Abstract
A water distribution device of a horizontal subsurface wetland sewage treatment system is characterized in that quick lime packing is filled in a water quality regulating groove, bottoms of the water quality regulating groove and an overflow groove are communicated via a bottom outlet pipe, and a water outlet of a water distributing pipe on the upper portion of the overflow groove is disposed above a wetland water distribution region. By aid of the water distribution device of a horizontal subsurface wetland sewage treatment system, water quality factors such as pH value of sewage entering wetland meet requirements of the wetland treatment system, uniform water distribution is realized, simultaneously packing in the water distribution region is not easy to be blocked, and sewage treatment effect is obvious.
Description
Technical field
The utility model relate to a kind of horizontal drowned flow marsh sewage treatment system water dispensing apparatus, especially be applied to water suspended sediment concentration into higher, through the sewage wet land treating system of acidication.
Background technology
In order to realize effective processing, adopt the technology of artificial swamp to obtain admitting comparatively widely to sewage.Artificial swamp is made up of filler, plant and microorganism etc., is a kind of effect ecosystem preferably of disposing of sewage.According to the difference of system's water distribution manner or the difference of water flow pattern in system, artificial swamp can be divided into three types of surface current wetland, horizontal drowned flow wetland and vertical-flow wetlands.
The horizontal drowned flow wetland is made up of filler, plant and microorganism, and there is water-resisting layer at the bed end, and the gradient is vertically arranged.Drop in the bed in the cloth ditch that sewage is constructed from feed-water end along bedside, is horizontal diafiltration along filler bottom undercurrent and advances, and flows out from the other end exhalent canal.Main physics, chemistry, the biological synergy of relying on finished the scavenging process of waste water, strengthened the soil removability of the natural wetland ecosystem.Horizontal drowned flow wet land system hydraulic load and pollution load are bigger, and be good to treatment effects such as chemical oxygen demand (COD) (COD), biochemical oxygen demand (BOD) (BOD), suspended solids (SS) and heavy metals, and oxygen derives from the root system of plant transmission, can avoid stench and mosquitos and flies phenomenon.This technology is compared with traditional secondary biochemical Sewage treatment systems, has characteristics such as investment is low, energy consumption is low, ecological benefits are high and processing cost is low, effluent quality is good.
Present horizontal drowned flow wet land system is used existing problems: because hydrolysis and acidification result that sewage enters before the wetland are undesirable, make easily that into water pH value is on the low side, can cause the decline of wetland processing production capacity; And the ununiformity of water distribution can cause that the filler of inhalant region stops up.
Summary of the invention
The technical problems to be solved in the utility model provide a kind of water quality factors that guarantees to enter the sewage of wetland satisfy water distribution that wet land treating system required, can guarantee simultaneously wetland evenly, the not susceptible to plugging horizontal drowned flow marsh sewage treatment system of cloth pool filler water dispensing apparatus.
The utility model solves the problems of the technologies described above with following technical scheme:
Horizontal drowned flow marsh sewage treatment system water dispensing apparatus of the present utility model, in the water quality regulation groove, be filled with limestone filler, the water quality regulation groove has the bottom rising pipe to be communicated with the bottom of overflow groove, and the water outlet of the water distributor on overflow groove top is positioned at the top of wetland water distributing area.
Horizontal drowned flow marsh sewage treatment system water dispensing apparatus of the present utility model, make the water quality factors such as sewage pH value that enter wetland satisfy the wet land treating system requirement, and the water distribution of having realized wetland simultaneously is even, cloth pool filler is difficult for stopping up, and wastewater treatment efficiency is obvious.
Description of drawings
Fig. 1 is the structural representation of the utility model horizontal drowned flow marsh sewage treatment system water dispensing apparatus.
Embodiment
The problem that exists when using at present horizontal drowned flow wet land system, the utility model provides a kind of horizontal drowned flow marsh sewage treatment system water dispensing apparatus, and this device comprises water quality regulation groove, overflow type water distribution system and wetland water distributing area.Purpose is the requirement that the water quality factors such as sewage pH that guarantee to enter wetland satisfy wet land treating system, with better performance wetland processing power, guarantees that simultaneously water distribution is even, and cloth pool filler is difficult for stopping up.
Horizontal drowned flow marsh sewage treatment system water dispensing apparatus of the present utility model, essence are to carry out the pre-treatment of water before sewage enters wetland earlier.In pretreated device, pile with fist shape limestone filler 3 in the water quality regulation groove 1; Water quality regulation groove 1 has bottom rising pipe 4 to be communicated with the bottom of overflow groove 5, and the water outlet of the water distributor 6 on overflow groove top is positioned at the top of wetland water distributing area 7.Wetland water distributing area 7 is to be positioned at one section about 300mm of thickness of wetland forward, height, wide and wetland height, zone that wide difference is identical, fills big particle diameter gravel in this zone.Porous plate 8 is interior wetland water distributing area 7 of wetland and the dividing plate between other small particle size filler.
After sewage disposal brings into operation, enter water quality regulation groove 2 from the sewage of sewage collection system by main 1, fist shape limestone filler 3 has been tackled thicker floating matter and suspended substance in the groove, and is smooth and easy to guarantee follow-up water distribution, prevents that the inhalant region filler from stopping up; Limestone filler 3 can play neutralizing effect to sewage simultaneously, strengthens the removal ability to organism and phosphorus.Sewage in the water quality regulation groove enters overflow groove 5 through bottom rising pipe 4, realizes the adjusting of water quality, the water yield.Overflow water in the overflow groove falls into wetland water distributing area 7 by each water outlet of water distributor 6, is carrying out water distribution uniformity simultaneously, contacts with air and obtains reoxygenation, for follow-up wet land treating system provides required dissolved oxygen amount.Sewage after finishing the water quality and the water yield and regulating, the water distributing area 7 through filling big particle diameter gravel evenly oozes down, and simultaneously, the small particle size filler of only being separated by with porous plate 8 with water distributing area 7 is under wicking action, and realization sewage horizontal drowned flow in wetland plays the transverse flow guide effect.
