Abstract
The invention relates to a conditioner and the application in sludge composting thereof, relating to a conditioner and the application thereof. The invention solves the problems that the existing conditioner is large in dosing quantity, easy to be decomposed, low in mass transfer efficiency, difficult to be recycled and easy to have anaerobic acidification. The conditioner is pumice with the grain diameter of 0.2 cm to 10 cm. The conditioner has the following applications: firstly, the conditioner is mixed with sludge so as to obtain a mixing material; secondly, the mixing material is put in a fermentation apparatus to carry out fermentation; thirdly, material is discharged after fermentation, then the conditioners is sieved out, namely, the application of the conditioner in sludge composting is finished. The dosing quantity of the conditioner is decreased by 30 percent, and the space structure thereof is stable, and the conditioner is not easy to be decomposed, high in mass transfer efficiency, able to be recycled and not easy to have anaerobic acidification.
Description
Technical field
The present invention relates to a kind of amendment and application thereof.
Background technology
The a large amount of mud that produce in the sewage treatment process, its organic content height, water ratio is big, degradation cycle is long, easily corrupt, stink is big, easily polluted underground water, grow mosquitos and flies, become the solid waste that influences environment, must give rational ultimate disposal.The method of sludge disposal has burning, sanitary landfill, compost etc., and wherein aerobic compost can be realized minimizing, stabilization, innoxious, the resource utilization of mud synchronously owing to it, thereby is subject to people's attention day by day.
At present, sewage work's dehydrated sludge water ratio height, porosity is low, easily compacting in the aerobic composting process, sticking separating has a strong impact on the mass transfer of oxygen, thereby need add a large amount of amendments.And amendments such as traditional wood chip, stalk, straw not only self easily decompose in composting process, need to consume extra oxygen, and carrying out along with composting process, the degradation of supported hole gap structure, the heap compacting phenomenon of collapsing is obvious, and mass transfer usefulness descends.The anaerobic acidification problem easily takes place in the sludge composting process, and sour environment can obviously reduce microbic activity, prolongs the compost cycle.These organic amendments are difficult to recycle in addition, have increased the become thoroughly decomposed volume of back product and the usage quantity of amendment, the development of restriction sludge aerobic compost technology.
Summary of the invention
The present invention seeks to big for the dosage that solves existing amendment, self easily decomposes, mass transfer usefulness is lower, difficulty recycles and the problem of anaerobic acidification easily takes place, and provides a kind of amendment and the application in sludge composting thereof.
Amendment of the present invention is that particle diameter is the float stone of 0.2～10cm.
The applying step of amendment in sludge composting is: one, press mass ratio and 1: 0.3～4 mud mixed with amendment, mixture; Two, mixture is put into the fermentation equipment fermentation, and the mixture piling height is 0.8～2.5m, and rate of venting is 0.05～2m
3/ minm
3, fermenting, to regulate rate of venting when the mixture temperature is higher than 65 ℃ be 0.05～8m
3/ minm
3, keep the mixture temperature and under 50～65 ℃ of conditions, kept at least 5 days, wherein keeping 3 days temperature at least is 55～65 ℃; Three, amendment is sieved out in fermentation discharging after 10～20 days then, promptly finishes the application of amendment in sludge composting; Wherein the water ratio of mud is 65%～85% in the step 1, organic content 35%～80%.
Amendment can be applied to separately in the sludge composting among the present invention, compares traditional amendment, and its consumption has reduced 30%, and amendment can sieve out 96% after the fermentation discharging, recycles after airing, and rate of loss is low, reduces the running cost of sludge composting.Simultaneously fermentation time had one month by the conventional high-temperature composting process to shorten to 10～20 days, and had significantly improved the intensification and the cooling rate of heap body, and the fermentation first day heats up and can reach 25.5 ℃, and the heat-up rate of traditional technology generally only is 8～14 ℃/day.Owing to improved mass-transfer efficiency, shortened fermentation period, be difficult for anaerobic acidification takes place, will reduce material fermentation power consumption, energy-conservation nearly 40%.Amendment is the splendid inorganics of ventilation property among the present invention, in compost, be difficult for decomposing, space structure is stable, improved air in the intravital mass-transfer efficiency of heap, reduced the requirement of decomposition such as traditional amendment wood chip, stalk and straw to air, the water-intake rate of amendment can reach more than 40% among the present invention simultaneously, can reduce the water ratio of mud, improve the permeability of material integral body, and the pH value that can effectively regulate mixture is 7.2～8.8, for microorganism is created the suitableeest easy survival environmental conditions.Amendment of the present invention is used products obtained therefrom and is had advantages such as organic composition height, trace element abundance, fertilizer efficiency long action time in sludge composting, be splendid organic slow-release fertilizer of a kind of fertilizer efficiency and soil improvement agent.
