る。 Conventionally, equipment that continuously processes wastewater until it produces sludge includes coagulation sedimentation equipment, pressure flotation equipment,
Some systems, such as activated sludge treatment equipment, are installed in a series to treat sludge in sequence, but because it uses biological treatment, the reaction speed is slow and the treatment efficiency is low, so it takes a long time to complete the treatment. Therefore, the device is inevitably large in size, requires extensive civil engineering work, and requires a vast area of land for installation, resulting in an enormous equipment cost. Therefore, it is extremely difficult to install a system unless you have a considerable amount of financial leeway, and the reality is that small and medium-sized businesses, in particular, struggle to implement countermeasures because they lack funds. The present invention improves on these drawbacks, and the concentrated sludge is compact and requires almost no civil engineering work, and can be easily separated from wastewater using only slope materials. In addition to extracting it as sludge, the wastewater is quickly filtered by gravity using a slope member that is driven intermittently without causing the flocs in the wastewater to settle. The purified water is then discharged to the outside, and the concentrated sludge and purified water are separated while detecting the water level. The purpose of the present invention is to provide a simple wastewater treatment device with a small installation area, which has a compact structure that organically arranges efficient devices that can perform wastewater treatment in a short time and continuously using simple means. It is something.

さらに大きなフロツクに成長せしめる。 Next, it is sent to the reaction tank 2 through the pipe L1 by the pump P1 . On the other hand, when a pre-dissolved acidic inorganic chemical such as aluminum sulfate is injected into the dissolution tank 3 and stirred with the agitator A1 , the substances contained in the wastewater become complex ions of metal hydroxides, which are converted into BOD.
Microscopic flocs are formed in which subcolloids and colloids, which are the elements of colloids, are adsorbed. Furthermore, when a pre-dissolved basic inorganic chemical such as sodium hydroxide is poured into the dissolving tank 4 and stirred, it becomes a water-insoluble metal hydroxide at a fast reaction rate and grows into a large floc. The treated water is further introduced into the flocculating tank 16, and a pre-dissolved organic chemical such as a polymer flocculant is injected thereinto, and the flocs are stirred by an agitator A5 to grow into larger flocs.

に返送される。 Next, this wastewater containing large flocs is continuously poured into the skimming chamber 6 of the superconcentrator 5 . This wastewater is passed through the inclined flocking material 9 by gravity. The flocking material 9 is stopped while there is little clogging, but as the clogging progresses and more sludge adheres, the water level rises, the float switch 11 is activated, the flocking material advances, and the attached sludge is transferred to the whipper 12. When he reached the place, he was knocked down. When the clean part of the flocked material appears on the upper running section, the water level will drop and the flocked material will stop. This action is repeated.
The purified water passed through the flocking material 9 by gravity is discharged to the outside from the purified water receiving portion 13a. Further, the water containing some SS is returned to the storage tank 1 from the portion 13b which receives superfluous water containing some SS.
The knocked-off sludge slides down the chute S 1 and enters the stirring mixing tank 13, where an organic chemical such as a polymer flocculant is added from the organic chemical dissolving tank 15, and when stirred by the rotary blades 14, the lumpy sludge is divided into small pieces. , it becomes granular and easily dehydrated. This granular sludge slides down the chute S 2 and goes to the endless water absorbent belt 21 of the dehydrator 17 .
The water falls to the top and is sent to the cylinder 18, where it is dehydrated by the pressure of the press roll 19 and the pressing force of the water-absorbing belt, becoming sludge with a water content of 85% or more, which is scraped off with the scraping knife 22, and the sludge is removed. It falls into the receiving box 23 and is discarded. Excess water is in storage tank 1
will be returned to.

利点がある。 As described above, the simple wastewater treatment device of the present invention is a compact and efficient device in which efficient small devices are organically arranged, and in particular, it can be operated intermittently by controlling the upper limit water level in one tank. By simply using an endless material to hold the flocs, the flocs can be easily taken out as thickened sludge to the next device without using any other device to hold the flocs.Moreover, the flocs in the wastewater can be tilted without settling to the bottom of the tank. Purified water can be obtained in a short time by simply gravity-filtering the wastewater in the tank using the endless material, and this purified water can be discharged to the outside. The water level rises, the endless material moves in response to the detection signal, the thickened sludge is transported, and at the same time a new overflow surface appears, active gravity overflow starts again, and the water level in the tank decreases.This process is repeated, making it compact. It has the unique effect of being able to efficiently separate concentrated sludge and purified water in a short period of time using standard equipment, and also allowing continuous wastewater treatment. Also,
The above-mentioned thickened sludge can be further taken out as a sludge cake with a low water content by a dehydrator having the above-mentioned structure. Therefore, wastewater is treated continuously, efficiently, and quickly to obtain sludge with extremely low water content, making it easy to dispose of.In addition, the SS content and BOD value of the effluent after treatment are extremely low, improving water quality. It has many advantages, such as improved performance, compactness, low cost, easy installation, and small installation area.

7.0 SS=500~800ppm BOD=500~10000ppm. For chemical injection, aluminum sulfate and sodium hydroxide were added as inorganic chemicals, and polyacrylamide was added as an organic chemical. The water content of the sludge after treatment was 78% and was used as fertilizer. Overwater has a pH of 6.8
SS = 80ppm BOD = 70ppm and was discharged without any problems.

水処理装置。1. A storage tank that equalizes the quality of inflowing wastewater;
A reaction tank that adds inorganic chemicals to the wastewater introduced from the storage tank and mixes and stirs them to form micro flocs, a flocculation tank that adds organic chemicals to the wastewater introduced from the reaction tank, mixes them, and forms large flocs, and an upper limit water level. An endless member that is activated intermittently in response to a detection signal is placed at an angle in the tank, and wastewater introduced into the tank from the flocculation tank is passed through the endless member by gravity, and purified water is discharged to the outside. a superconcentration device equipped with a skimming chamber for carrying out the process, and a sludge removal chamber for discharging the thickened sludge separated and conveyed by the endless material to the next device, and adding organic chemicals to the thickened sludge obtained from the superconcentration device. The sludge is characterized by being equipped with an agitation mixing tank that mixes and agitates the sludge to form granular sludge, and a dehydrator that dewaters the granular sludge with an endless water-absorbing belt that runs under pressure along a part of the circumference of the cylinder. A simple wastewater treatment device.
