Description
Technical field
The present invention relates to a kind of municipal sludge innocuity disposal system, and utilize this treatment system to handle the method for innocent treatment of mud.
Background technology
Produce a large amount of mud in the sewage treatment process, its quantity accounts for about the 0.3%-0.5% that handles the water yield (in water ratio 97%).The processing investment and the running cost of mud are very huge, and the expense that is used for sludge treatment accounts for the 20%-50% of sewage work's working cost,, brought white elephant to sewage work.At present, traditional method is to nurse one's health by dosing coagulant, coagulant aids, mechanical dehydration is handled then, form water ratio and be 70%～80% mud cake outward transport carrying out sanitary landfill, burning disposal, fermentation composting, this mode because of water ratio too high to landfill yard surrounding enviroment and treatment effect brings extremely adverse influence or need further drying can enter just that incinerator is handled and the fermentation composting.So, it would be desirable before mud outward transport, be controlled at below 60% in mud moisture, not only reduce outer freight volume over half, and 60% following mud is essentially solid-state, do not produce percolate, can directly advance landfill yard.Can reduce the fermentation period of half if carry out compost treatment, increase economic benefit.Dried mud cake can also be made solid fuel, directly carries out burning disposal after allocating.
The high major cause of mud water ratio behind mechanical dehydration can't all be extruded by the pressure of traditional mechanical dehydration because of biological cells in sludge and colloid contain a large amount of " interstitial waters " (account for all aqueous 70%), be the mucilage shape when moisture percentage in sewage sludge is between 60%-65% simultaneously, water molecules is wrapped up by one deck colloid, this zone is referred to as mud " viscose glue phase region ", be the most difficult stage of sludge dewatering, the method for gathering around traditional mechanical dehydration is difficult to further remove.So, must take special means to crack intercellular structure and mud " viscose glue phase region ", make part " interstitial water " be discharged from, pass through the mode filtering of mechanism filter-pressing again.
The sludge treatment and the equipment working cost of above technology are all higher, generally more than 200 yuan/ton.And, equipment cost higher as: high temperature mummification, mechanical mode and hyperacoustic equipment input are all higher, generally in ten thousand yuan of/ton mud/skies of 5-10, are difficult to extensively be promoted.
In addition, in sludge handling process, produce harmful exhausts such as Dioxins simultaneously as the high temperature drying technology, environment is produced secondary pollution.Carry out cell wall breaking with machinery and hyperacoustic technology, except the equipment input greatly, need consume a large amount of electric power during operation.So working cost is big.
Adopt strong oxidation medicament to carry out mud cell wall breaking method, because the sludge concentration height of 80% water ratio, medicament is difficult to fully merge, and addition is big, and cost is also high.After having added chemical agent, may bring unfavorable factor to the subsequent disposal of mud.
