Description

Deep purification of waste water technology
Technical field:
The present invention relates to a kind of deep purification of waste water technology.
Background technology:
Sewage is after second-stage treatment at present, again through advanced treatment, advanced treatment generally comprises filtration, charcoal absorption, chemical dephosphorization, nitration denitrification denitrogenation, micro-filtration, ultrafiltration, surpasses in reverse filter, reverse osmosis, stabilization pond, soil processing etc., facts have proved, these existing secondary effluent treatment processs, its effect is all not good.
Summary of the invention:
The purpose of this invention is to provide a kind of deep purification of waste water technology, this technology can effectively be handled secondary effluent, beautifies the environment, forms ecoscape again, can also make full use of existing water resources, obtains considerable economic.
The object of the present invention is achieved like this:
(1) ecological pond
The ecological pond of the existing type of stream is the initial energy with sun power, by in the pool, planting aquatic crops, carrying out aquatic products and aquatic bird cultures, form artificial ecosystem, under the promotion of sun power (solar radiation provides energy), material migration by many food chains in the ecological pond, the transmission step by step of conversion and energy, transform, it is bacterium and fungi that decomposer's biology is wherein not only arranged, producer's biology is algae and other waterplant, also has human consumer's biology, as fish, shrimp, shellfish, spiral shell, goose, duck, wild aquatic bird etc., the three shares out the work and helps one another, pollutants in sewage is carried out more effective processing and utilization, and bacterium and fungi are in anaerobism, be carbonic acid gas with organic matter degradation in the aerobic and facultative environment, ammonia nitrogen and squama hydrochlorate etc.; Algae and other waterplant absorb these mineral products by photosynthesis and breed its body as nutrition, emit oxygen simultaneously, continue the oxidative degradation organism for aerobic bacteria; Microalgae that increases and bacterium, fungi make its breeding as the bait of zooplankton (as wheel animalcule and water flea etc.), and they make the fish breeding as the bait of fish again; Small fish makes the duck growth as the concentrated feed of duck again, also is beneficial to the growth and the breeding of large-scale economic fish, and small-sized algae also can be by predations such as spiral shell, freshwater mussel, shrimps; Macro and other waterplant are consumed by herbivorous fishes and duck, goose etc.Can form many food chains thus, and constitute the crisscross food web ecosystem.If between each trophic level, keep suitable quantity ratio and energy ratio, just can set up good ecological balanced system.Sewage enters in this ecological pond, organic pollutant is wherein not only purified by bacterium and fungus degrading, and the final product of its degraded, some mineral compound are as carbon source, nitrogenous source and phosphorus source, with sun power is the initial energy, participates in the metabolic processes in the food web, and moves conversion from low battalion level step by step to high battalion level, be transformed into products such as aquatic crops, fish, shrimp, freshwater mussel, goose, duck at last, thereby obtain considerable economic.The present invention is provided with the culvert pipe in ecological pond end bottom and links to each other with the view pond, and water outlet is the waterfall state and enters the view pond from overground part and culvert pipe respectively.
(2) view pond
Modern sewage work general requirement is built up garden type unit, need certain greening and make scape, most of sewage work separates setting with fountain with sewage treatment process, fountain needs often to change water on the one hand, otherwise be prone to peculiar smell, electric energy is wasted in the fountain Open daily on the other hand, with the part of landscape pond as sewage treatment process, fountain is set in the pond, culture a large amount of ornamental fish and other fish, landscape pond is streamlined, throughout the year the long stream of water, Running water never becomes putrid, front end at landscape pond is provided with drop waterfall, and central authorities are provided with fountain in the pond, this in two method can both carry out oxygenation to water, be equivalent to surface aeration, growth to fish is highly beneficial, can also increase dynamic aesthetic feeling, and the end in the pond is provided with culvert pipe and beautiful foot bridge, water outlet is the waterfall state and enters sandfiltration channel, forms the artistic conception of small bridge over the flowing stream.Fish in the landscape pond also play a part necessarily to the further purification of water on the other hand, and heavy metal, algae, bacterium, intestinal bacteria in the water are further reduced.
(3) sandfiltration channel
The water outlet of landscape pond does not reach the reuse water standard, and sandfiltration channel of the present invention is streamlined, by seven layers of sandfiltration channel systems slowly filter purify waste water, utilize seven layers of slow filtering technology make filtering velocity be controlled at 1-1.5 rice/hour.The filtrate headwater depth is 20 centimeters, and this technology has been exempted the back flushing operation, has not only saved processing cost, and has significantly reduced the waste of water resources.The suspended matter in the landscape pond can also further be removed by its sandfiltration channel system, and some microorganisms of growth also can be removed a part of soluble material on filtrate, make water outlet more as clear as crystal.A water part is penetrated in the header, flows in the clean water basin by gravity, and in order to the reuse of water, another part flows to landscape lake or view korneforos along with the top layer of sandfiltration channel is the waterfall state.
Technology of the present invention can effectively be removed TSS and other impurity in the secondary effluent, and it is low to have a cost, can make full use of landform, running maintenance is convenient, beautify the environment, form ecoscape, management is simple, and sludge yield is few simultaneously, can bear the sewage water yield and the water yield and fluctuate on a large scale, and advantage such as adaptive faculty and anti-shock loading power is strong, fundamentally having eliminated environmental pollution, is a kind of effective deep purification of waste water technology, and this slow filtering technology not only can be removed TSS and unnecessary algae and mushroom effectively, also make water outlet seem more attractive in appearance, and reached the standard of reuse water fully.
