Description

A kind of compact sewage treatment equipment

Technical field

The present invention relates to a kind of compact sewage treatment equipment.

Background technology

Marine sewage treatment system generally adopts biochemical process to be processed, through the sewage of aeration aerating with the certain flow filler of flowing through, make on filler to cover with microbial film, 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 the 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 the positive proportionlity with the device processing efficiency, so, if an independent factors vary, other are constant, when design in proportion reduction means get final product, but often when the 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, the 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 the 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 characteristics 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.

Summary of the invention

The invention provides a kind of compact sewage treatment equipment, it is low that this device has a cost, and device volume is little, lightweight, processing efficiency is high, without advantages such as routine maintenances.

The present invention has adopted following technical scheme: a kind of compact sewage treatment equipment, comprise solarization air cell, exposure chamber, settling chamber and MBR assembly, described solarization air cell is communicated with exposure chamber, described exposure chamber is communicated with settling chamber, described settling chamber is connected with the entrance end of MBR assembly by pipe connecting, the exit end of MBR assembly is connected with ultraviolet sterilization apparatus by process pump, the exit end of described ultraviolet sterilization apparatus be connected out of my cabin.

Described solarization air cell, exposure chamber and the three's of settling chamber bottom and the side-lower of solarization air cell are connected with the entrance end of macerator pump by pipeline, the macerator pump exit end returns to the upper end of solarization air cell by pipeline, pipeline between the exit end of macerator pump and solarization air cell upper end is provided with valve V5, the entrance end of described macerator pump and the bottom of solarization air cell, and the bottom of exposure chamber, and the bottom of settling chamber and and the side-lower of solarization air cell between pipeline on be respectively equipped with valve V1, valve V2, valve V3 and valve V4; Pipeline between described macerator pump and solarization air cell is provided with bleed valve valve V6; Be provided with aeration tube in described solarization air cell, exposure chamber and settling chamber, three's aeration tube is connected with blower fan by pipeline simultaneously, also is provided with air-lift device on pipeline, and described air-lift device forms loop Bing Yu solarization air cell and is communicated with in settling chamber; Aeration tube in described solarization air cell, exposure chamber and settling chamber is provided with several microporous aeration devices; Be provided with the suspension type stereoscopic filler in described solarization air cell; The side of solarization air cell is provided with sampling unit; The exit of the exit end of described ultraviolet sterilization apparatus is provided with vacuum breaker.

The present invention has following beneficial effect: it is low that the present invention has a cost, and device volume is little, lightweight, processing efficiency is high, without advantages such as routine maintenances; The present invention has simplified original MBR cell structure, only adopt a blower fan and a macerator pump simultaneously, greatly reduced space and the cost of device, microporous aeration device has been installed on aeration tube and has not only been reduced the length while of whole aeration tube but also improved overall treatment efficiency.
