Description

A kind of small-sized domestic sewage treatment device

Technical field

The utility model relates to a kind of small-sized domestic sewage treatment device.

Background technology

Marine sewage treatment system generally adopts biochemical process to process, through the sewage of aeration aerating with the certain flow filler of flowing through, make to cover with microbial film on filler, sewage contacts with microbial film, under biomembranous effect, thereby aerobic bacteria is constantly engulfed organism sewage is purified.But often device is larger, and the sewage of discharge more meets emission request, particularly packaged unit, it is not up to standard that the scaled down version of employing large-scale plant is often discharged detection.

In sewage disposal flow process, there are several key factors to need to consider, it rushes the utilization ratio that oxygen ability, oxygen leave efficiency and oxygen, biofilm formation and treatment effect, return sludge ratio, ultraviolet ray virus killing rate, and membrane filtration etc. is to weigh sewage treatment unit to process the most important Consideration of index, particularly on the packaged unit below 10 people, with respect to other medium-and-large-sized sewage treatment units, it rushes the utilization ratio that oxygen ability, oxygen leave efficiency and oxygen, and biofilm formation and treatment effect, be major consideration; Because these indexs are when design calculation, all to become positive proportionlity with device processing efficiency, so, if an independent factors vary, other are constant, in when design reduction means in proportion, but often when small design device, these indexs change, and be all to dwindle on year-on-year basis, therefore, its treatment effect is difficult to assurance, and this is also that these packaged units are processed principal element not up to standard in the market.

In waste disposal plant, general consider be 60 people and above minimum be also more than 10 people, in the design of the sewage treatment unit below small-sized 10 people of inner water transport boats and ships, it is almost the sewage treatment unit that dwindles plate, diminishing along with plant bulk like this, oxygen and sewage are short duration of contact, aeration effect reduces, the mass transfer rate of oxygen reduces, the molten rate of oxygen reduces, the utilising efficiency of oxygen decreases with the biomembranous effect that contacts with aerobic bacteria, Biochemical Treatment also reduces greatly, cause chain negative effect, therefore in the water of discharge detects, it is qualified to be difficult to, if according to 159(55) it is provided by resolution that discharge water quality requirement, certainly will cause that low, the biochemical time of waste disposal plant handling property is elongated, machine volume is large, working cost is high, yet the feature of small-sized inland navigation craft, to the requirement of the equipment such as waste disposal plant be that volume is less, weight is lighter, processing efficiency is high, without routine maintenance, thereby all limited use range and the effect of waste disposal plant.
