Description

A kind of compound temperature canopy ecological functions bed
Technical field
The utility model is related to a kind of mud decrement and the methods of Ecological Disposal, and in particular to a kind of compound temperature canopy ecology work( It can bed.
Background technology
Currently, sludge of sewage treatment plant utilizes belt filter press, plate and frame filter press and centrifuge etc. after flocculation improves Dehydration equipment, moisture percentage in sewage sludge can be reduced to 80% or so, but further decrease moisture percentage in sewage sludge to 60% hereinafter, at present compared with Hardly possible is realized.High water content sludge not only increases the transportation cost of sludge, while the sludge of 60% or more moisture content can not also expire The disposition requirements such as the follow-up Sludge landfill of foot, compost and burning.Due to containing a large amount of heavy metal, pathogen and difficulty in sludge Degradation of organic substances and make it using being very restricted, be largely microorganism residuum in solid, organic component accounts in solid 50~80%.Therefore, the main purpose of Treatment of Sludge is the moisture reduced in sludge, reduces sludge total volume, and will be in sludge Organic component stabilization processes.
The existing sludge treatment technique of sewage treatment plant generally comprises concentration, dehydration, anaerobic digestion, aerobic sigestion etc..Specially Sharp CN102515451A discloses a kind of sludge drying filter bed based on artificial swamp, it is the sludge based on a kind of wetland Processing, and cloth mud pipe is distributed in wetland surface, and sludge system surface can retain out sludge and give an offensive smell, be easy to grow mosquitos and flies, Purely higher by ecosystem moisture percentage in sewage sludge, the disposition period is longer, and the treatment effeciency of sludge is relatively low.
Utility model content
Purpose of utility model:In order to solve the above-mentioned problems in the prior art, the utility model provides a kind of multiple Close warm canopy ecological functions bed.
Technical solution:Compound temperature canopy ecological functions bed described in the utility model, including compound Wen Peng and its internal life State is function bed, and the compound temperature canopy is steel frame construction unit, and ceiling is combined closing with high hydrophobicity glass;The ecology work( Energy bed is sequentially distributed bed body reinforcing layer, flyash filtrate process layer from below to up, and coarse gravel drainage blanket, earthworm layer, sludge are placed Layer.
The ecological functions bed surface layout has cloth mud pipe and covers ganoid konjaku taro and Festuca Arundinacea turf.Spring is to planted in fall richness potassium Crop taro (Colocasia esculenta) interplants the Festuca Arundinacea turf of winter sowing enriching heavy metal after harvesting.
It is equipped with antiseepage film above the bed body reinforcing layer, integrate draining pipe is covered with above antiseepage film, integrate draining pipe one end connects Tracheae is connected, the other end connects outlet pipe.
A length of 5~the 10m of steel frame construction unit, width are 3~5m, a height of 2~3m;The high hydrophobicity glass is long It is 50~80cm for 100~200cm, width.When sludge quantity is big, unit combination can be carried out.
The high hydrophobicity glass is the nanometer titanium dioxide Si hydrophobic material that one layer of 0.5~2cm is adhered on simple glass surface layer Material.High hydrophobicity glass is conducive to moisture in the sludge of evaporation and quickly exhausts, and is the Optimizing Reconstruction to simple glass, cost compared with Low, associated materials are added in the generating process of simple glass can simple realization.
The flyash filtrate processing layer thickness is 30~50cm;The thickness of the coarse gravel drainage blanket be 30~ 50cm, coarse gravel grain size are 3~5cm;Described 30~50 compatriots of earthworm layer arrangement love victory earthworm.
The side wall of the compound temperature canopy is equipped with drainpipe, and high hydrophobicity glass lower edge is equipped with collecting tank, the draining tube top Portion is connected with collecting tank, and bottom is connected with integrate draining pipe.
The method for carrying out mud decrement and Ecological Disposal using the compound temperature canopy ecological functions bed, including by moisture content The sludge of 90~98wt% is pumped into regulating reservoir, then imports compound temperature by sludge is intermittent according to the residence time of function bed sludge Canopy ecological functions bed, residence time are 25~48 hours.
When bed body sludge blanket moisture content 45% hereinafter, and thickness reach 15cm or less when, process cycle is completed, and is stopped Only sludge is pumped into, and after sludge scrapes, starts next process cycle.The collection of sludge is carried out by scraper plate and transports outward disposition.
The utility model carries out desiccation by high light transmission temperature canopy to sludge so that sludge water content content reduces and then can be real Further mineralising, the degradation under the action of earthworm layer (compatriot loves victory earthworm) of existing sludge, realizes that minimizing, the moisture of volatilization pass through High hydrophobicity glass carries out water conservancy diversion and effectively collects.Earthworm layer makes original microbial metabolism chain be able to extend and extend, and passes through A series of enrichment and diffusion are synthesized and are decomposed, antagonism and synergistic effect, and the active of enzyme in sludge reduces, and reduces heavy metal Content and promotion pathogen are innoxious, and sludge Soil neutral phosphatase, protease and sucrase active after processing continue to decline, and are The residue that the taro subsequently planted and Festuca Arundinacea turf are further degraded with digested sludge, provides effective support.In this reality Specific plant taro and Festuca Arundinacea turf, one side taro and Festuca Arundinacea are planted in the compound temperature canopy ecological functions bed of novel offer The residue that turf can degrade with digested sludge, on the other hand, the yield of taro and Festuca Arundinacea turf greatly improve.
Flyash filtrate process layer and coarse gravel drainage blanket are mainly that sewage water filtration purification and mud granule intercept, gravel row Water layer setting primarily serves triple role on flyash filtrate process layer:1, the ventilated condition for improving earthworm layer, allows Earthworm can more play the more preferable effect of the degradation to sludge;2, blocking of the sludge to filter layer is prevented, grain size of gravel is big, porosity Greatly, such mud granule is not easy to congestion packing layer;3, grain size of gravel is big, porosity is big, improves taro and tall grass dermatome system The condition of growth allows taro and Festuca Arundinacea turf to be easier to grow, and convenient for growth, space is loose for taro and tall grass dermatome system, It is not easy to generate physical hazard to ecological functions bed body;4, it is quickly exhausted convenient for the moisture in sludge, avoids flooding earthworm layer Influence.
Advantageous effect:Compared with prior art, the utility model has the following advantages:
1, it is total can either to reduce moisture, reduction sludge in sludge for compound temperature canopy ecological functions bed provided by the utility model Volume, and can realize the minimizing of sludge, sludge system surface can be avoided to retain out sludge and give an offensive smell, grow mosquitos and flies, Treated, and the low minimizing degree of moisture percentage in sewage sludge is high.It is planted on compound temperature canopy ecological functions bed provided by the utility model special Fixed plant taro and Festuca Arundinacea turf, can not only improve efficiency of sludge treatment, additionally it is possible to so that the production of taro and Festuca Arundinacea turf Amount greatly improves.
2, have and do not produce up to 90% or more using the mud decrement rate in method treated sewage provided by the utility model Raw secondary pollution, easy to operate, investment is low with operating cost, adapts to the advantages that wide, economic benefit, environmental benefit and society's effect It is beneficial good.
