stop over time, resulting in the anoxia easily, producing the corrupt and dirty mire ascend to float。t pletely and availably its obviation, parts of greases enriches to gather in in the dirty mire, through turn to brush the oxygen agitation, creation large quantity foam。At the same time, the ammonia were too oxidized nitrate with second nitrate, this time, mix with the liquid be placed in the oxygen the spirit machine downstream, after water current be bee by the swift flow appearance of the spirit District oP even flow the appearance, the water current maintainsin theminim umcurrentvelocity,guaranteeingthe liveand dirty mire be placed in the floats the appearance.( average current msl s)Oxldlze microbially the process consumed to fuse theoxygenin thewater,until thevalueofDOdeclinesforzero, mixing with the liquid report the anoxia nitric that turn the function through anoxia area, mix with the liquid enter to have the oxygen area, pleting once system inside, the BOD declines the solution is a continuous process, the nitric turns the function to turn with the versa nitric ~e function ta ke place in same of structural restrict, this kind of oxidize the ditch although can then valid whereabouts BOD, divided by the phosphorus take off the nitrogenous ability ltmrtedt. The Carrousel oxidizes the ditch divideds by the phosphorus takes off the nitrogenous influence factor. Affecting the Carrousel oxidizes the ditch divideds by the phosphoric factor is dirty mire, nitrate density and quality densities research expresses, being total and dirty mire as 11% that a hour biggest phosphorus 4% with deal is its fuck dirty mire deal within live and dirty mire, keep for the the germ physical endowment measures, but when dirty mire over 15 d hour dirty mire the Inside is biggesttocontain theobviousdescentindealIn phosphorus,canning not reach the biggest divideding by the result of phosphorus on the , prolong persistently the dirty mire (for example 20ds,25ds,30ds) is to have no necessary, proper choose to use within the scope of 8~ 15 the same time, high nitrate density with low quality density disadvantage in divided by the process of phosphorus . 4. The Carrousel oxidizes problem and solution methods of the ditch esse. Though the Carrousel oxidizes the ditch has a water fluid matter good, the antipounds at the burthen ability strong, divided by the phosphorus take off the nitrogen efficiency. But, in physically of movement process, still exstts a series of problem. Dirty mire inflation problem When discard the aquatic carbohydrate more, the N, P contains the unbalance of deal, the pH value is low, oxidizing the dirty mire in inside in ditch carries high, fuse the oxygen density the shortage, line up the mire not etc. causes easily dirty mire in germ in form in silk inflatlon。原污水→粗格柵→污水提升泵房→細格柵→沉砂池→厭氧池→缺氧池 好氧池→二沉池→接觸池→排放 英文翻譯Oxidize the ditch craft in dirty water handle of application and development CaiZhi一jun(Foshan City Shunde District Environmental EngineeringBranch Foshan Guangdong 528000)【Abstract】Setanaerobic, naoxic section Carrous oxidation ditch with biologicla nitrogen and phosphoru sremoval capabilitie, is curren dythe mainstream of city life process of sewage treatment, This article descirbes the structure of Carrousel oxidation ditch, porcess and design problems during the operation and the corresponding solutions．【Keywords】Carrousel；Oxidationditch；Phosphorusnadnitrogenremoval；Structure；Mechanism1. Foreword Oxidize the ditch( oxidation ditch) again a continuous circulation spirit pond( Continuous loop reactor), is a live and dirty mire method a kind of to the dirty water in ditch handles the craft be researched to manufacture by the hygiene engineering graduateschool of Holland in the 5039。針對以上特點，以及出水要求，以采用生化處理最為經(jīng)濟。兩種工藝經(jīng)過比較，本項目污水處理的特點為： 污水以有機污染為主，BOD/COD = 〉，可生化性比較好，重金屬及其他的難以生物降解的有毒有害污染物一般不超標(biāo)； 污水中主要污染物指標(biāo)BOD、COD、SS值為典型城市污水值。本課題選擇典型的工藝流程，有兩種可供選擇的工藝：1）普通A/A/O法處理工藝。由于氮磷超標(biāo)，處理工藝尚用硝化除磷。三、本次設(shè)計工藝流程的選擇及分析本項目污水處理的特點：（1）本次設(shè)計主要處理城鎮(zhèn)生活污水，污水以有機污染物為主，BOD/COD= 可生化性好；（2）重金屬
