Specific embodiment

It is further introduced, but is not intended to limit below in conjunction with some embodiments of the attached drawing to the utility model The protection scope of the utility model.

Referring to Fig. 1, a kind of biological sewage treatment device with lautertuns according to the present utility model, including saprobia Processing equipment 1, lautertuns 3 and conditioning tank 5, the wastewater inlet 11 and conditioning tank 5 of the Sewage Biological Treatment equipment 1 pass through sewage Pipe 41 is in fluid communication, and carries out Sewage Biological Treatment for the sewage in conditioning tank 5 to be imported Sewage Biological Treatment equipment 1 to obtain First water purification, and the first valve 21 and sewage pump 13 are additionally provided on sewage pipe 41, for according to sewage water and water quality adjustment into Enter the discharge of sewage of Sewage Biological Treatment equipment 1, and thus controls the water quality and water of the first water purification.In general, the water inlet of sewage Measure smaller, the water of the first water purification is with regard to smaller, but water quality can be better.The biological sewage treatment device can be any appropriate Biological sewage treatment device well known in the prior art, for example, CN102372396A, CN102372360A, CN102557326B, Disclosed in CN102372397B, CN103523920B those.

The lautertuns water inlet of first water purification outlet 12 and 3 lower end of lautertuns of the Sewage Biological Treatment equipment 1 31 are in fluid communication by the first pure water pipe 43 for first water purification importing lautertuns 3 to be filtered processing to obtain The second water purification is obtained, second water purification is discharged by the second pure water pipe 45 for the second water purification outlet 33 of 3 upper end of lautertuns. For example, in sewage disposal process, the short time of having to sometimes increase enter the discharge of sewage of Sewage Biological Treatment equipment 1 with Just the sewage temporarily more than its processing capacity is handled in time, thus may cause and carries excessive sludge in the first water purification secretly, this When the first water purification is filtered processing by lautertuns 31 can effectively filter out excessive sludge, thus obtain it is qualified Second water purification.

First water purification outlet 12 also passes through the back-flushing water inlet of back-flushing water inlet pipe 44 and 3 upper end of lautertuns 32 are in fluid communication and carry out backwash processing for first water purification to be imported the lautertuns 3,3 lower end of lautertuns it is anti- The backwash for being discharged after handling backwash is in fluid communication by recoil water discharge pipe 42 and conditioning tank 5 for bath water outlet 36 It handles water and imports conditioning tank 5.Lautertuns 3 is carried out with the common clear water generated using additional clear water or other filter devices Backwash is different, and the utility model is directly backwashed using the first water purification of high quality, thus avoids conventional using clear The trouble that water is backwashed.It is smaller in the discharge of sewage that first water purification of the high quality can be Sewage Biological Treatment equipment 1 And pollutant it is less in the case where the first water purification for producing.

In some cases, the position of first water purification outlet 12 is higher than the outlet port of the second pure water pipe 45, described The position of back-flushing water outlet 36 be higher than conditioning tank 5 the water surface, thus can merely with the flowing of the first water purification of gravity drive with into Row filtering and backwash processing.

The lautertuns 3 includes vertical tubular tank body, and the water distributing plate 34 being set in tank body lower part is set to cloth in tank body 34 top of water plate gathers materials, and the lautertuns water inlet 31 and back-flushing water outlet 36 are located on the tank body of 34 lower section of water distributing plate, The back-flushing water inlet 32 and the second water purification outlet 33 are located on the tank body for the top that gathers materials.

In some cases, the second valve 22 and the second water purification when carrying out the filtration treatment, on the first pure water pipe 43 The 4th valve 24 on pipe 45 is in the open state, and the third valve 23 on back-flushing water inlet pipe 44 and recoil water discharge pipe 42 On the 5th valve 25 be in close state；When carrying out the backwash and handling, the second valve 22 on the first pure water pipe 43 and the The 4th valve 24 on two pure water pipes 45 is in close state, and third valve 23 and back-flushing discharge on back-flushing water inlet pipe 44 The 5th valve 25 on pipe 42 is in the open state.

In some cases, described to gather materials for quartz sand or river sand, including the granularity 16- being successively laid with from the bottom up The first of 32mm gather materials, second the gathering materials of granularity 8-16mm, the 4th collection that the third of granularity 4-8mm is gathered materials with granularity 2-4mm Material.The height gathered materials is 1200-1600mm, wherein the first height gathered materials is 300-400mm, the second height gathered materials For 300-400mm, the height that third is gathered materials is 300-400, and the 4th height gathered materials is 300-400mm.

The biological sewage treatment device with lautertuns of the utility model can be adjusted according to sewage quality and water Save the residence time of Sewage Biological Treatment equipment；Sewage water it is larger or water quality is poor (pollution level is higher, pollutant compared with It is more) when, can by not completely clear first water purification by the lautertuns water inlet of lautertuns lower end import in lautertuns into Processing capacity of the row filtration treatment so as to improve entire sewage-treatment plant and upper end in lautertuns obtain qualified the of water quality Two water purifications；And can or water quality smaller in sewage water preferably (pollution level is lower, and pollutant is less) when, conjunction will be clarified completely First water purification of lattice is imported in lautertuns backwash handling by the back-flushing water inlet of lautertuns upper end and be cleaned with this Filter pocket.

In some cases, as shown in Figures 2 and 3, the water distributing plate 34 is equipped with multiple water distributing pores 341, in the cloth Cloth water cap 6 is equipped at each water distributing pore 341 in the upside of water plate 34, the side wall of the cloth water cap 6 has multiple first openings 61 simultaneously And roof has the second opening 62.For example, first opening 61 can there are four, be symmetrically dispersed in four sides of cloth water cap 6. In some cases, the cylinder of upper end closed can be cut out into four sides along axial direction to form four first openings 61, and It is open to form the second opening 62 in upper center.For any water distributing pore 341,5 water distributing pores of total of cloth water cap 6 can be effective Reduce flow resistance and avoids blocking.Therefore, above-mentioned cloth water cap 6 can be effectively prevented the sludge to gather materials in the first water purification Water distributing pore 341 is blocked, to reduce resistance when filtration treatment and backwash processing, is particularly conducive to merely with gravity drive the One water purification is filtered processing and backwash processing.The utility model have it is safe and reliable, adaptable, at low cost, be not easy to block up Plug is easy the advantages that dismounting and cleaning, thus becomes particularly suitable for small sewage biological processing unit in sewage water and water quality Change the application in biggish situation.

The utility model is described above by the mode of illustration.It is understood, however, that the utility model is never only It is only limitted to these specific embodiments.Those of ordinary skill can carry out various modifications or change to the utility model, and these Modification and variation belong to the protection scope of the utility model.
