Abstract
The invention relates to a method for producing a maggot protein and a sludge-based soil modifier by treating activated sludge, which is characterized by comprising the following steps: (1) selecting the breed of maggots; (2) filling activated sludge in a container, inoculating the maggot, culturing at the culture medium temperature of 20-35 DEG C under the ambient relative humidity of 60-80% for 3-10 days, separating the maggots, drying the maggots to obtain a dried product, and pulverizing the dried product to obtain the maggot protein; and (3) composting the residual solid substance separated from the maggots in a sealed environment at 15-35 DEG C for 3-10 days to obtain the sludge-based soil modifier. The invention effectively overcomes the defects in the fermentation treatment of sludge, simplifies the treatment process of residual sludge, stabilizes and recycles the sludge to change the sludge into harmless substances, can obtain a high-protein feed, and does not produce secondary pollution.
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 ecotechnology and handle the method that active sludge is produced fly maggot protein and mud base soil improvement agent.
Background technology
Active sludge is meant the product of sewage treatment plant residual mud after processed.The organism that wherein contains the needed nutrient of plant growth such as a large amount of nitrogen, phosphorus and can improve Soil structure if in addition fine utilization will cause huge pollution to environment, also is a kind of waste of resource simultaneously.At present, to the treatment process of urban wastewater treatment firm excess sludge, anaerobic sludge digestion technology and sludge aerobic digestion process have generally been adopted both at home and abroad.These two kinds of technologies all can make the nitrogen element loss in the mud, and also can produce bad smell simultaneously influences surrounding environment.The present invention introduces fly maggot in the active sludge, makes full use of its ecology and biological characteristics, brings into play its physiology metabolic function, realizes recycling sludge, innoxious and stabilization.The inventive method has solved a sludge disposal difficult problem in the urban wastewater treatment firm production simultaneously, is the important way that realizes that the mud agricultural utilize, and also is the important channel of realizing the cities and towns target of sustainable development.
It is not rarely seen that ecotechnology is handled active sludge, then do not report but directly handle active sludge with fly maggot.The patent of invention of Gui Changhua, Sun Ying (number of patent application: 200710039963.2) disclose a kind of method that adopts treating sludge by earthwork stacking, it is 25 ℃ that this method is placed on temperature with the mud composting, 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.The patent of invention of Fu Xiaoyong, Chen Xuemin, Huang Kui (number of patent application: 200810181293.2) disclose the method for processing city life sludge by using angleworm.This method selects for use one or both mixed by 1:1 in Eisenia foetida, the small Lumbricidae Bimostos to tame; The domestication process adopts and to increase the method that mud and wheat straw ratio are fed gradually, until using the dewatered sludge nursing fully; Is that 10 ~ 28 ℃, humidity are under 70 ~ 80% conditions with the earthworm after the domestication in temperature, and 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, is thrown something and fed again.These two kinds of methods all need mud is carried out pre-treatment, and are consuming time longer.
Summary of the invention
Technical problem to be solved by this invention provides the method that a kind of sludge reduction that shortens the time obtains fly maggot protein simultaneously.
Technical scheme of the present invention is:
Handle active sludge and produce the method for fly maggot protein and mud base soil improvement agent, it is characterized in that: said method comprising the steps of:
(1) selects the fly maggot kind;
(2) active sludge is packed into inoculate fly maggot in the container,, under the envrionment conditions of ambient relative humidity 60% ~ 80%, cultivate after 3 ~ 10 days, separate fly maggot, the fly maggot oven dry is obtained dry product, dry product is pulverized made fly maggot protein then 20 ~ 35 ℃ of culture material temperature;
(3) will separate the solid matter that is left behind the fly maggot, in 15 ~ 35 ℃ of environment, sealing composting 3 ~ 10 days obtains mud base soil improvement agent.
Method according to the described processing active sludge of claim 1 is produced fly maggot protein and mud base soil improvement agent is characterized in that: the fly maggot kind is selected the two mixed population of a kind of or lucilia sericata larvae in lucilia sericata larvae, sarcophagid larva, the engineering fly maggot, sarcophagid larva for use.
According to the method that the described processing active sludge of claim 1 is produced fly maggot protein and mud base soil improvement agent, it is characterized in that: the water ratio of active sludge is 65% ~ 85%.
According to the method that the described processing active sludge of claim 1 is produced fly maggot protein and mud base soil improvement agent, it is characterized in that: container diameter is 500 ~ 1000mm, highly is 150 ~ 200mm.
According to the method for claim 1 or 4 described processing active sludge production fly maggot proteins and mud base soil improvement agent, it is characterized in that: the thickness of mud in container is 50 ~ 70mm.
The present invention compared with prior art has the following advantages:
1, because the present invention need not any middle-chain, directly with the active sludge after the fly maggot processing dehydration, therefore the nitrogen content of handling back mud base soil improvement agent is high by 10 ~ 20% 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 fly maggot to organic degradation characteristic, realizes innoxious, the stabilization and the resource utilization of mud, also can obtain high protein feed---fly maggot simultaneously, and the high-quality fertilizer is turned waste into wealth, and meets 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 excess sludge, every kilogram of active sludge can be gathered in the crops 0.20 ~ 0.40 kilogram of fly maggot, can get 0.03 ~ 0.12 kilogram of dry product, and processing costs is low, non-secondary pollution.
4, through the processing of the method for the invention, sludge volume has reduced 30% ~ 70%, has realized minimizing, stabilization, the innoxious and resource utilization of mud.
