Description
Technical field: the present invention relates to a kind of sewage microalgae biomembrane purification system, especially a kind of with in Aeration tank, pass through microalgae, by organic by nano biological membranous system in sewage, under conditions of photosynthesis, complete organic matter degradation and microdisk electrode dirty, the algae of output as biomass energy again with, whole process can realize biogas and pyrolysis gas recycling, belongs to field of environmental technology.
Background technology: Organic Chemical Plant and organic additive factory are in occupation of consequence in petrochemical enterprise, and its product is mainly chemical reagent, chemical industry intermediate products, or the monomer of production synthetic material, indispensable on petrochemicals chain.This kind of high-concentration organic chemical-industrial sewage water quality is complicated, pollutant kind is many, the COD content of sewage high (most up to thousand of to tens0000), pH value changes greatly, and intermittent discharge, change of water quality is big, it is difficult to directly use single materialization or biochemical technology to process, and this high-concentration organic chemical-industrial sewage is mixed in oil refining sewerage always and handles together or process in the way of concentrating outward transport by petroleum chemical enterprise.
Summary of the invention: for the shortcoming of above-mentioned prior art, the invention provides a kind of organic chemical industry sewage that can process and can cultivate again microalgae sewage ecological treatment system in the airtight nano biological film of microalgae.
For achieving the above object, the technical solution used in the present invention is: microalgae sewage ecological treatment system in airtight nano biological film, including airtight microalgae culture system, microalgae separator, microalgae one-level catcher, circulating pump, the first valve, two grades of catchers of microalgae, air vent, the second valve, Aeration tank.Airtight microalgae culture system is the elliptical ring that nano biological film surrounds, and it is in Aeration tank, and its one end connects microalgae separator by the first valve, and the other end is connected with circulating pump by the second valve.Microalgae separator is dual circuit mechanism, and its pipeline one connects following microalgae one-level catcher, and pipeline two connects with air vent.The lower end of microalgae one-level catcher is thicker than upper end, and the two grades of catchers in its lower end and microalgae are connected.The upper end of microalgae one-level catcher is connected with airtight microalgae culture system by circulating pump and the second valve.
Present configuration is simple, it is easy to accomplish, it has suffered Cheng Shixian the dirty water decontamination handles, promote again breeding and the growth of diatom in water ecosystem, form new biomass energy.
Accompanying drawing illustrates:
Fig. 1 is the structural representation of the present invention.
As shown in Figure 1: microalgae sewage ecological treatment system in airtight nano biological film, including airtight microalgae culture system 2, microalgae separator 3, microalgae one-level catcher 4, circulating pump the 5, first valve 9, two grades of catchers 7 of microalgae, air vent the 8, second valve 6, Aeration tank 10.Airtight microalgae culture system 2 is the elliptical ring that nano biological film 1 surrounds, and it is in Aeration tank 10, and its one end connects microalgae separator 3 by the first valve 9, and the other end is connected with circulating pump 5 by the second valve 6.Microalgae separator 3 is dual circuit mechanism, and its pipeline one connects following microalgae one-level catcher 4, and pipeline two connects with air vent 8.The lower end of microalgae one-level catcher 4 is thicker than upper end, and the two grades of catchers 7 in its lower end and microalgae are connected.The upper end of microalgae one-level catcher 4 is connected with airtight microalgae culture system 2 by circulating pump 5 and the second valve 6.
Each component function:
1, nano biological film: the biomembrane of a kind of nano molecular structure, can allow the organic matter in water body and carbon dioxide enter in airtight microalgae culture system, and microalgae can not film out.
2, airtight microalgae culture system: carry out the system of microdisk electrode in nano biological film.
3, microalgae separator: microalgae separator is dual circuit mechanism, the together following microalgae one-level catcher link of its pipeline, pipeline two links with air vent, it is therefore an objective to get rid of the microalgae absorption of output oxygen on microalgae surface in incubation.
4, microalgae one-level catcher: it is thick that microalgae one-level catcher presents lower body, upper body straight tube designs, it is therefore an objective to realizing microalgae enrichment presented below, the microalgae of high concentration exists microalgae one-level catcher bottom.
5, circulating pump: microalgae relatively low for the concentration on microalgae one-level catcher top is pumped into back in airtight microalgae culture system as microalgae " seed ".
6, the second valve: the microalgae that the concentration on control microalgae one-level catcher top is relatively low flows back in airtight microalgae culture system with the help of circulating pump again as microalgae " seed ".
7, two grades of catchers of microalgae: the collection device that microalgae is final, by twice enrichment, it is thus achieved that high concentration microalgae；
8, air vent: get rid of microalgae device of the absorption of the output oxygen on microalgae surface in incubation；
9, the first valve: control when algal grown is ripe, when quantity is more, allows cultured algae solution flow into the valve of microalgae separator.
10, Aeration tank: the reaction tank that sewage aerobic processes.
Workflow:
1, in Aeration tank 10, in airtight microalgae culture system 2, microdisk electrode is carried out, organic matter in Aeration tank 10 and utilized the carbon dioxide of institute's output to enter airtight microalgae culture system 2 by nano biological film 1 after aeration by microorganism by nano biological film 1；
2, completing photosynthesis under the effect of illumination, microalgae absorbs the organic matter in the sewage being entered airtight microalgae culture system 2 by nano biological film 1 and carbon dioxide, completes algal grown；
3, ripe when algal grown, when quantity is more, open the first valve 9, allow cultured algae solution flow into microalgae separator 3；
4, microalgae separator 3 is dual circuit mechanism, and its pipeline together following microalgae one-level catcher 4 links, and pipeline two links with air vent 8, it is therefore an objective to get rid of the microalgae absorption of output oxygen on microalgae surface in incubation；
5, to present lower body thick for microalgae one-level catcher 4, upper body straight tube design, it is therefore an objective to realizing microalgae enrichment presented below, the microalgae of high concentration exists microalgae one-level catcher 4 bottom, microalgae after enrichment enters two grades of catchers of microalgae 7 and carries out secondary enrichment, it is simple to results high concentration microalgae；
6, the microalgae that the concentration on microalgae one-level catcher 4 top is relatively low is as microalgae " seed " by opening the second valve 6, again flows back in airtight microalgae culture system 2 with the help of circulating pump 5, and in starting the airtight nano biological film of a new round, microalgae sewage is cultivated.
