【考案の詳細な説明】
(A) 産業上の利用分野
本考案は製造簡単な接触材に関し、特に活性汚
泥による汚水処理に好適な目詰まりしない耐久力
抜群な効率の高い接触材付きネツトに関する。[Detailed Description of the Invention] (A) Field of Industrial Application The present invention relates to a contact material that is easy to manufacture, and particularly to a net with a highly efficient contact material that does not clog and has excellent durability and is suitable for sewage treatment using activated sludge.
(B) 従来の技術
従来活性汚泥法汚水浄化にあつては汚泥と汚水
との相互接触を高める為ハニカム（蜂の巣型の積
層接触材）型の接触材を用いるのが常法であつ
た。(B) Conventional technology In conventional activated sludge method sewage purification, it has been common practice to use a honeycomb (honeycomb-shaped laminated contact material) type contact material to enhance mutual contact between sludge and wastewater.
然しながらハニカム接触材は効率は頗る高いが
穴径を細かく（径30−50mm位）とすると目詰まり
が激しい為これを交換して用いるのであるが、目
詰まりしたハニカムは汚泥が詰まつているので重
量が重いばかりでなくこれを廃棄処分するのが難
作業であつた、又ハニカム型接触材は薄い塩化ビ
ニールで作られる関係で耐用年数も短かゝつた。 However, although honeycomb contact material is highly efficient, if the hole diameter is made small (about 30-50 mm in diameter), clogging becomes severe, so it is replaced and used, but a clogged honeycomb is clogged with sludge. Not only was it heavy, but it was difficult to dispose of it, and since the honeycomb contact material was made of thin vinyl chloride, its useful life was short.
(C) 考案の解決しようとする問題点
以上のように慣用されているハニカム型接触材
の目詰まりが激しく且つ耐用年数が低く廃棄に手
間取る不便さを解決せんとするものである。(C) Problems to be solved by the invention As mentioned above, the invention aims to solve the inconvenience of the commonly used honeycomb type contact material, which is severely clogged, has a short service life, and takes time to dispose of.
(D) 目的
従つて本考案の目的はハニカム型の接触材の欠
点を改良し補つた、即ち目詰まりが無く交換の必
要の無い耐用年数が抜群に永い接触材付きネツト
を提供するにある。(D) Purpose Therefore, the purpose of the present invention is to improve and compensate for the drawbacks of the honeycomb type contact material, that is, to provide a net with a contact material that does not become clogged and does not require replacement and has an extremely long service life.
(E) 問題を解決する為の手段
目詰まりを防止する為本考案にあつてはパス
（通路）自由な縦に平行に付設されたネツトを枠
にて吊し且つネツトの交点の結び目に接触効果を
上げる為ポリエチレン等の合成樹脂テープを短冊
型に切つた接触材を係合せしめこの接触材に活性
汚泥層を生長せしめて高度の接触をせしめんとす
るものである。(E) Means to solve the problem In order to prevent clogging, in the present invention, nets attached vertically and parallel to each other with free paths are suspended from a frame, and the nets are brought into contact with the knots at the intersections of the nets. In order to increase the effect, a contact material made of a synthetic resin tape such as polyethylene cut into strips is engaged, and an activated sludge layer is grown on this contact material to achieve a high degree of contact.
(F) 作用
ネツトの結び目に設けられた接触材は縛られて
はいるが表面積が大で且つたわみ性を有する為自
由に汚水と接触して効果を上げ且つ浮動するので
目詰まりを起こす事が無い。(F) Effect Although the contact material attached to the knot of the net is tied, it has a large surface area and is flexible, so it can freely come into contact with wastewater to increase its effectiveness and float, so it does not cause clogging. None.
(G) 実施例
図面によつて本考案の実施例について説明す
る。(G) Examples Examples of the present invention will be explained with reference to drawings.
図において略正方形の網目に張られたネツト２
は枠１に張られて複数の平行なネツトの群を形成
する。 In the figure, net 2 is laid out in a roughly square mesh.
are stretched across frame 1 to form a group of parallel nets.
各ネツト２の結び目３にはポリエチレン等で作
られた耐久性のある合成樹脂製のテープを短冊型
に切つた接触材４（複数でも良い）が係合してい
て幅広のテープ状の接触材４は表面積が大で且つ
たわみ性の故に目詰まりが無い。 The knot 3 of each net 2 is engaged with a contact material 4 (or more than one) made of a durable synthetic resin tape made of polyethylene or the like cut into strips, and is a wide tape-shaped contact material. No. 4 has a large surface area and is flexible, so there is no clogging.
(H) 考案の効果
本考案の装置は構造簡単で多量生産に適し安価
で経済的ではあるがネツトの結び目につけられた
接触材により充分なる活性汚泥付着面積を保持
し、且つ浮動する事により過剰の汚泥や異物の付
着を防止し、目詰まりを完全に防止し耐用年数を
充分延ばす効果がある。(H) Effects of the invention The device of the invention has a simple structure, is suitable for mass production, and is inexpensive and economical. However, the contact material attached to the knot of the net maintains a sufficient activated sludge adhesion area, and the floating system prevents excess activated sludge. It has the effect of preventing the adhesion of sludge and foreign matter, completely preventing clogging, and sufficiently extending the service life.
