Abstract
The utility model relates to an equipment of sewage treatment, consisting of a bed body and a water distributor. A covering layer, a water-distribution layer, a sewage treatment layer and a cushion layer are arranged inside the bed body. The bottom of the sewage treatment equipment is provided with a water outlet. A water-distribution system composed of a water-inducing tube and a branch tube is distributed in the water-distribution layer. The sewage treated by each layer inside the bed body has the advantages of achievement of high clearance, better water quality of yielding water than that of conventional secondary biological treatment plants, and low investment. Flowers and grasses can be planted in the covering layer, and thereby not only increasing clearance nitrogen and phosphate in the sewage, but also beautifying environment.
Description
The utility model relates to sewage disposal device, relates in particular to the equipment of sanitary sewage disposal.
Existing residential quarters sanitary sewage disposal technology mainly contains buried secondary biochemical treatment equipment and two kinds of treatment processs of artificial swamp.
Buried secondary biochemical treatment equipment is that adopt glass reinforced plastic or concrete structure body a plurality of unitary is embedded in subterranean rectangle form pool, the blast aeration machine then is installed in the workplace of ground, provide aeration by underground gas distribution pipe for biological contact oxidation pond, sewage passes through after the cell processing such as settling pit, anaerobic pond, biological contact oxidation pond and settling tank successively from subsurface disposal.The weak point of this technology has: 1. sewage disposal device is embedded in undergroundly, and the cleaning of repair and maintenance and mud is difficulty; 2. the noise of blast aeration machine room has pollution to surrounding environment; 3. water-fast matter and water yield impact load ability are relatively poor, and effluent quality is also relatively poor, and most treatment facility water outlets can not reach the emission standard of secondary biochemical treatment factory; 4. initial cost, processing energy consumption and processing cost are higher; 5. the excess sludge that is produced has secondary pollution to surrounding environment.
Artificial swamp is a kind of low investment, less energy-consumption and sewage disposal new technology cheaply, and two kinds of forms such as surface flow and underground undercurrent are arranged, and mainly adopts underground drowned flow artificial wet land in the residential quarters sanitary sewage disposal.Underground drowned flow artificial wet land adopts gravel as sewage disposal matrix, and in matrix, plant and be implanted with the aquatic macrophyte of secreting the oxygen ability such as reed etc., utilize the oxygen ability of secreting of waterplant to provide oxygen for the organic substance that the microbial film on the artificial swamp matrix decomposes in the sewage.The weak point of this technology has: 1. processing power is less, floor space is bigger; 2. be easy to generate and stop up and the surface low problem, so that environmental health problems such as frowziness and mosquitos and flies; 3. gravel matrix is less to the loading capacity of phosphorus, and work-ing life is not long; 4. can only planting aquatic plants, can not plant the Lu Sheng flowers.
The purpose of this utility model is: adopt underground perforated pipe water distribution and the top layer is topped and batching is handled mode, make sewage batch and treating processes in be not exposed in the air, reach the purpose of environmental health problems such as the stink that alleviates sewage and mosquitos and flies; And with bed surface overcoat as the matrix of soilless cultivating flowers with utilize sanitary sewage to carry out the soilless culture production of flowers as nutritive medium, reach and both increase the attractive in appearance of treatment tank, production fresh-cut flowers utilize purposes such as flower plant purifying domestic sewage simultaneously again.
The utility model is made up of bed body, water distributor.In the bed body overcoat, water distribution layer, sewage disposal layer and bed course are set, bed body bottom is provided with water port, and water distributor is located in the water distribution layer, and water distributor is made up of aqueduct and many arms, and arm is fixed on the aqueduct, has aperture on the arm.
Now be described further in conjunction with the accompanying drawings:
Fig. 1 is the utility model structure iron.
1---bed body 2---aqueduct 3---arm 4---overcoat
5---water distribution layer 6---sewage disposal layer 7---bed course 8---water port
Make with non-leakage material the bed wall and the bottom of the utility model bed body 1, and its wall is the brick structure of finishing cement if build on the ground, and the bottom is a concrete structure.The bed body from bottom to top distributes: bed course 7, sewage disposal layer 6, water distribution layer 5 and overcoat 4.Cushion thickness is 10-20cm, and gravel, little gravel and peastone from bottom to up distribute; More than the sewage disposal layer thickness 80cm; Placing with blast furnace slag or coal ash slag or sand in the sewage disposal layer is major ingredient, is equipped with the mixed fillers that the farmland tillaging layer soil and the peat composed of rotten mosses or peat are mixed and form, and the volume ratio of its major ingredient and batching is 8-18: 1: 1; Water distribution layer thickness 5-10cm places gravel and peastone in the layer; The thickness of overcoat is 5-15cm, available farmland tillaging layer soil or topped with the mixed fillers of said ratio.Water distributor is distributed in the water distribution layer, wherein end sealing, and the other end is connected with sewage water inlet pipe, wherein aqueduct is positioned at the midline position of a body, and its length is suitable with bed body width, and arm is fixed in the aqueduct both sides, half of length of tube bed body length, the downward position of arm has aperture.
The utlity model has following advantage:
1. the clearance height, effluent quality is excellent, hydraulic loading rate is high.To COD, BOD in the sanitary sewage of residential quarters
5, NH
4 +The clearance of-N and TP reaches 80-90%, 85-95%, 60-80% and 60-80% respectively; COD, BOD in the treat effluent
5, SS, NH
4 +The mean concns of-N and TP is better than conventional secondary biochemical treatment plant effluent water quality respectively less than 60mg/L, 20mg/L, 20mg/L, 15 mg/L and 0.5mg/L; Its year, hydraulic loading rate was 208～288 meters, was the rapid infiltration system of U.S.'s modular design 1.7～2.4 times of the highest hydraulic loading rate.
2. initial cost is low, running cost is low, maintenance technology is low.Initial cost is 700 00 yuan of/ton water, and handling energy consumption is 0.10 degree/ton water, and processing cost is 0.15 yuan of/ton water, is respectively 1/2,1/3 and 1/3 of conventional secondary biochemical treatment factory or buried secondary biochemical treatment equipment; Operation is simple, and convenient management does not need any mechanical means and professional and technical personnel, and maintenance technology is low.
3. surplus sludge volume is few, floor space is less, secondary environmental pollution is few.Its institute's mud that produces surplus sludge volume behind the soil microorganisms endogenous metabolism is few, and decomposes totally through agron process and mineral process again; Handling 1 ton of required floor space of water every day is 1.5～1.8m
2, only be 1/2～1/4 of soil processing and artificial wet land system, and the floor space of treatment tank can be back to subdistrict greening; Adopt underground drip irrigation mode water distribution and top layer earth backing floriculture plant mode make sewage batch and treating processes in do not contact with air, thereby can not produce environmental health problems such as stink pollution and mosquitos and flies.
4. environmental greening beautify, economic plants output, denitrogenation dephosphorizing.Can be directly treatment tank surface matrix floriculture, even the fresh-cut flowers, both can afforest and beautify treatment tank, can obtain the flowers output of economic worth again, can also improve simultaneously the clearance of nitrogen phosphorus, reach the purpose that the residential quarters sanitary sewage is handled on efficient low-consume ground.
Embodiment: with the every day amount of disposing of sewage 4m
