One, stabilization pond
Stabilization pond is artificially set up impermeable layer and embankment, the use of microbial metabolic activity in the water body, so that the pollutants undergo a series of physical and chemical reactions, microorganisms, such as fungi, bacteria, algae and protozoa, so that pollutants can be effectively removed and degraded. This treatment technology highlights the advantages of no sludge treatment, less investment, low operating costs; its disadvantages are affected by the climate, occupies a large area of land, low load, the treatment effect is not stable enough.
Two, biofilm domestic sewage treatment
Integrated fluidized bed biofilm domestic sewage treatment equipment in the treatment effect, the degree of automation, the ability to resist the impact load than the traditional AAO process has more advantages; and MBR integrated equipment has mutual advantages, but the cost is relatively lower, is a kind of future market needs, has certain advantages, the applicability of the process of strong! It is a kind of process that meets the needs of the future market and has certain advantages of use and strong applicability. Widely used in rural areas, towns, settlements, neighborhoods, hotels, restaurants, resorts, schools, office buildings and other daily sewage treatment, reuse. It is also suitable for the management of black smelly water bodies and the upgrading of various types of domestic water treatment facilities. Highly efficient removal of COD, SS, ammonia nitrogen, total nitrogen, BOD, total phosphorus and other pollutants. At present, the equipment has been carried out in Loudi Shuangfeng engineering applications, and a series of patents have been approved.
Three, modular anaerobic + artificial wetland
Clear source features "anaerobic - artificial wetland" ecological combination of systems to deal with rural sewage, rainwater, through the process of water sampling and analysis of each process, and evaluation of its treatment effect. Comprehensive results show that: artificial wetland effluent quality and sewage collection tank sewage indicators, the average COD removal rate of 63.2%, NH + 4-N [o] for 46.65%, TN for 53.0%, TP for 44%. It shows that the combination of the system has a good removal efficiency of the pollution indicators, and low investment in engineering, easy to manage, ecological and landscape benefits, suitable for popularization and application in rural homes.
