本発明は、汚濁水の処理方法に関し、さらに詳しくは汚
濁水の１縦に対応した量の薬注を行う処理方法である。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for treating polluted water, and more specifically to a method for dispensing a chemical in an amount corresponding to one length of polluted water.

結果汚＋１＃粒子をさらに分散させることになる。Conventionally, when clarifying polluted water, various chemicals are added to make the pollutant particles in the polluted water floc, which are then allowed to settle out for clarification172. Small method A method has been adopted in which an aqueous solution containing a chemical (flocculant) dissolved in Nemotsubara polluted water is added in a stationary manner. It is normal for the concentration of polluted water to constantly fluctuate despite the LmL. If chemicals are quantitatively poured into this polluted water, if the concentration of the polluted water is high, #i drain injection will be insufficient and sufficient flocculation of pollutant particles will not be achieved, and on the contrary, the concentration of the polluted water will be low. In this case, the result is that too much straw is placed, which results in further dispersion of dirt +1# particles.
本発明者はこれら従来の欠点を解決すべく種々研究を重
ねた結果本発明を完成するに至った。The present inventor has completed the present invention as a result of repeated research in order to solve these conventional drawbacks.
すなわち本発明は汚濁水を管体内に一定圧力で流した場
合汚、濁水の農産により管体内の流速が変化することに
増目して本発明を完成した迭のである。That is, the present invention was completed by focusing on the fact that when polluted water is allowed to flow inside a pipe at a constant pressure, the flow velocity inside the pipe changes depending on the agricultural production of the dirt and turbid water.

力に相応する信号を送や、かかる信号によって薬注装置
を制御して予め汚濁水濃度に適合した量の薬注を行う。First, polluted water is caused to flow into a pipe having a constant diameter according to the present invention under a substantially constant pressure, and the degree of m and the flow rate of the polluted water at that time are investigated in advance. Then, the amount of medicine to be injected that matches the concentration of the polluted water is stored in advance in, for example, a computer. and tube body Kti
A flow rate measuring device is provided to measure the flow rate of contaminated water flowing through the pipe body.The signal measured by this flow rate measuring device is inputted into a converter, and the converter sends a signal corresponding to the human power to the computer. The chemical injection device is controlled by such a signal, and the chemical injection is performed in advance in an amount that matches the concentration of the polluted water.
このように構成する仁とによって汚濁水製ｆが変化して

汚濁粒そのフロック化の環境を作ることができ効率的に
汚濁水の処理をすることがてきる。With this structure, even if the filtrate of the polluted water changes, it is possible to perform chemical dosing that is compatible with the change, creating an ideal environment for the flocculation of polluted grains and efficiently treating the polluted water. I can do that.
