Abstract
The invention discloses efficient mixed flora for treating sludge which comprises comamonas testosteroni, pseudomonas alcaligenes, stenotrophomonas rhizophila, pseudomonas pseudoalcaligenes and azospirillum. The mixed flora can effectively decompose the sludge.
Description
Technical field
The invention belongs to technical field of sludge treatment, particularly to a kind of high efficient mixed flora for lignin-sludge.
Background technology
The process of China's municipal sewage adopts activated sludge process mostly, and it has the advantage of capital expenditure province, high treating effect, but it exists a maximum drawback always, that is, can produce substantial amounts of excess sludge in running. Excess sludge usually contains more poisonous and harmful substance and the Organic substance of non-stabilisation, if not carrying out appropriate process and disposal, it will environment causes direct or potential pollution. In traditional activated sludge process, degraded 1kgBOD5 (biochemicalOxygenDemand, five-day BOD) excess sludge of about 15 100L can be produced, for processing or the expense for the treatment of excess sludge accounts for 25% the 65% of sewage disposal total cost. Along with promulgation and the enforcement of some new Environmental Laws, wastewater treatment effluent quality being required strict all the more, the yield inevitably resulting in excess sludge is increasing, it is therefore apparent that processing of mud will become a great problem of environmental area with disposing.
At present, the sludge reduction technology of research mainly has ozonation technology, ultrasonic disruption cell technology, solves coupling technology, soda acid dissolving technology etc. both at home and abroad, but there is cost height or technical bottleneck, it does not have form the application of certain market. Current sewage treatment plant sludge output scale highlights with the incomplete contradiction of sludge reduction, Treatment of Sludge and disposal technology greatly. The Reduction Technology of mud is by adding specific mixed bacterial by mixed bacterial, reaches to improve organic decomposition function. The Reduction Technology of mud can be reduced sludge treatment investment and operating cost by mixed bacterial, can optimize sludge organism phase and solid-liquid separation effect. More long according to ecological theoretical food chain, the ratio that energy is consumed in transmittance process is more big, ultimately forms total Biomass also more few. Therefore, the predation of mixed bacterial and predation at the same level all can reach to reduce the purpose of excess sludge generation amount. Therefore, the mixed bacterial Reduction Technology to mud can be passed through to mud Sources decreasing or excess sludge reduction, for a large amount of construction of current sewage treatment plant residual sludge-tank, and excess sludge be carried out minimizing.
