Abstract
The invention relates to a method for treating urban domestic sludge by earthworms, which comprises the following steps: (1) selecting earthworm variety, namely selecting one or two of Eisenia foetida and micro double-chest earthworms, and mixing according to the weight ratio of 1 to 1 for standby; (2) domesticating the earthworms, namely, under room temperature, feeding earthworms according to 0.4 to 0.5 kilogram feed per kilogram of earthworm each day in the first month, wherein the feed is a mixture of dehydrated sludge and wheat straw which are mixed evenly according to the weight ratio of between 15 to 1 and 20 to 1; and then adding the dehydrated sludge accounting for 1 to 2 percent of the total weight of the feed into the feed month by month from the second month, till feeding the earthworms totally by the dehydrated sludge; and (3) feeding the earthworms by the dehydrated sludge, under the conditions that temperature is between 10 and 28 DEG C and humidity is 70 to 80 percent, feeding the domesticated earthworms based on 0.4 to 0.5 kilogram of the dehydrated sludge per kilogram of the domesticated earthworms per day, wherein the feeding amount for once is the amount for seven days; and feeding the earthworms again when the fed sludge becomes muckworm totally. The method can shorten treatment time, reduce loss of nitrogen, and obtain high-quality organic fertilizer and efficient adsorbent, namely the muckworm.
Description
Technical field
The present invention relates to the sludge treatment technology in the field of environment protection, relate in particular to a kind of method of processing city life sludge by using angleworm.
Background technology
Municipal sludge is meant the product of sewage treatment plant residual mud after processed.Adopt microbial fermentation to handle domestic sludge, and the making fertilizer is a kind of good method of effectively utilizing organic waste, it can handle domestic sludge effectively, avoid environmental pollution, and the organic substance in the mud can also be changed into nutritive substances such as the required nitrogen of crop, phosphorus, potassium, make organic waste be able to recycle.But in fermentation process, can lose the nitrogen in the part mud, the smell that fermenting process produces also can produce certain detrimentally affect to surrounding environment.
It is not rarely seen that earthworm is handled organic waste, then do not report but be used for directly handling municipal sludge.Chinese patent 200710039963 discloses a kind of method that adopts treating sludge by earthwork stacking, this method is that the mud composting is placed on temperature is 25 ℃, and atmospheric moisture is in 75% the environment, to its fermentation finished thoroughly1, earthworm is seeded in Sludge Surface, makes the inoculum size of earthworm reach 0.1/gram; Its treating processes in two steps, the one, fermenting process, the 2nd, introduce a fine variety.But this method is in order to make mud stable, and fermenting process needs 8～16 days, and is consuming time longer, and fermenting process also can lose the nitrogen in the part mud.
Summary of the invention
Technical problem to be solved by this invention provides a kind of shortening treatment time, the method for the processing city life sludge by using angleworm of the loss of minimizing nitrogen.
For addressing the above problem, the method for a kind of processing city life sludge by using angleworm of the present invention may further comprise the steps:
(1) selecting for use of earthworm kind: select a kind of in Eisenia foetida, the small Lumbricidae Bimostos for use or two kinds of weight ratios by 1:1 are mixed the back stand-by;
(2) domestication of earthworm: at room temperature, first month by every day the per kilogram earthworm add 0.4～0.5 kilogram of feed and feed, wherein said feed is dewatered sludge and the wheat straw mixture by the weight ratio uniform mixing of 15:1～20:1; In feed, increased the weight of dewatered sludge then month by month since second month, until all feeding with dewatered sludge in 1～2% ratio;
(3) mud of throwing something and feeding: the earthworm after will taming is that 10～28 ℃, humidity are under 70～80% conditions in temperature, by throw something and feed 0.4～0.5 kilogram of dewatered sludge of per kilogram earthworm every day, the amount of once throwing something and feeding 7 days; When the mud of throwing something and feeding all becomes the earthworm excrement, throw something and feed again.
The method of 2 processing city life sludge by using angleworm as claimed in claim 1 is characterized in that: the dewatered sludge water ratio in described step (2), (3) is 60%～70%.
The present invention compared with prior art has the following advantages:
1, because the present invention need not any middle-chain, directly with the municipal sludge after the earthworm processing dehydration, therefore the nitrogen content of handling back earthworm excrement is high by 20%～30% than the become thoroughly decomposed nitrogen content of fertilizer of sludge fermentation, thereby has avoided the drawback of fermentative processing mud effectively.
2, the present invention utilizes earthworm to organic degradation characteristic, realize innoxious, the stabilization and the resource utilization of mud, also can obtain high protein feed---earthworm simultaneously, high-quality fertilizer and high-efficiency adsorbent---the earthworm excrement, turn waste into wealth, meet the era development requirement of energy-saving and emission-reduction, recycling economy.
3, adopt method of the present invention can simplify the treating processes of municipal sludge, every kilogram of earthworm day is handled 0.45～0.50 kilogram in mud, and processing costs is low, non-secondary pollution.
