Description

A kind of for black and odorous water processing means and catalyst particle preparation method thereof
Technical field
The present invention relates to a kind of technical field of sewage, especially relate to a kind of processing means for black and odorous water.
Background technology
In mid-term in 20th century, the Times river of Britain is one of river that black smelly problem occurs the most the earliest.Last century 70 In the age, the Rhine of Germany is owing to flowing through heavy industrial district, and trade effluent enters the Rhine, and its pollution has also reached peak.Simultaneously Phase the U.S. river, Chicago, river, Delaware etc., also because suffering that severe contamination causes water body long-term black smelly.In Chinese Urbanization and During process of industrialization is accelerated, owing to water pollution control is delayed with control measures, or limited in one's ability and low SI, one A little urban water-body especially small and medium-sized cities water bodys, are directly becoming primary discharge passage and the place of industry, agricultural and sanitary wastewater, Cause urban water-body large area contaminated, cause body eutrophication, form black and odorous water.So-called " black smelly ", principally falls into ring Border view, physical index category.Refer to that visually river water presents the obvious abnormal color produced because of pollution (typically Black or blacking up color), produce simultaneously and cause people to do not feel like oneself the abnormal smells from the patient even detested in olfactory sensation, be the aesthetic pollution of water body Modal a kind of phenomenon.The black smelly phenomenon in China river occurs in Suzhou River the earliest, subsequently the Qinhuaihe River in Nanjing, Suzhou , all there is black smelly phenomenon in various degree in outer fosse, the Huang Xiaohe in Wuhan and the inland river etc. in Ningbo.In recent decades, black smelly water Scope and the degree of body are constantly aggravated, and in major part section, city, the whole nation, the water body overwhelming majority flowing through busy areas is subject to Pollution in various degree.Two grades of the most each large watershed are more prominent with the black smelly problem in three grades of tributaries, and degradation by Year improves.Such as Huaihe River, within 2014, National Environmental quality condition publication data show, master stream water quality whole year all more than IV class water, But the bad V class water body of fork is more than 23%;In each big water system, the bad V class water quality level in Haihe River is the highest, state's control section prison Survey data show, bad V class in master stream reaches 37%, bad V class in tributary reaches 44%.
Black and odorous water mainly water hypoxia causes, also the most relevant with body eutrophication and bed mud deposition.Country Great water special project correlational study result shows, when dissolved oxygen is reduced to 2.0 mg/L, water body will be in anaerobic condition.Work as dissolving When oxygen is 3mg/L ~ 5mg/L, Organic Pollutants In Water and ammonia-nitrogen content the most also can exceed surface water V class standard, present Color has taste state, but with the presence of aquatile;When dissolved oxygen is more than 6 mg/L, water body is in aerobic state, organic matter degradation Dramatically increasing with ammonia oxidation speed rate, water body starts have self-purification capacity.
The black-odor control of city river follows " external source reduction of discharging, endogenous desilting, purification of water quality, clear water supply, ecological recovery " Technology path.Wherein external source reduces discharging and endogenous desilting is basis and premise, and purification of water quality is interim means, and hydrodynamic force is improved Technology and ecological recovery are long-acting safeguards.
One is external source interrupter technique: external source block include city cut dirt receive pipe dough-making powder source control two kinds of situations.For shortage Improve the water body of sewage collection system, by the sewage conduct built and transformation water body is littoral, sewage is dammed and includes sewage receipts in Collection and processing system, cut down the directly discharge of pollutant from source.Carry out cutting dirt for the condition that there is no at present and receive the sewage of pipe, Efficient primary reinforcement sewage disposal technology or technique can be used in position, rapidly and efficiently remove the pollutant in water, it is to avoid sewage The in line pollution to water body.City surface source pollution is mainly derived from the pollutant contained in rainfall runoff, and it is main that it controls technology Technology and ecological revetment technology etc. is controlled including the low impact in various cities exploitation (such as sponge city) technology, early-stage rainwater.City The rubbish etc. of water body periphery is the important sources of area source pollutants, and therefore the cleaning of water body periphery rubbish is that pollution of area source controls Important measures.
Two is endogenous control technology: technology of desilting and dredging generally has two kinds: one is to drain desilting after lake/river;Another Plant is directly to remove mud from water with dredger.The range of application of the latter is relatively wide, and river,lake and reservior all can use it.Desilt and dredge energy Relatively quickly improve water quality, but desilting process enters water body in a large number because disturbance is easily caused pollutant, has influence on water ecology system Stablizing of system, thus there is certain ecological risks, it is impossible to as the Long term control measure of a kind of polluted-water.
Three is water purification technology: the water purification technology of city black and odorous water specifically includes that artificial aeration's oxygenation (is passed through Air, pure oxygen or ozone etc.), Dissolved Oxygen in Water concentration and oxidation-reduction potential can be improved, alleviate black and odorous water situation.Germany Thayer river, Britain Times river, Australia's Swan River, the Suzhou River etc. of China all have employed the side of aeration oxygen replenishing in administering Method.Flocculation sediment technology is directed in the water body of urban polluted river add the medicaments such as iron salt, calcium salt, aluminium salt, is allowed to and water body Middle dissolved phosphorus hydrochlorate forms insoluble solid and is precipitated in riverbed bed mud.But it should be noted that the expense of chemical flocculation Higher, and produce more deposit, some chemical agent has certain toxicity, can form secondary when environmental condition changes dirty Dye.Artificial Wetland Techniques is the technology utilizing soil microorganism plant ecosystem to be removed nutritive salt, uses more Free water surface wetland or current wetland, wetland plant may select submerged plant or emergent aquactic plant.Ecological floating island is a kind of through artificial Design-build, float on for animals and plants and growth of microorganism, the biological and ecological facility multiplied, perch on the water surface, by building water Pollutant in water body are ingested, are digested by territory ecosystem, degraded etc., it is achieved purification of water quality.Stabilization pond is a kind of artificial-strengthening The water purification technology that measure combines with self-purification function, such as many pools technology and Aquatic-plant Pond technology etc..Available Polluted-water is purified by the littoral multiple natural pools of water body or artificial pool.
Four is hydrodynamic force improving environment: water transfer not only can be by pollutant dense in a large amount of clean water source diluting black and odorous waters Degree, and the diffusion of pollutant can be strengthened, purify and export, for receiving the city that dirty load is high, hydrodynamic force is not enough, environmental carrying capacity is low City's black and odorous water regulation effect is obvious.But calling clean water to improve quality of river water is the waste to water resource, should use as far as possible Unconventional water source, such as recycled water and making use of rain and flood.To prevent from introducing new polluter during water transfer simultaneously.
Five is Ecological recovery technology: black and odorous water phenomenon causes algae to break out often caused by concentration of nitrogen and phosphorus in water is higher Secondary problem, causes water quality deterioration, Algae toxins problem and other hydrobiological mortalities, then causes black smelly recurrence.City River course, city eutrophication control it is crucial that the control of phosphorus, in current sewage disposal plant effluent standard, the index limits of phosphorus is far above Surface water standard limited value.Therefore, limit phosphorus in local implementation region with good conditionsi or raising sewage total phosphorus discharge standard is extremely to have The measure of effect.The phosphorus entering water body is deposited in bed mud with phos-phate forms mostly, therefore keeps cement interface alkalescence, has Oxygen condition is the main behave that river course eutrophication controls.Algal grown Artificial Control technology includes various physics, chemistry and life Thing technology.Physical control technology includes that algae is directly collected and kills algae etc. with ultraviolet, chemical control technology include adding inorganic or Organic pressing down (killing) algae agent, BIOLOGICAL CONTROL technology includes planting algal control water plant or throwing in food algae Fish etc..These measures are general Use when emergent.Water Ecological Recovery includes water plant and the reparation of aquatic animal (such as Fish, zoobenthos etc.) food chain Build with Hydrology Ecosystem System.Utilize the food chain that ecological principle builds, can persistently remove in urban water-body pollutant and Nutrient, improves water body habitat.
