By adding a superabsorbent resin to liquid organic sludge with a high moisture content and containing organic matter, the sludge is adjusted to have an appropriate moisture content for the growth of earthworms.Next, earthworms are inoculated into this sludge to make the sludge By feeding and growing the organic matter in the sludge, earthworms multiply and biologically treat the organic matter in the sludge. A calcium chloride solution is added to release the water occluded by the superabsorbent resin, returning it to a low-viscosity liquid sludge.Next, this liquid sludge containing earthworms is passed through a sieve with holes of several millimeters in diameter. By sieving only the sludge and harvesting the earthworms that remain on the sieve, the costly process of making a dehydrated cake from liquid organic sludge is omitted, making it possible to harvest earthworms without much effort. , which aims to simplify and speed up the work of worm farming and reduce costs.

うにしたことを特徴とする。91 Means for Solving the Problems The method for cultivating earthworms of the present invention involves adding a superabsorbent resin to liquid organic sludge with a high moisture content that contains organic matter produced as a by-product in water treatment and waste treatment. By doing this, the sludge is adjusted to have an appropriate moisture content for the growth of earthworms, and then earthworms are planted in this sludge and grown by feeding on the organic matter in the sludge. Biological treatment of organic matter is carried out, and then a calcium chloride solution is added to the sludge that has been adjusted to lower the water content by adding a superabsorbent resin, and the water occluded by the superabsorbent resin is released. The liquid sludge containing the earthworms was returned to a low-viscosity liquid sludge, and then the liquid sludge containing earthworms was passed through a sieve with openings several millimeters in diameter, only the liquid sludge was sieved off, and the earthworms remaining on the sieve were harvested. It is characterized by
Ｆ１作用
上述したような手段によることにより、液状有機汚泥中
に添加された高吸水性樹脂が水分を吸収して膨潤し、こ
の汚泥をミミズの生育にとって適度な含水率に調整する
という作用を奏する。F1 Effect By using the above-mentioned means, the super absorbent resin added to the liquid organic sludge absorbs water and swells, thereby adjusting the water content of this sludge to an appropriate level for the growth of earthworms. .
また、ミミズを養殖した年度の高い高吸水性樹脂混入の

泥に改変せしめるという作用を奏する。In addition, by adding a calcium chloride solution to the sludge mixed with highly absorbent resin from the year in which the earthworms were cultivated, the super absorbent resin undergoes secondary crosslinking and shrinks, releasing a portion of the occluded water. This has the effect of modifying the liquid sludge into highly fluid liquid sludge.
Ｇ、実施例
以下本発明のミミズの養殖方法の一実施例を第１図に従
って説明する。G. Example Hereinafter, an example of the method for cultivating earthworms of the present invention will be described with reference to FIG.
第１図の工程図で、水処理、廃棄物処理工程６と、次の
液状汚泥取り出し工程７は、従来のミミズ養殖法と同様
である。In the process diagram of FIG. 1, the water treatment and waste treatment steps 6 and the next liquid sludge removal step 7 are the same as in the conventional earthworm farming method.
すなわち、水処理、廃棄物処理工程６で、生汚泥、活性
汚泥さらに消化汚泥、また畜ふん搾汁液。That is, in water treatment and waste treatment step 6, raw sludge, activated sludge, digested sludge, and livestock dung juice are extracted.
畜ふん搾汁液消化汚泥等の、有機物を含む流動性に富ん
だ液状有機汚泥が生成される。Fluid organic sludge containing organic matter, such as digested sludge from livestock excrement juice, is produced.
次に、液状有機汚泥は、液状汚泥取り出し工程７で、沈
澱、ろ過又は搾汁機等により分離集積される。Next, in a liquid sludge removal step 7, the liquid organic sludge is separated and accumulated by sedimentation, filtration, a squeezer, or the like.
次に、膨潤（水分吸蔵）工程８において、液状有機汚泥
に高吸水性樹脂（ポリアクリル酸系）粉末を適当量添加
し、撹拌する。この高吸水性樹脂は、自重の数１０倍以
上の水分を吸収して膨潤し、しかも、外から力を加えて
も吸蔵した水を放出しにくいものである。Next, in the swelling (moisture absorption) step 8, a suitable amount of super absorbent resin (polyacrylic acid type) powder is added to the liquid organic sludge and stirred. This super-absorbent resin swells by absorbing water several tens of times its own weight, and moreover, it is difficult to release the occluded water even when force is applied from the outside.
従って、液状有機汚泥中の水分がこの高吸水性樹脂に含
浸され、ミミズの生育にとって適度な含水率となり、通
気性と保温性が得られる土の如き状態となる。Therefore, the water in the liquid organic sludge is impregnated with this superabsorbent resin, resulting in an appropriate moisture content for the growth of earthworms, resulting in a soil-like condition that provides breathability and heat retention.
次にミミズ養殖工程９で、高吸水性樹脂を混入した汚泥
中に、ミミズを植種する。Next, in an earthworm cultivation step 9, earthworms are inoculated into the sludge mixed with super absorbent resin.
すると、ミミズは、膨潤した高吸水性樹脂の間にとり残
された汚泥をのみ込み、そのなかの有機物を摂取して排
出する。The earthworms then swallow the sludge left behind between the swollen superabsorbent resins, ingest the organic matter in it, and excrete it.
このようにしてミミズは、汚泥中の有機物を処理しなが
ら生育し、繁殖する。In this way, earthworms grow and reproduce while processing the organic matter in the sludge.
そして、ミミズが、汚泥中の有機物を食べ尽した頃に、
ミミズを収穫するための汚泥液状化工程１０に移行する
。When the earthworms have eaten up all the organic matter in the sludge,
The process moves to sludge liquefaction step 10 for harvesting earthworms.
この工程では、汚泥中に混入した高吸水性樹脂が膨潤し
た状態では、その粘性が高いために、これを掘り起こし
てミミズを採取するのが容易ではないので、塩化カルシ
ュラム（Ｃａｃｌ＊）溶液を添加し、高吸水性樹脂に２
次架橋を起こさせ収縮させて、吸蔵した水の一部を放出
させ、粘性の低い流動性の液状汚泥に戻すようにする。In this process, when the superabsorbent resin mixed in the sludge is swollen, its viscosity is high, so it is not easy to dig it up and collect the earthworms, so a calcium chloride (CaCl*) solution is added. and super absorbent resin 2
The sludge is then cross-linked and contracted to release some of the occluded water and return it to a fluid liquid sludge with low viscosity.
次に、ミミズ収穫工程１１において、このミミズを含ん
だ液状汚泥を、直径数ミリメートルの目をもつ篩にかけ
る。Next, in an earthworm harvesting step 11, the liquid sludge containing earthworms is passed through a sieve with openings of several millimeters in diameter.
すると、液状汚泥は、この篩を通過し、ミミズだけが篩
の上に残る。よって、この篩の上のミミズを容易に収穫
することができるものである。The liquid sludge then passes through this sieve, leaving only the earthworms on the sieve. Therefore, the earthworms above the sieve can be easily harvested.
