Description
[technical field]
The present invention relates to a kind of treatment process of sewage sludge, be specifically related to a kind of technical field of using wood chip as the treatment process of the sewage sludge of flocculating aids.
[background technology]
In order to administer the pollution of sewage to environment; The sewage treatment facility that all trades and professions have all been set up the different process route to be to realize qualified discharge, is that the sewage treatment facility of the processing organic wastewater of core process (being commonly called as " anaerobic and aerobic " treatment process) has occupied lion's share with " microbiological deterioration " wherein.This technology has the characteristics that treatment of Organic Wastewater is up to standard that are easy to; But in treating processes, can produce a large amount of mud; According to the service experience of beer enterprise, one ton of COD of every explanation (COD) can produce 2～3 tons of water ratio and reach the mud (the different sludge outputs of industry are slightly variant) about 85%.At present, these mud major parts have been taked landfill disposal, have caused second environmental pollution.
The reason that causes this secondary pollution is because this mud is actually deactivated anaerobism or aerobic bacteria, and its moisture mainly is present in the cell of bacterium and is not easy to take off.Widely used at present " belt filter press " can only be taken off external free water content; Being present in intracellular moisture can't remove; Even so the water ratio of mud adopts other powerful mechanical expression (using plate and frame mechanism filter-pressing machine has been very common technology to material dewatering), exposure in sunshine or natural air drying method still can't further reduce water ratio still up to 75～85% (industry different water cut rate is also different) after the press filtration of process belt.
But this mud is not refuse; Per kilogram contains the calorific value (the different calorific values of industry are variant) of 1000～2000 much cards (4000～8000 KJ) in its over dry material; Also contain several organic matter and nitrogen phosphorus potassium to tens percentage points; If its moisture is reduced to below 25%, then both can have done fuel and burn.Also can do the aggregate of organic composite fertilizer.The sole cause that influence is used be water ratio surpass 25% just the extra energy of needs evaporate redundant moisture, uneconomical economically.
In order further to remove intracellular moisture, water ratio is dropped to utilizable economically degree, mainly contain three kinds of technology at present:
First kind of technology is directly with its oven dry with the way that heats; Mainly contain high temperature oil heating, drying, fluidized-bed and modes such as liquid bed oven dry and cylinder oven dry; These technology have obtained using widely in the manufacturing enterprise of the discharging that has surplus heat (for example boiler exhaust gas or Industrial Stoves exhaust), can drop to water ratio below 10%.The shortcoming of this technology has two: the one, and power consumption is very high, but can not (for example municipal sewage plant) use in the place that does not have waste heat.
Second kind of technology be use mechanism filter-pressing again after adopting the way of adding chemical agent that cell walls is destroyed mode with moisture removal; Can water ratio be dropped to below 30%; This is maximum technology of studying at present; Do not having the utilizable place of waste heat to use on a small quantity, its shortcoming is that chemical agent is expensive, if there is not government subsidy to lose money.
The third technology is that first mud with water ratio about 85% is heated to certain temperature fermentation for some time; Add and carry out mechanism filter-pressing or oven dry again after a spot of chemical agent thoroughly destroys cell walls; This technology is commonly used abroad, domestic use rarer, and major cause is that initial cost is too big; Move bad control, and energy remains loss.
[summary of the invention]
For solving above deficiency; The present invention provides a kind of method with the wood chip sewage sludge can sludge water content be reduced to the degree that can not lose money economically; Utilize and the elimination secondary environmental pollution so that it is turned waste into wealth, these method energy-conserving and environment-protective have very strong practicality.
The technical scheme that the present invention adopted is: a kind of method with the wood chip sewage sludge is characterized in that earlier the interpolation lime white is adjusted to pH value more than 7 in the mud mixture of water ratio 85～98%; After adding 5～10% wood chip (wood chip granularity ≯ 100 micron) again and stirring; Pump into and carry out the mechanical expression dehydration in the plate and frame(type)filter press; Moisture is squeezed 50～60% to be drawn off; Can adopt the mode of exposure in sunshine or natural air drying further water ratio to be dropped to then and carry out recycle below 25%, also can unite use with the waste heat dryer.
A kind of its characteristic of method with the wood chip sewage sludge, described mud mixture are alkalescence need not add lime white adjustment pH value.
Ultimate principle of the present invention is: the wood chip particulate can squeeze most mud cell wallss broken in expressing process by mechanical pressure, wood chip can also play the effect of filter bridge simultaneously, makes the interior moisture of born of the same parents become free water content and through filter cloth it is extruded.Because wood chip is a kind of material of cheapness, is easy to obtain, thereby has substituted the drying mode of highly energy-consuming and expensive chemical mode.Under the identical situation of dehydration rate, but use present method than waste heat furnace drying method energy efficient 90%; Than chemical process cost-saved 80%; Can practice thrift investment 70% than thermophilic fermentation method.
Special benefits of the present invention is: in the industry that has waste wood to produce, the waste wood that produces in the production process can use equally and effect identical.
In the utilizable place that has surplus heat, but present method is united use than using waste heat furnace drying method energy efficient about 50% separately with the waste heat furnace drying method.
Do not having the utilizable place of waste heat (for example municipal sewage plant), using present method earlier sludge water content to be squeezed about 50%,, can moisture dropped to below 25% equally again through exposure in sunshine or natural air drying.
Wood chip is a kind of nontoxic material, and admixture is used as fuel in mud still be that the compoiste fertilizer aggregate all has no detrimentally affect.
Beneficial effect of the present invention: adopt the sewage sludge treatment method energy-conserving and environment-protective of wood chip as flocculating aids, economical and effective has very strong promotion effect.
