Description

The treatment process of a kind of suitable water-deficient area percolate from garbage filling field

Technical field

The present invention relates to a kind of treatment process of high-concentration sewage, specifically, adopt multi-stage biochemical to handle and recharge combination technique and carry out harmless treatment, can realize the zero release of percolate at the water-deficient area percolate from garbage filling field.

Background technology

Percolate is the high concentration organic sewage that rubbish produces in the landfill process, is mainly derived from the interior moisture of precipitation, organic matter degradation and rubbish itself.Be subjected to influence of various factors such as rubbish composition, quantity of precipitation, landfill yard structure, landfill time, the water yield of percolate changes greatly, water quality situation complexity.Have following characteristics:

(1) organic concentration height, the BOD in the percolate 5Reaching as high as several ten thousand mg/L with COD concentration, mainly is to produce in the acid fermentation stage, and pH reaches or a little less than 7, BOD 5With COD ratio be 0.5~0.6.

(2) heavy metal content height contains more than ten kind of metal ion in the percolate, wherein iron and zinc are higher in the acid fermentation stage, and the concentration of iron can reach about 2000mg/L, and zinc concentration can reach about 130mg/L.

(3) change of water quality is big, and the water quality of percolate depends on the make of landfill yard, the kind of rubbish, quality, quantity and the length at landfill age, and wherein the make of landfill yard is the main factor that influences percolate water quality.

(4) ammonia nitrogen concentration in the high percolate of nitrogen content increases along with the increase at garbage loading embeading age, can be up to about 2500mg/L.And when ammonia nitrogen concentration is too high, can influence microbic activity, reduce the effect of biological treatment.

(5) nutritive element is out of proportion, BOD in the general percolate 5/ P is mostly greater than 500, and the phosphoric rational proportion required with microorganism growth differs bigger.

(6) contain more hardly degraded organic substance.

Detect data presentation, contain 93 kinds of objectionable impuritiess in the percolate, 22 kinds of emphasis control lists that have been put into China and American National Environmental Protection Administration are wherein arranged, wherein a kind can be directly carcinogenic, 5 kinds can be brought out carcinogenic.Refuse landfill design, operation and management problem demanding prompt solution are effectively controlled and be treated as to percolate as a kind of concentration height, big, the difficult sewage of degrading of toxicity to it.

Domesticly according to investigations built refuse landfill and mostly adopt conventional sewage disposal technology to carry out percolate to handle poor effect.Therefore people constantly explore special treatment technology at percolate, and total development trend is the application of new and high technology in the water technology.As disclosing a kind of combination biological treatment in the CN1544356 patent document.The CN1478737A patent document discloses electrolytic oxidation+ceramic membrane biochemical treatment and separation+reverse-osmosis treated technology.Both at home and abroad to the achievement in research of refuse leachate treatment technology, mainly there is following several problem before making a general survey of:

(1) common process is difficult to adapt to high density, the difficult degradation characteristic of percolate, and treatment effect is difficult to guarantee;

(2) some COMBINED PROCESS route complexity, structures are more, and construction investment is big, the operational management difficulty;

(3) some special process equipment manufacturing cost height, operation energy consumption are big, and the processing cost height is applied difficulty;

In addition, China is vast in territory, and various places weather condition difference is big.The dry quantity of precipitation in the north and hinterland is little, and the generation of this area's percolate is lower.And do not specialize in and develop corresponding treatment technology as yet both at home and abroad at present at water-deficient area leachate quality, water yield characteristic expansion.

Summary of the invention

The invention provides the treatment process of a kind of suitable water-deficient area percolate from garbage filling field.To solve the problem that treatment effect is bad, method is complicated, cost is high that exists in the percolate from garbage filling field processing of water-deficient area.The technical scheme that the present invention takes is: comprise the following steps:

Six, sludge treatment: aerobic system excess sludge and sludge from sedimentation tank enter sludge treating system, adopt plate and frame(type)filter press, and Yu Shui is back to equalizing tank, and dewatered sludge landfill is gone into waste layer;

Seven, recharge: adopt recharge system, comprise the sterilization pre-treatment, recharge, recharge system comprises: the pond, recharge pump, water-transmission line, shower nozzle.

Sterilization pre-treatment: pass through disinfection by chlorine dioxide; Kill virus and bacterium in the percolate on the one hand, can effectively alleviate on the other hand because of the bacterium algae multiplies the shower nozzle that recharges that causes and stop up.

Recharge: the number of times of batching is 4~7 times/d, hydraulic load 12~20L/m 2D, the COD 60~80g/m that loads 2D.

It is a kind of effective treatment process that processing is sprayed in the circulation of percolate, is mainly reflected in two aspects.The one, decrement, the spray of returning of percolate can be by evaporating or being absorbed by vegetation, and the treatment capacity outside the venue of minimizing percolate reduces the investment that percolate is handled.The 2nd, quicken the stabilization process.By recharging the water ratio that can improve waste layer, increase the humidity of rubbish, strengthen microbic activity in the rubbish, quicken methanogenic speed and organic decomposition, shorten the stabilization process of landfill waste.By reflux cycle, the BOD of percolate 5Can drop to 30~350mg/L and 70~500mg/L respectively with COD.

In addition, can also improve water-deficient area garbage loading embeading layer water ratio, quicken organic decomposition in the rubbish, shorten the stabilization process of landfill waste, make the stabilization process of former need 15 years~20 years foreshorten to 2 years~3 years by recharging.

Adopt the mode treating refuse percolate of circulated backfilling need consider the climate hydrologic condition, factors such as the number of times of batching, hydraulic load and COD load.Generally need determine, and the amount of recharging should improve along with the process of waste layer stabilization according to the test of landfill yard practical situation.The present invention determines that by testing optimum condition is: the number of times of batching is 4~7 times/d, hydraulic load 12~20L/m 2D, the COD 60~80g/m that loads 2D.The degradation efficiency of COD and BOD is reached respectively about 70% and 75%, and the percolate decrement also can reach more than 70%

The present invention compares with existing technology, pointed stronger, the advantage such as stability is higher, initial cost and operation cost are lower of this method.Especially along with the continuity of working time, the percolate decrement effect of recirculation process is progressively brought into play, finally can realize the zero release of percolate, controls its pollution.
