Description

A kind of self-driving type silk algae culturing device

Technical field

The utility model relates to a kind of self-driving type silk algae culture systems, belongs to field of agricultural production technologies.

Background technology

Silk algae frond is by cylindric cell be connected single-row, the filamentous of branch not that form. Silk algae (Ulothrix) Chlorophyceae, Ulotrichaceae. Frond is elongated, connects into unbranched filamentous by single-row cell. Frond is divided into upright or the part of crawling, and most of kind cell membranes are made up of complete a slice, and anterior view is H type, chromatoplast Zhousheng. Monokaryon, chloroplaset ring-band shape or tubular, contain one or more pyrenoid. Base portion is one and forms holdfast without cytochrome.

Silk algae contains vitamin and humatite matter, protein and amino acid, w3 aliphatic acid widely. In known device, comprise a certain amount of nutrient with anti-oxidant properties as chlorophyll and carrotene. Multiple research in recent years significantly shows, a silk algae for some kind has significant non-oxidizability and anti-inflammatory character. Therefore silk algae is a kind of use and the algae bio of pharmacy.

The energy is the material base of mankind's activity. Say in some sense, the development of human society be unable to do without the appearance of high-grade energy and the use of advanced energy technology. In the world today, the development of the energy, the energy and environment, be the whole world, whole mankind's questions of common interest, is also the major issue of Chinese society economic development. China is a production of energy big country and consumption big country, has abundant fossil energy resource. 2006, coal reserves was 10,345 hundred million tons, verify residual recoverable reserves account for global 13%, row third place in the world. But the owning amount of energy resources per capita of China is lower, and coal and waterpower resourses per capita owning amount are only equivalent to 50% of world average level, and oil, natural gas per capita resources owning amount are only 1/15 left and right of world average level. Energy resources tax is deposited unbalanced, and development difficulty is larger, has verified the high-grade energy such as oil, natural gas reserves wretched insufficiency. Add energy utilization technology and fall behind, utilize lowly, under the condition of fast increasing economy, the depletion rate of China's energy is faster than other countries, and the threat of lack of energy may come more early, more serious. Thereby the Pressure on Energy that growing external energy demand causes forces us to have to find the road of the breakthrough that solves energy crisis.

In sum, along with the status of energy problem in mankind's activity and social production is more and more higher, the contradiction of economic development and environmental pollution more source is sharp-pointed.

Utilize above-mentioned self-driving type silk algae culturing device to realize the method that self-driving type silk algae is cultivated, comprise the following steps:

Step 1, build self-driving type silk algae culture systems:

Utilize self-driving type silk algae culturing device of the present utility model, deposit is sieved, particle diameter is 2mm, puts into reative cell 5 after centrifugal, and the product carbon plate 3 that is connected with wire 4 is imbedded in deposit, and water is injected to reative cell 5 and water level on deposit; Quiescent settling is to the interior deposit of reative cell 5 and water stratification is obvious and water body is limpid; Because the top of reative cell 5 is upper open design, therefore, in reative cell 5, be respectively air, water, deposit from top to bottom;

Step 2, enrichment plate 6 is placed in to water, product carbon plate 3 is embedded in deposit, enrichment plate 6 can hang or float in water, by enrichment plate 6, produce carbon plate 3 and resistance or low-power electrical appliance 1 use wire 4 is together in series, and resistance or low-power electrical appliance 1 are positioned at enrichment plate 6 and produce carbon plate 3 centres; Wherein, the span of resistance is 10～2000 ohm, and the performance number of low-power electrical appliance is 1mW to 100mW;

After the power of step 3, the resistance value of determining resistance or low-power electrical appliance, static 7 days, described product carbon plate 3 hangs up anaerobic organism film, the temperature of reative cell 5 is controlled to 20～30 DEG C, the TIC content that adopts TOC instrument method to measure in water body every 5 days, described TIC content comprises carbon dioxide, the content of bicarbonate radical and carbonate;

Step 4, in the time that the TIC content in water body is increased to 40mg/l, to wait to cultivate silk algae and be inoculated in enriched layer water body according to 100-1000mg/l, be the surface of enrichment plate 6 or the interface of deposit and water, cultivation temperature is 20～30 DEG C, illumination adopts natural daylight or artificial light source, light dark period is 16h:8h, and intensity of illumination is 1500-3000ALUX, and cultivated days is 20～30 days.

Embodiment: under natural imitation water body in lake, the growing state of silk algae in self-driving type silk algae culture systems and the operation principle of culture systems.

With reference to the structure of Fig. 1, build the self-driving type electro-chemical systems that a thread algae is cultivated, by reative cell 5, the enrichment plate 6 of water and sediment, produce several parts such as carbon plate 3, wire 4, resistance 1 and form. Its reative cell 5 is that top contacts with air, and the high 15cm of all the other face closures, in the cylinder glass container of diameter 7cm. The area of enrichment plate 6 and product carbon plate 3 is 28.29cm respectively². In reative cell 5, be respectively air, water, deposit from top to bottom, and deposit there is obvious layering through sedimentation and water. Wherein deposit layer height is 5cm, and deposit layer is anaerobic environment, have multiple anaerobic bacteria to be enriched in to produce to decompose the organic matter in deposit near carbon plate, thereby making to produce carries out anaerobic digestion near carbon plate and can produce carbon dioxide, produces carbon plate and is embedded in deposit layer.
