Description

The one way of life waste disposal plant

Technical field

The present invention relates to the one way of life waste disposal plant.

Background technology

Marine sewage treatment system generally adopts biochemical process to process, namely through the sewage of aeration aerating with the certain flow filler of flowing through, make and cover with microbial film on filler, sewage contacts with microbial film, and under biomembranous effect, thereby aerobic bacteria is constantly engulfed organism sewage is purified, in above-mentioned sewage disposal flow process, consider seldom or specialty not for the design of aeration effect, however the aeration effect for the breeding of aerobic bacteria, and Biofilm formation has very large effect.If oxygen concn is low, suppress the breeding of aerobic bacteria, thereby aerobic bacteria is just few, the microbial film of formation is just few, it is had a liking for the organism that falls and just lacks (organic decomposition is just few), same organic content, the time of decomposition is just long, or, under the certain hour prerequisite, organic decomposition amount is just few, and in the water of discharging like this, organic content is higher, can increase the weight of and destroy natural purification process and original eubiosis of water surrounding; The algae excessive Growth and reproduction appears in body eutrophication; Grow and propagate disease to the harm of human health, and animals and plants existence is threatened; At present, on market, the biofilm formation carrier adopts many-sided ball (ring) mostly, and hollow ball (ring) also has some to adopt the honeycomb filler, and material mostly is nylon, and shortcoming is: 1, fill up two exposure chambers, requirement is large, if do not fill up, contacts effect bad; 2, manufacturing process is complicated, and cost is high; 3, easily pile up waste residue, be unfavorable for biomembranous growth; 4, contact area is little, is unfavorable for oxygen and the microbial film uniform effect in sewage; 5, the oxygen adsorption plane is little when aeration, and coefficient of oxygen utilization is low.

Summary of the invention

For the deficiencies in the prior art, the invention provides a kind of low-cost and high-performance sewage treatment unit, it is low that this device has a cost, and device volume is little, lightweight, processing efficiency is high, need not the advantages such as routine maintenance.

the present invention is by the following technical solutions: the one way of life waste disposal plant, comprise solarization air cell, the exposure chamber, settling chamber and MBR chamber, solarization air cell is communicated with by filtering sieve plate with the exposure chamber, the exposure chamber is connected with the settling chamber by the screen plate, the settling chamber communicates with the MBR chamber, at the indoor membrane module that is provided with of MBR, the outlet of membrane module is connected with ultraviolet sterilization apparatus by suction pump, the outlet of described ultraviolet sterilization apparatus device be connected out of my cabin, described solarization air cell and exposure chamber are connected with air pump, be provided with suspension stereo structure filler in described exposure chamber, this suspension stereo structure filler is comprised of axial cord and silk hair, described silk hair is the stereo structure homogeneous radiation in the surrounding of axial cord.

Described silk hair is nylon wire drawing silk hair, and the diameter of silk hair is 150-200mm; Described solarization air cell, exposure chamber, settling chamber and MBR chamber are connected with the entrance end of macerator pump, the macerator pump exit end returns to 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; Described MBR chamber forms by flushing pump and settling chamber the loop of recoiling; Described solarization air cell and exposure chamber are connected with air pump; Air pump by air-lift device respectively in the settling chamber and MBR indoor formation loop and being 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 be provided with in the exposure chamber suspension stereo structure filling-material structure make this filler in the exposure chamber inner comprehensive unfold uniform.
