Abstract
The invention discloses a device for semi-aerobic dry fermentation of sludge and feces mixture, which comprises a base with a slope, wherein an HDPE anti-seepage membrane is arranged on the base, a gas-permeable main pipe and gas-permeable branch pipes are arranged on the HDPE anti-seepage membrane, the gas-permeable branch pipes are perpendicularly connected on the two sides of the gas-permeable main pipe respectively, the gas-permeable main pipe and the gas-permeable branch pipes are all buried in cobblestones, compost fermentation raw materials are put on the cobblestones, sludge composting products which are formed by compost fermentation are arranged on the compost fermentation raw materials, and a water collection pit is formed below the slope of the base. The device adopts the gas-permeable pipes at the bottom to supply oxygen to reduce the blast aeration cost and save the electricity cost. The fermented products are put at the top of the device to biologically remove the odor from the bottom fermentation raw materials by virtue of microorganisms in the fermented products, resulting in odor removal. Besides, the device can utilize light to increase the dehydration speed, so as to achieve synchronization of fermentation and dehydration.
Description
Technical field
The present invention relates to the environment treating sludge, be specifically related to a kind of mud and ight soil and mix accurate aerobic mummification fermentation unit.
Background technology
At present, along with industry and development of city, treatment rate of domestic sewage improves day by day, activated sludge process be use in the WWT the most extensively, proven technique, the sewage work in the whole world nearly 90% adopts this method as core technology.The disadvantage of activated sludge process is to produce a large amount of excess sludges, and moisture percentage in sewage sludge is high, the dehydration difficulty, and processing costs is expensive.The processing of mud and disposal costs account for 25% ~ 40% of sewage work's overall running cost, even up to more than 60%.Along with expanding economy, the municipal sewage plant is more and more, produces a large amount of mud, is difficult to treatment and disposal, and causes huge processing burden.These moisture percentage in sewage sludge are high, and landfill is undesirable, and incinerating combustion value is low, add fuel; With high costs being difficult to bears, as the scent of that ferments, and be bigger to surrounding environment influence, so the present invention is primarily aimed at original fermentation unit shortcoming; Research and develop accurate aerobic compost drying bed, accelerated fermentation rate, improved the moisture removal rate; And, improve the fertilizer fertilizer efficiency through the sneaking into of ight soil, reduce smell and produce.
Summary of the invention
To the deficiency of prior art, the purpose of this invention is to provide a kind of mud and ight soil and mix accurate aerobic mummification fermentation unit, make relative traditional zymotic device can reduce the blast aeration expense, avoid whole anaerobically fermentings, reduce stink and produce.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention realizes through following technical scheme: mud and ight soil mix accurate aerobic mummification fermentation unit; Comprise a base with a slope; Lay the HDPE anti seepage membrane on the said base earlier, be equipped with ventilative person in charge and ventilative arm on the said HDPE anti seepage membrane, said ventilative arm is vertically connected on said ventilative person in charge both sides respectively; And the placement pebbles all buries the said ventilative person in charge and said ventilative arm; Stack the compost fermentation raw material on the said pebbles, repave the sludge composting finished product that compost fermentation is good on the said compost fermentation raw material, the sloping end of said base, be provided with a catch pit.
Further, the gradient i=1%-5% of said base.
Further, the thickness of said pebbles laying is 20-50cm.
Further, said fermentation raw material is mud, ight soil or its mixture.
Further, this device also is equipped with weather cloth, adopts when raining.
Principle of the present invention is: relative traditional zymotic device, the present invention has reduced catchmenting and water-freeing arrangement of bottom, is put in a side and will collect water device (catch pit), and utilizes the gradient to collect.This bottom of device is installed ventilative pipeline, and one places on the catch pit water surface, thereby makes air to get into the fermented manure device through pipeline, so promptly can reduce the blast aeration expense, has avoided whole anaerobically fermentings again, has reduced the stink generation; The compost finished product that has fermented is laid at the fermentation raw material top, and utilizing wherein, mikrobe reduces stink and produces the stink biodegrade of submerged fermentation volatility of raw material.This device can also utilize illumination to accelerate rate of water loss.
The invention has the beneficial effects as follows:
1, the aerobic or anaerobism of traditional compost fermentation unit, aerobic effective, speed is fast, but the electric lighting bill is heavy, and stink is big, and the present invention utilizes the ventilative pipeline in bottom to carry out oxygen supply, reduces the blast aeration expense, has practiced thrift the electricity charge;
2, the finished product that fermented is laid at this invention top, and utilizing wherein, mikrobe reduces stink and produces the stink biodegrade of submerged fermentation volatility of raw material;
3, this device can also utilize illumination to accelerate rate of water loss, fermentation mummification simultaneously.
Above-mentioned explanation only is the general introduction of technical scheme of the present invention, understands technique means of the present invention in order can more to know, and can implement according to the content of specification sheets, below with preferred embodiment of the present invention and conjunction with figs. specify as after.Embodiment of the present invention is provided by following examples and accompanying drawing thereof in detail.
