Summary of the invention
Technical problem to be solved by this invention is to provide a kind of matrix of strengthening formaldehyde in air plant purification speed with low cost and preparation method simple to operate.
The technical solution used in the present invention is as follows:
(1) gather garden soil 500g, pick up out deadwood and rotten leaf, and load in brown bottle;
(2) add the formaldehyde solution of 50mg/L when starting, do not have soil, after sealing two days, strain liquid, add the formaldehyde solution of 100mg/L again, by that analogy to the formaldehyde solution of 250mg/L, collect the solution strained for the last time, the bacterium liquid after filtration loads in clean brown bottle;
(3) cultivate bacterium liquid with the formaldehyde solution of 4 kinds of concentration (50mg/L, 100mg/L, 200mg/L, 250mg/L), result shows that the bacterium liquid degradation rate cultivated with the formaldehyde of 50mg/L is the fastest;
(4) get bacterium liquid 400mL, the concentration adding active sludge and soil ulmin is respectively 4g/L, 2g/L, nutritive medium 100mL, and with every day, the formaldehyde solution of 50mg/L cultivates three days, obtained matrix;
(5) with closing transparent glass cylinder, glass jar top freely can be opened and is provided with the test sample hole of diameter 1cm.Concentration known is added and volume can the formaldehyde solution of cover glass cylinder bottom completely in said apparatus, simulate Formaldehyde Pollution of Indoor Air environment, matrix is quantitatively joined in the vial of outsourcing aluminium-foil paper, and plant is moved into rapidly, and seal bottleneck and collar space with sponge and aluminium-foil paper, then vertically put into simulator, tightly seal with wide adhesive tape, do one group simultaneously and do not add contrasting of matrix, the concentration of formaldehyde solution in glass jar is measured after certain treatment time, calculate degradation rate, show that the efficiency that the ratio adding matrix does not add the plant degradation formaldehyde of matrix exceeds 20% ~ 80%,
The condition of cultivating in described step (2), (3), (4) and (5) is temperature 25 ~ 30 DEG C, and pH is 5 ~ 6;
The present invention compared with prior art has the following advantages:
1, the starting material used in the present invention are easy to get inexpensive, and prepared matrix can to purify air the efficiency of middle formaldehyde by fortification of plants, and the formaldehyde efficiency of the 50mg/L that degraded in 4 hours that matrix can be independent is 80% ~ 95%.By the checking in simulator, add matrix and strengthen 20% ~ 80% with the efficiency of the plant degradation formaldehyde not adding matrix, efficiently solve the shortcomings such as degradation efficiency in conventional art is low, consuming time;
2, the present invention adopts methyl ethyl diketone determination of color concentration of formaldehyde, efficiently solves the complicated operation of technology, the shortcomings such as required expensive equipment;
3, the matrix made of the present invention is conveniently preserved, cost is low, preparation method is simple.
