Description
Technical field
The present invention relates to a kind of sewage treatment unit.
Background technology
At present, known marine sewage treatment system adopts biochemical process to handle substantially, promptly through the sewage of oxygenation with the certain speed filler of flowing through, make and cover with microbial film on the filler, sewage contacts with microbial film, under biomembranous effect, thereby aerobic bacteria is constantly engulfed organism sewage is purified.
Owing to " the MARPOL73/78 pollution convention " that emission request proposed about the Sewage from Ships treatment unit that pass through on October 13rd, 2006 from Marine Environmental Protection Committee of formal enforcement on January 1st, 2010 International Maritime Organizaton; the discharge index of original device sewage disposal flow process far can not satisfy the new sewage drainage standard that new " pact " announced; and conventional device is short work-ing life, and cleaning is inconvenient.
| Former discharge index | New pact discharging | |
| Coliform (M.P.N) is put down for how much | ≤ 250/100mL | ≤ 100 |
| How much of suspended solids total amounts (S.S) | ??≤50mg/L | ??≤35mg/L |
| Five-day BOD (BOD5) | ??≤50mg/L | ??≤25mg/L |
| Chemical oxygen demand (COD) (COD) | ??≤125mg/L | ??≤125mg/L |
| PH value | ??6-9 | ??6-8.5 |
Summary of the invention
At the deficiencies in the prior art, the invention provides a kind of low-cost and high-performance sewage treatment unit, can satisfy the discharge index of new " pact ", and cost is low, long service life.
The present invention is by the following technical solutions: a kind of sewage treatment unit, comprise solarization air cell, exposure chamber, settling chamber and MBR chamber, described solarization air cell is communicated with by filtering sieve plate with the exposure chamber, described exposure chamber is connected with the settling chamber by filter bag, described settling chamber communicates with the MBR chamber by rejecting pump, the indoor membrane module that is provided with of described MBR, the outlet of membrane module is connected with ultraviolet sterilization apparatus by suction pump, the outlet of described ultraviolet sterilization apparatus device with link to each other out of my cabin.
Described solarization air cell, exposure chamber, settling chamber and MBR chamber link to each other with the entrance end of macerator pump, the macerator pump exit end returns solarization air cell, be provided with valve V5 between the exit end of macerator pump and solarization air cell, be respectively equipped with valve V1, valve V2, valve V3 and valve V5 between described macerator pump entrance end and solarization air cell, exposure chamber, settling chamber and MBR chamber; Be provided with emergency venting valve valve V6 between described macerator pump and solarization air cell; Water pressure tank and filter bag form the recoil loop; Described solarization air cell and exposure chamber link to each other with air pump; Air pump by air-lift device respectively in the settling chamber and MBR indoor formation loop and be communicated with solarization air cell; The exit of described ultraviolet sterilization apparatus is provided with vacuum breaker.
The present invention has following beneficial effect: the present invention is except that all advantages of continuity biochemical process waste disposal plant, and former marine sewage treatment plant upgraded, to adapt to the new demand that new " pact " formulated sewage drainage standard peculiar to vessel, filter bag, MBR assembly and apparatus for ultraviolet disinfection have been added especially.The filter bag that increases has the function of back flushing, can prolong the work-ing life of filter bag, and backwash operation is simple and easy.But MBR assembly life-time service need not to change, and discharging water quality is not exceeded standard.
Description of drawings
Fig. 1 is a structural representation of the present invention
Embodiment
In Fig. 1, a kind of sewage treatment unit comprises solarization air cell 1, exposure chamber 2, settling chamber 3 and MBR chamber 4, and solarization air cell 1 is communicated with by filtering sieve plate 5 with exposure chamber 2, exposure chamber 2 is connected with settling chamber 3 by filter bag 11, and water pressure tank and filter bag 11 form the recoil loop.Settling chamber 3 communicates with MBR chamber 4 by rejecting pump 9, be provided with membrane module 6 in the MBR chamber 4, the outlet of membrane module 6 is connected with ultraviolet sterilization apparatus 8 by suction pump 7, the outlet of ultraviolet sterilization apparatus 8 device with link to each other out of my cabin, the exit of ultraviolet sterilization apparatus 8 is provided with vacuum breaker 15.Solarization air cell 1, exposure chamber 2, settling chamber 3 and MBR chamber 4 link to each other with the entrance end of macerator pump 10, macerator pump 10 exit end return solarization air cell 1,1 of the exit end of macerator pump 10 and solarization air cell are provided with valve V5, described macerator pump 10 entrance ends and solarization air cell 1, exposure chamber 2, settling chamber 3 and 4 of MBR chambers are respectively equipped with valve V1, valve V2, valve V3 and valve V5, and 1 of macerator pump 10 and solarization air cell are provided with emergency venting valve valve V6.Solarization air cell 1 and exposure chamber 2 link to each other with air pump 12, and air pump 13 forms the loop respectively by air-lift device 14 and is communicated with solarization air cell 1 in settling chamber 3 and MBR chamber 4.
Principle of work of the present invention is as follows: along with constantly entering of sanitary sewage, macerator pump provides signal by the time relay, regularly, after liquid level reach a certain height, understand, flow automatically in the exposure chamber by the filtration sieve plate between solarization air cell and the exposure chamber to pulverizings that circulate repeatedly of the sewage in the chamber.Be hung with filler in the exposure chamber, and give birth to full microbial film on the filler, aeration waste water is when flowing through microbial film, and organic substance is cleared up into carbonic acid gas and water.Sewage after the exposure chamber handles can guarantee that the sewage that enters into the settling chamber does not contain the above suspended substance of 50um through the special filter bag of diagram.When the liquid level in the settling chamber attains to a high place electrode, reject pump and start automatically, the water in the settling chamber is rejected to the MBR chamber, when liquid level is reduced to low position electrode, reject pump and stop automatically.When the indoor water level of MBR attains to a high place, suction pump and apparatus for ultraviolet disinfection start, and this indoor water is sucked up to the apparatus for ultraviolet disinfection sterilization after can filtering through the MBR assembly, water water quality after sterilization can reach new sewage drainage standard, then is excluded outboard.During works better, valve V1 and V5 often open, and valve V2, V3, V4, V5 are normally closed, use when maybe needing to clear up when device suspends, can close by V5, and other valve wide opens, starting macerator pump can be with the whole emptying of the sewage in each chamber.
