Embodiment Construction
[0018] A method for cultivating oil algae using urban domestic sewage. First, the urine discharged by people is separated from the domestic sewage at the source, and the separated urine solution is stored by storage facilities; secondly, the stored urine solution is transported to Placed in the above-mentioned oil algae culture facilities 1 in the residential quarters and office buildings, etc., the nutrient salts in the urine solution are used to cultivate the algae and at the same time realize the purification of the urine; finally, the cultured mixed solution is transported to the algae water The separation station conducts separation treatment, in which the separated algae are recovered as resources, and the separated residual liquid is discharged into the municipal pipe network and enters the sewage treatment plant for harmless treatment before being discharged up to standard.
[0019] In the embodiment of the present invention, the urine solution in the first step is dilu...

The invention relates to a method for culturing oil algae, and especially relates to a method for culturing oil algae by using urban domestic sewage. The invention adopts the following technical scheme: firstly, separating urine of people from domestic sewage at source, and storing the separated urine solution by using a storage facility; secondly, conveying the stored urine solution to an oil algae culturing facility placed in a residential area, an office building and the like, and realizing the culturing of the algae by using nutritive salts in the urine solution while purifying the urine; and finally, conveying the obtained mixed liquor subjected to culturing to an algae-water separation station to carry out separation treatment, carrying out resource recycling on separated oil algae, and draining separated residual fluid into a municipal pipe network and then feeding the fluid into a sewage treatment plant to carry out innocent treatment, and draining the fluid after the fluid meets the discharge standards. Through adopting the scheme, the method disclosed by the invention solves the existing problems, and a method for culturing oil algae by using urban domestic sewage is provided.
Description
technical field [0001] The invention relates to a method for cultivating oil algae, in particular to a method for cultivating oil algae by using urban domestic sewage. technical background [0002] With the improvement of sewage treatment plant discharge standards and the increase in population, the problem of upgrading urban sewage treatment plants with the main goal of reducing the discharge of nutrients such as nitrogen and phosphorus has become increasingly prominent, and there is currently no effective solution. solution. [0003] About 80% of the nitrogen and 50% of the phosphorus in domestic sewage come from urine, and the volume of urine only accounts for about 1% of the volume of domestic sewage. Therefore, using source separation toilets to separate urine from domestic sewage has become a human treatment An innovative method for sewage, but there is still no effective means for the treatment of high-concentration source separation of urine. [0004] On the other ...
