Description

A kind of belt domestic refuse sludge dewatering equipment
Technical field
The utility model relates to a kind of sludge dewatering equipment, especially relates to a kind of for the belt type dewaterer through the domestic refuse sludge dewatering after the citric acid drip washing.
Background technology
At present, along with improving constantly of rapid development of economy and standard of living, domestic waste is just with 8% speed increase.Domestic waste comprises domestic garbage, public place and street cleaning rubbish, commercial domestic refuse etc., and its main component is that kitchen excess, waste paper are opened, plastic waste, useless fabric, cullet, vegetation, dirt etc.These domestic refuses not only cause the great wasting of resources, more seriously cause environmental pollution, such as soil pollution, atmospheric pollution, life water source pollution etc.
The method of processing domestic refuse mainly contains landfill method, burning method and compost treatment.
Landfill method be exactly with consumer waste filling and embedding in refuse landfill, advantage is that cost is low, method is simple; Shortcoming is that occupied ground is large, produces percolate, causes groundwater pollution, produces methane and easily causes blast.
Burning method can make the garbage weight after the burning reduce 75%~95%, only accounts for about 0.1m after the waste incineration per ton 3, the residue lime-ash stable in properties after the burning can be utterly destroyed pathogenic bacteria, burns the heat that produces and can be used for heat supply and generating, reclaims the energy.But the atmospheric polluting materials such as the waste gas that the method produces, malicious dirt still have larger destructive force to environment.
Composting process is to utilize the activity of microorganism with the perishable organic substance decomposing in the rubbish, is transformed into to be rich in organic and nutritive element and the micro-organic fertilizers such as nitrogen, phosphorus, potassium.Heavy metal mainly contains copper, zinc, lead, chromium, cadmium, nickel, mercury etc. in the compost.The part heavy metal concentration surpasses national standard in the farm crop if compost without the removing heavy metals processing, then can make in the excessive situation of amount of application.
The scientist of USDOE Brooker Hei Wen National Laboratory has invented a kind of novel method of utilizing citric acid to remove pollutent in soil and the rubbish, it can remove common toxic metal cadmium, lead, zinc, copper and radioactive substance nearly all in soil and the rubbish, such as uranium, thorium, platinum, cobalt, caesium and strontium.This acid can be attached on plain metal and the radioactive substance and form compound.
Using the benefit of citric acid is that it is very little to the destructiveness of soil, and rests in the soil with can't be permanent.Soil " was washed " to be crossed behind the soil just substantially near normal level.The natural bacteria of then surviving in the soil is added to " washing " again and crosses in the citric acid solution of soil.Soil bacteria several citric acid metal compounds of can degrading make this this metal separate to reach the purpose of recycling from solution.
The used citric acid of this method can also utilize again.Utilize this method can remove in the polluted soil 99% uranium, plumbous and other toxic metal of 95%.
The Gao Yan of Hua Zhong Agriculture University levies etc. organic acid is also found the desorb of Cadmium in Soil and the experiment of influence factor, but add cadmium and trace element in the citric acid activating soil, increased the solubility of cadmium in the soil solution, and the stability of the organic double compound that forms because of it and cadmium is lower than Cd-EDTA, easy decomplexing in the soil solution.
Can effectively remove wherein heavy metal although utilize citric acid solution that rubbish mud is carried out drip washing, however large through the rubbish sludge moisture content after the drip washing, can not be directly used in compost or produce fertilizer, also to pass through processed.There are various sludge dewatering equipments in the prior art, but not specially for dewatering unit after the drip washing of rubbish mud process citric acid, efficient, cheap.Rubbish mud has the characteristics of himself, and macrobead wherein is many, and it is many for example to contain building waste cement block, glass, metal, wooden unit, and technique is more complicated than general waterworks sludge dehydration when therefore dewatering.And water extracter of the prior art is mostly relatively more expensive, and operation, maintenance, maintenance be difficulty relatively.Therefore, the utility model is devoted to propose a kind of water extracter, its Main Function is the free water of sloughing acid group counterweight metal complex in the rubbish mud, the flowability of mud is reduced, prepare for further making fertilizer, it can not only remove the water in the rubbish mud rapidly, and low cost, production, easy maintenance.
Domestic waste is through after preliminary treatment, citric acid drip washing, dewatering, carry out further again compost or for the production of fertilizer, this can produce huge economic benefit and social benefit, is conducive to the development of Environmental Protection in China cause, is the cause of benefiting the nation and the people.
