Abstract

The invention provides a method for breeding earthworms treating urban domestic sludge. The method comprises the following steps: mixing different varieties of earthworms from different regions and feeding in a hybrid manner; selecting the big and strong earthworms, and circularly breeding for 3-8 cycles; feeding the bred earthworms with a sludge material for adaptability, and adding vitamins, oryzanol and EM to the sludge material; and continuously feeding the earthworms to increase the population quantity of earthworms. The earthworms bred by the method provided by the invention has great appetite, and remarkably increases the sludge treatment speed, wherein compared with the common earthworms, the sludge treatment efficiency is improved by about 5 times; and thus, the technology of treating sludge with earthworms is more practical and can be conveniently applied to production in a large scale.

Description

A kind of breeding method of handling the earthworm of municipal sludge

Technical field

The present invention relates to earthworm and cultivate technical field, a kind of specifically breeding method of handling the earthworm of municipal sludge.

Background technology

Along with industrialized development, the mankind are increasingly sharpened to water resource destruction and pollution, as industrial sewage, sanitary sewage etc.At present, in order to administer and to purify waste water, to reduce quantity of wastewater effluent, a large amount of municipal sewage plants has all been built in countries in the world, and still, sewage treatment plant is in carrying out sewage disposal process, the a large amount of mud of meeting output, because it is mud contains a large amount of pollutants and heavy metal, extremely difficult.Adopt known treatment technology, as landfill, burning, mummification conversion process, compost etc., not only the cost height needs to build a large amount of production facilities, and is easy to environment is produced secondary pollution.

In recent years, the technology of using earthworm to handle mud progressively is applied to produce, by the enzyme system (as protease, lipase, cellulase etc.) that earthworm self is abundant organic pollutant in the mud is decomposed, transforms, realize low cost, the harmless processing of mud, but use common earthworm, limited because of the appetite of common earthworm, its efficient of handling mud is lower, causes this kind technology can't in large-scale, high-efficiencyly be applied to produce.

Summary of the invention

At above the deficiencies in the prior art and defective, the object of the present invention is to provide a kind of breeding method of handling the earthworm of municipal sludge.

The objective of the invention is by realizing by the following technical solutions:

A kind of breeding method of handling the earthworm of municipal sludge may further comprise the steps:

With the local earthworm of zones of different different cultivars, nonlocal earthworm, import earthworm, put into breeding feed in the ratio of 1:1:1 and carry out the bulk crossing raising;

Choose earthworm big, that body is strong according to the bodily form of earthworm, and 3～8 cycles of circulation seed selection;

With the mud material earthworm of seed selection is carried out adaptability and raise, and in the mud material, add vitamin, oryzanol, EM(Effective Microorganism, beneficial microbe group);

Continue to feed earthworm, increase the population quantity of earthworm, be ready for use on production.

As the preferred technical solution of the present invention, the time that described bulk crossing is raised is 30～50 days.

As the preferred technical solution of the present invention, described breeding feed is the wherein a kind of of cow dung, pig manure, mud, mushroom residue or several mixture.

As the preferred technical solution of the present invention, describedly choose earthworm, its percentage of at every turn choosing is 40%～60%.

Compared with prior art, the earthworm appetite that the present invention cultivates is very big, and the speed of handling mud improves greatly, compare with common earthworm, its efficient of handling mud has improved about 5 times, makes earthworm handle the mud technology and has more practicality, is convenient to be applied on a large scale produce.

Embodiment

With the local earthworm of zones of different different cultivars, nonlocal earthworm, import earthworm (as from No. two, the peace of Japanese import), put into breeding feed in the ratio of 1:1:1 and carry out bulk crossing and raised 30～50 days, breeding feed can adopt the wherein a kind of of cow dung, pig manure, mud, mushroom residue or several mixture.

Then, choose earthworm big, that body is strong, active according to the bodily form of earthworm, 3～8 cycles of circulation seed selection, choose earthworm at every turn, its percentage of choosing is 40%～60%.

With the mud material earthworm of seed selection is carried out adaptability and raises, and in the mud material, add vitamin, oryzanol, EM(Effective Microorganism, beneficial microbe group), increase the appetite of earthworm.

Continue to feed earthworm, increase the population quantity of earthworm, be ready for use on production.For example, 10000 of each required earthworms of Treatment of Sludge, treat that the earthworm breeding is increased to this quantity after, just earthworm can be taken out, be applied to production.

The above is preferred embodiment of the present invention only, is not to be used for limiting practical range of the present invention; Every according to equivalence variation and modification that the present invention did, all covered by the scope of claims of the present invention.

Claims

1. a breeding method of handling the earthworm of municipal sludge is characterized in that, may further comprise the steps:

With the mud material earthworm of seed selection is carried out adaptability and raise, and in the mud material, add vitamin, oryzanol, EM;
