ている。Large amounts of organic or inorganic undissolved substances contained in civil engineering wastewater, sewage water, or industrial wastewater become floating substances in water and are disposed of in rivers or the sea, causing pollution. Therefore, recently, the above-mentioned civil engineering waste liquid and the like are treated to reduce the concentration of suspended matter in the water to below a standard level before being disposed of, but the time and expense required for this treatment are enormous.

ある。For example, titanium oxide, a pigment used in paper mills to smooth the surface of paper, takes a very long time to recover, resulting in increased product costs. Furthermore, since the water from rivers and lakes used as water sources contains a large amount of the above-mentioned undissolved substances, it is supplied as tap water after being treated at a great deal of time and expense. Furthermore, there is an ever-increasing demand for measures to deal with floating matter in ponds, which occur during seabed dredging, and to deal with red tide in oceans and lakes.

In this case, suspended matter in the water is once aggregated and sent to a centrifuge,
After being dehydrated, if necessary, it is solidified and disposed of. Also, if it contains organic matter, it will cause a pollution problem if it is disposed of unnecessarily, so it is first incinerated and the incinerated ash is disposed of. In some cases.

用されている。Various flocculants have been developed for use in the flocculation process. For example, inorganic systems include aluminum salts (aluminum sulfate, ammonium alum, potassium alum, sodium aluminate, polyaluminum chloride), iron salts (ferrous chloride, ferric chloride, ferrous sulfate, ferric sulfate, polysulfuric acid). For organic systems (ferric iron, etc.), low-molecular salts, surfactants, natural or synthetic polymers, etc. have been developed and used.

沈澱物がべとついた惑しとなり遠心分離機等によっても
フロックからの水分の分離がし難いという難点がある。Inorganic flocculants generally have excellent adsorption and collection power, so
Although the supernatant liquid after use has good transparency and water can be easily separated from the precipitate, it has a slow aggregation rate and is generally an acidic substance, so an alkaline neutralizing agent such as slaked lime or soda is required after treatment. It was necessary to neutralize the water by adding ash and caustic soda. Organic flocculants are generally expensive, and furthermore, the flocs (each particle of the precipitate formed when a flocculant is mixed) are lower than when an inorganic flocculant is used. Although it is larger, it has inferior adsorption and collection power, leaving the supernatant turbid, and other problems.
The problem is that the precipitate becomes sticky and sticky, making it difficult to separate water from the floc using a centrifuge or the like.
そこで、必要な場合には有機系の凝集剤に無機系の凝集
剤を混入して使用しているのが現状である。Therefore, at present, when necessary, an inorganic flocculant is mixed with an organic flocculant.

った問題点があった。In addition, the above-mentioned flocculants are not versatile, and the type of flocculant used is limited depending on the properties of the liquid to be treated.
Further, the amount to be added is determined depending on the properties of the agent to be treated, and there is a problem in that if the amount is outside of that amount, there is no aggregation effect.

て少なくする（又はアルミニウム塩の量を多くする）。The blending ratio of each of the above substances can be considered based on the following criteria. The liquid to be treated is neutral and contains a reaction moderator (
When a neutral substance such as gypsum, rhusium carbonate, fly ash, or mirabilite is used as a sequestering agent, the ratio of soluble aluminum salt (iron salt) to alkali metal carbonate is stoichiometrically neutral. The proportion becomes . For example, aluminum sulfate (purity 58.7) is used as a soluble aluminum salt.
If sodium carbonate is used as the alkali metal carbonate, it may be blended in an amount (weight ratio) of approximately 5 parts aluminum sulfate to 3 parts sodium carbonate or 3 parts aluminum sulfate to 2 parts aluminum carbonate. However, even if the ratio slightly deviates from this ratio, the object of the present invention can be sufficiently achieved. When cement is used as the calcium compound, reduce the amount of alkali metal carbonate (or increase the amount of aluminum salt) according to the amount of cement.

いは少なくとも何れか一方が投入された直後である。In this invention, it is believed that the alkali metal carbonate promotes the decomposition of soluble aluminum salts (iron salts) and enhances its effectiveness as a flocculant, dehydrating agent, desalting agent, and decoloring agent. Therefore, in this invention, the soluble aluminum salt (iron salt) and the alkali metal carbonate are added almost simultaneously (this also includes the case where the next drug is injected while the activity of the previously injected drug remains). It is meaningful only when it is added to the liquid to be treated. For example, if a soluble aluminum salt is mixed into the treated agent first, and then an alkali metal carbonate is added after its activity has disappeared, the alkali metal carbonate will still function as a conventional neutralizing agent, but will still coagulate. No promoting effect appears. When a reaction moderator such as a calcium compound is used, the calcium compound is added immediately before the aluminum salt (iron salt) and the alkali metal carbonate, or immediately after at least one of them is added.

水処理剤に対して９０重量％まで加えることが出来る。In the present invention, not only inorganic raw materials are used as described above, but also an organic water treatment agent (flocculant) can be mixed in addition to the above-mentioned inorganic raw materials. Organic water treatment agents include anionic, cationic, nonionic, etc., and at least one of each is used depending on the properties of the liquid to be treated. The amount of this organic water treatment agent added varies depending on the liquid to be treated, but it is necessary to add 0.1% by weight or more to the inorganic water treatment agent of the present invention. As the amount of organic water treatment agent added increases, the defects of conventional organic water treatment agents become more obvious, and the upper limit varies depending on the nature of the liquid to be treated. It can be added up to 90% by weight.

Both mud diluted liquid and titanium oxide diluted liquid are 1100pp.
The concentration of the treated liquid was 120 g, and the mixed water treatment agent was 0.08% by weight. For comparison, a flocculation test was conducted using only aluminum sulfate, but it took about 24 hours for the mud to settle and the transparency of the supernatant was not sufficient.

As is clear from this table, it is sufficient that the addition rate is 0.1% by weight or less of the liquid to be treated, and it can be seen that the larger the addition amount, the faster the aggregation rate. Further, as shown in Table 4, the aggregation rate of agent B is faster than agent M, but this is thought to be due to the difference in the fly ash content of agent B. That is, it is considered that the crosslinking effect of fly ash is at work.

果がある。Bentonite particles in Table 1 are difficult to settle, and if they are precipitated using only a polymeric a collector, the sedimentation rate is high, but the supernatant does not have sufficient clarity. However, the above table [Tables 7 to 9]
As is clear from the table, the use of the water treatment agent according to the present invention has a remarkable effect on sedimentation. Examining Table 7, it can be seen that with agent B alone, the compactness of the sedimentation is slightly inferior, but the remaining amount of suspended matter is very small, and a clear supernatant liquid can be obtained. In addition, the flocculation method in which a polymer flocculant is added after addition of agent B has a considerable effect as far as Table 8 is considered, but as can be seen from Table 9, the inorganic water treatment agent of the present invention It is also effective to add a predetermined amount of a polymer flocculant in advance.

水剤にある。また有機高分子の脱水剤は価格が高い点で
も不利益である。As a dewatering system for sewage sludge, a belt press dewatering system using an organic polymer dehydrating agent has become popular.
The amount of sludge with poor dewatering properties is increasing, and the peelability of the dewatered cake from the filter cloth is worsening, which is a problem in terms of maintenance and management of the dehydrator. One of the reasons for this is the dehydrating agent for organic polymers. Organic polymer dehydrating agents are also disadvantageous in that they are expensive.
そこで、本願発明を用いて、有機高分子の脱水剤の利点

。As is clear from Table 12, when the dehydrating agent of the present invention is used, the amount of gravity filtration in 5 seconds becomes incomparably larger, and the effect is particularly remarkable when the amount of agent B added is 3% to 5%, and the dehydrating property is improved. It proves that In addition, the releasability (the cake peels off from the upper and lower cloths after pressure filtration) is also improved, but in this case as well, the effect begins to be seen when the amount of agent B added is 3% or more, but when the amount of agent B is 5% or more, The effect becomes more pronounced.
更に加圧脱水後のケーキ水分も１％程度小さくなってお
り、この点からも脱水性の向上が期待できる。Furthermore, the moisture content of the cake after pressure dehydration was reduced by about 1%, and from this point as well, improvement in dehydration performance can be expected.

能である。As mentioned above, this invention uses soluble aluminum salt (iron salt) and alkali metal carbonate as its main ingredients, and if necessary, adds a calcium compound or the like to rapidly bring out the coagulation effect of aluminum sulfate. This has the effect of greatly increasing the aggregation rate. In addition, the amount added is not limited by the type or concentration of the liquid to be treated, and a large aggregation effect occurs, and the aggregation rate increases according to the amount added, so the work to determine the amount to be added is extremely easy. . Furthermore, if the formulation is determined according to the pH state of the liquid to be treated, no neutralizing agent is required at all. In addition, since the aggregation speed is high, it is possible to save space in equipment and equipment. Furthermore, in addition to the above-mentioned aggregation effect, when used as a dehydrating agent, it also exhibits a dehydrating effect. Furthermore, it has a desalting effect and a decolorizing effect, and can be applied to all types of water treatment.
