Description
Technical field
The utility model relates to a kind of device of removing wawter bloom algae microcystic aeruginosa, can be used for the removal of microcystic aeruginosa in wawter bloom or the eutrophication water.
Background technology
Along with growth and the development of industry and agriculture of urban population, the body eutrophication problem that is caused by various discharge of wastewater becomes increasingly conspicuous, and eutrophication has in various degree appearred in some lake of China.Body eutrophication causes various harmful algaes such as a large amount of breedings such as microcystic aeruginosa, anabena, and the algae pollution disaster is on the rise.The unusual breeding growth of algae, not only havoc water landscape and aquatic ecosystem in a healthy and balanced way, and discharge the algae toxin of number of different types behind the poisonous blue-green algae cell rupture in the water body, bring very big harm for human health, hydrocoles, poultry etc.
Microcystic aeruginosa is one of modal blue-green algae of breakout of water bloom, and China Taihu Lake blue-green algae breaks out greatly in recent years, and main algae is microcystic aeruginosa.When wawter bloom is decorporated, microcystic aeruginosa dead or break after can discharge born of the same parents' intracellular toxin-Microcystin (Microsystins is called for short MCs).MCs is seven peptide monocycle hepatotoxin of a class biologically active, is than the chlorophyll stable ring compound that has two keys also, and more than 60 kind of isomer arranged.The blue-green alga bloom of 25%-70% pollutes and can produce the algae toxin in the world, wherein Microcystin (Microcystins, the algae toxin kind that MCs) be that a class frequency of occurrences is the highest, generation is maximum, toxicity is the strongest, works the mischief the most serious.
Molten algae bacterium refers to by direct or indirect mode, suppresses algal grown or cracking frustule, thereby shows the bacterium of algae effect extremely.They extensively are present among seawater, lake, mud and the city appearance water body, be an important component part of biotic population structure and function in the aquatic ecosystem, the control of algal bloom, the balance of keeping the algae bio amount are had important effect.Along with the aggravation of global body eutrophication, breaking out of harmful algae wawter bloom is increased, and the environment that it causes and economic problems paid more and more attention are sought effective wawter bloom and the red-tide control approach is imperative.Utilizing physics, chemistry and other biological method to administer under the very undesirable situation of wawter bloom, molten algae bacterium as the biology of wawter bloom and red-tide control, has caused more and more people's concern.
Summary of the invention
The purpose of this utility model provides a kind of device that utilizes molten algae degradation by bacteria microcystic aeruginosa, can also greatly improve the microcystic aeruginosa clearance by fixing molten algae bacterium, can control flooding velocity, aeration rate and hydraulic detention time, microcystic aeruginosa is fully contacted with bacterium, improve alga-killing rate.
The technical scheme that the utility model is taked is:
A kind of device that utilizes molten algae degradation by bacteria microcystic aeruginosa comprises the water sample case, and the water sample case connects the main reaction post by spinner-type flowmeter, water inlet pipe, and the top of main reaction post sets out water pipe, is provided with aerating apparatus in the main reaction post.
The pottery gravel of three layers of different-grain diameter is housed in the described main reaction post, and from bottom to top particle diameter diminishes.
Described pottery gravel particle diameter is preferably at 1-3cm.
Described aerating apparatus is the aeration head of main reaction post inner bottom part, and aeration head is connected by the outer air pump of tracheae and main reaction post, and tracheae is provided with air flowmeter, valve.
Separation and purification in advance had the molten algae bacterium of the strain WM1(Bacillus megaterium of higher removal effect to microcystic aeruginosa) pour into and the gravel that is fixed in to make pottery is in the main reaction post of filler together with the LB substratum, under the condition of 20 ℃ of room temperatures, oxygen and bacteria culture medium abundance, reaction through two weeks is completely fixed on filler this molten algae bacterium, the aqueous sample stream that contains the verdigris Microcystis aeruginosa is then crossed reactor, can with filler on molten algae bacterial film fully contact, thereby reach purpose with algae removal.
Advantage of the present utility model is:
The pottery gravel is as the medium that depends on of a kind of bacterium, can farthest the molten algae bacterium WM1 that microcystic aeruginosa is had the efficient degradation effect be fixed in the reactor, simultaneously by control hydraulic detention time and aeration rate realize to microcystic aeruginosa fast, safety and removing efficiently.This device can will have the molten algae bacterium WM1(Bacillus megaterium of efficient removal effect to microcystic aeruginosa) effectively be fixed on the filler, and by control hydraulic detention time and aeration rate realize to microcystic aeruginosa fast, safety and removing efficiently.
