8) water retention in pond two stops and circulating, standing;
9) water in pond two is pumped to pond one: cycle filter pump pumps the water of Chi Erzhong to pond one, due to water level in pond two Decline and form negative pressure, pond two breather air inlet exposes oxygen, pond two particulate matter agglomerate of biomembrane absorption under suction function comes off, pond One water inlet exposes the air that oxygen is discharged in pond, and described water inlet refers to that the water in pond two is pumped to pond one, and pond one is simultaneously using water inlet recoil Service sink one, meanwhile, the air in pond one is discharged by the breather in pond one;Chi Ershui under gravity, from wetland surface Internally flow, the pollutant agglomerate in cleaning hypothalluses 1 and hypothalluses 2, so as to depart from substrate, drops to hypothalluses 3 He Hypothalluses 4;
10) repeat step 2) -9), water circular treatment between pond one and pond two, until after water process is up to standard, give off Go.
The anaerobism of this utility model biological and ecological water treatment facilities aerobic circulation processing pool have the following characteristics that
1) structure: adopt rectangle or square, the ratio of length and width is between 1:2-1:1 more cell body the bottom surface;Pond number Or total number of divisions is typically no less than 2 multiples.
2) host material
Host material selects: the selection of each layer substrate and filling thickness in artificial swamp, the selection of substrate answer treatment in accordance with local conditions, Gather materials on the spot, to reduce the cost of artificial swamp, stromal thickness should determine according to concrete water quality and field condition, total substrate bed Thickness generally 1m about.For the substrate lacking nutrient supply or the excessive substrate being unfavorable for plant fixed growth of hole, The thick soil of 15 ~ 25cm need to be covered above substrate, as the substrate of plant growing.
Filler: in ecological pool, the filtration of particulate matter is mainly completed by filler, soluble pollutants then pass through biomembrane and water Plant root system removes.
Bio-filter stuffing is from being suitable to invade for a long time the elastic filler of Sewage Environment, soft-filler, light porous filler Or ceramic grain filter etc., typically select ceramic grain filter or light porous filler, ceramic grain filter particle diameter is preferably 0.5-30mm, light porous Packing material size preferably controls in below 45mm, and the water distribution of biofilter must be uniformly.
Biofilter structures are simple, during day-to-day operation, mainly patrol and examine the power-equipments such as water pump and whether filtrate occurs Clogging, whether ventilation effect is good;It should be noted that antifreeze when water temperature in winter is relatively low, reduce amount of inlet water load simultaneously, with Ensure treatment effect;
3) vegetation selects wetland water plant mainly to include emergent aquactic plant, submerged plant and floating plant.Different areas Domain, different growing environment, the wetland plant species of suitable growth is different.Should choose that process performance is good, survival rate is high, Stain resistance is strong and has necessarily aesthstic and economic worth water plant.As water plant be Herba Typhae, phragmites communiss, Medulla Junci, water Radix Ophiopogonis etc..
4) hydraulic condition emphasis considers to cause the various influence factors of Wetland clogging, and Wetland clogging mostly occurs in system bed Body portion, the material that results in blockage is most of to be inorganic matters, and this shows that particulate matter in the sewage precipitation in wetland bed is to make Become the main cause of Wetland clogging.Additionally, root system of plant and its attachment etc. are also a big inducement of Wetland clogging.
5) biological layer is processed is to process skill by filling filler in pond and a kind of of enhanced water anaerobic treatment effect Art, in sewage, larger molecular organicses anaerobism in pond is broken down into small organic molecule, can effectively reduce subsequent processing units Organic pollution load.
Biological layer processes advantage: reduced investment, simple, easy maintenance of constructing;Earthing planting plants above it, with plant Form artificial swamp.
6) ecological pool Aerobic Process for Treatment, according to waste water processes, can be divided into catalytic oxidation, a sub-contact to aoxidize and many Secondary catalytic oxidation.Biological tank middle setting intermediate sedimentation pond, for filtering pump circulation water inlet, filtering biological matter, improves cell body saturating Aqueouss and effluent quality.
Advantage during ecological pool Aerobic Process for Treatment: microbial biomass stably enriches, the strong adaptability to water quality, water yield fluctuation;Operation Easy;Good to pollutant removal.
The pretreatment facility such as sedimentation tank and filter pump is set in biological tank anaerobism, aerobic circulation processing pool, to prevent from blocking. Need the aerating system of reasonable Arrangement biological contact oxidation pond in pond, realize uniform aeration.Filler filling will rationally prevent from blocking up Plug.
