Abstract
The invention belongs to the technical field of wastewater treatment, particularly relates to a treatment method of wastewater anaerobic digestive fluid in a pig farm. The invention uses a water hyacinth pond for removing most of the ammonia nitrogen of wastewater anaerobic digestive fluid in a pig farm, later adopts large-scale emergent aquatic plant pond of water bamboo, reeds, and the like, combines artificial float grass and functional microbial inoculum for purifying the yielding water again so as to lead the concentration of ammonia nitrogen in the yielding water to be further reduced, and then adopts an aquatic animal breeding pond with landscape value for purification treatment. The invention not only can achieve standard discharge of the intensive pig farm wastewater anaerobic digestive fluid, but also can create economic benefits by the aquatic economic plants and aquatic animals in the pond and achieve water resource.
Description
Technical field
The invention belongs to the wastewater treating technology field, be specifically related to a kind of improvement method of piggery wastewater anaerobic digestion solution.
Background technology
China was studied the stabilization pond sewage disposal technology since the 1950's.The eighties in 20th century, State Bureau of Environmental Protection has been presided over the traditional stabilization pond technical study that is listed in country's " the Seventh Five-Year Plan " and " eight or five " key scientific and technological projects, at aspects such as the biological reinforced processing mechanism of traditional stabilization pond, facility operation rule, design and operation parameters, many valuable achievements in research have been obtained.Many traditional stabilization ponds are now had in China, have played crucial effect on the outskirts of a town with in the water pollution control in rural area.But there is following main drawback in traditional stabilization pond: floor space is big; Bottom, pool waterproof measure is poor, and sewage is seeped in the underground water easily; Lack suitable pre-treatment or pre-processing device; Because the design of waterpower fluidised form is bad, short stream in the pool, volumetric efficiency is low.Compare with external advanced person's pool treatment system, China's tradition stabilization pond all is more coarse and backward on design, construction, operation, aesthetics and ecology.Shortcomings such as tradition stabilization pond floor space is big, processing efficiency is low have limited applying of its technology.
The ecology pond systems has been introduced the notion of intensified ecological, mainly from saving occupation of land and raising the efficiency and innovate, by in the system of the pool, setting up stable food link network artificially, make the pool itself be the sewage disposal unit be again to utilize the unit, in sewage disposal, can realize sewage recycling.Economical, energy-conservation, natural purification system-Biostatic pool is subjected to extensive concern with its plurality of advantages (less energy-consumption, high purification rate, effluent quality be better than aspect a lot of activated sludge process water outlet, operation simple and easy etc.) efficiently.Engineering practice both domestic and external in recent years and studies have shown that, nutritive substances such as the waterplant in such pool not only has higher growth rate, can decompose and absorb nitrogen in the water fast, phosphorus, and plant easily shifts out water body, both can be used as the nutrient fodder of ox, pig, duck, can macerate system green manure again, the hydrocoles edible can be created considerable economic.
Summary of the invention
The present invention is directed to big, the shortcomings such as processing efficiency is low, the too much algae of generation of floor space that traditional stabilization pond treatment process exists, propose a kind of comprehensive ecological pool system handles method of piggery wastewater anaerobic digestion solution.
The present invention on the basis of traditional stabilization pond technology, the principle of the ecological and intensified ecological of utilization, the biotope that will differ from one another has sewage purification and goes out the novel stabilising pool technology of recycling of water resource dual-use function with mode combines in accordance with the appropriate ratio.The Biostatic pool combines with the waterplant pool and the aquaculture pool, and takes into account the landscape function of ecological pond.
The present invention relates to a kind of combined biological oxidation pond at the piggery wastewater anaerobic digestion solution purifies and the resource utilization new technology.Its technology characteristics is: the most ammonia-nitrogen of removing the piggery wastewater anaerobic digestion solution with the Herba Eichhorniae pool, adopt the large-scale emergent pools such as wild rice stem, reed that water outlet is further purified then, ammonia nitrogen concentration in the water outlet is further reduced, meet hydrocoles growth requirement, further adopt the hydrocoles that has landscape value concurrently to culture the pool and carry out purifying treatment.Not only can realize the qualified discharge of piggery wastewater that intensifies, and can create economic benefit, realize waste water reclaiming by aquatic economic plants in the pool and hydrocoles.
