Hydroponics of vegetables:
Wastewater (sewage and miscellaneous wastewater) from agricultural settlements was supplied to the reclaimed water production facility. In the reclaimed water production facility, reclaimed water is produced by the action of useful microorganisms cultured in a useful microorganism culture tank. The produced reclaimed water has a bactericidal action due to the action of useful microorganisms, and as shown in FIG. 9, almost no harmful E. coli and general bacteria are eliminated. can do. The produced reclaimed water was appropriately supplied to a hydroponics pond in a greenhouse made of a transparent material to grow vegetables and the like. In the indoor plant cultivation facility, sunlight was used in the daytime, and when the nighttime sunlight was insufficient, the illuminance in the house was automatically detected by a sensor, and the necessary illuminance was ensured by artificial lighting such as a light emitting diode (LED). It is necessary to drain the reclaimed water that has been thrown in, and the surplus drainage was returned to the reclaimed water production facility by a pump and recycled.

  The effect of the reclaimed water was as follows as a result of using the reclaimed water produced at the farm village drainage treatment facility in the formerly suitable area of Saga City for the vegetable cultivation at the farm. In the house cultivation of Saga's “Sagahonoka”, the sugar content is usually 12-14 degrees, and even on average 13 degrees is considered sweet enough, but when using this reclaimed water, the sugar content averages 15-16 degrees It has good color and good quality cocoons, and the rate of commercialization has improved. Conventionally, agricultural chemicals cannot be separated for cultivation, but the use of the reclaimed water eliminates the need for soil disinfection. Similarly, it has been reported that farmers who grow cherry tomatoes use the reclaimed water to produce no disease at all without pesticides, greatly increase the yield, and increase the sugar content. Moreover, in the cabbage growing farm, the use of the reclaimed water promotes soil agglomeration, improves water retention capacity, improves fermentative decomposition capacity such as organic compost, and the size of cabbage as shown in FIG. It has been reported that (height) has grown twice as much as before, has become high quality, and the yield has increased significantly. Furthermore, regarding the deodorizing effect of odors, as shown in FIG. 11, the odor index in the conventional treatment plant was 40 to 25, as is clear from the odor concentration and odor index data of the agricultural settlement drainage treatment facility in the original district. However, the effect is clear. In house cultivation, the odor peculiar to the house that had been generated has decreased.

Suppon aquaculture:
Here, the same reclaimed water as used in Example 1 was used. In the present invention, 2 to 4 concrete ponds are installed in a house made of transparent roofing material such as airtight glass, vinyl, polycarbonate, etc., and young turtles divided according to their growth stages are placed therein. And reared. Each tank was charged with 10 to 20 l (liter) of reclaimed water produced in a reclaimed water production facility for 1 m ^{3 of} water tank per month. As a result, after about one month, the water in the aquarium was brown and cloudy, but the transparency increased and it turned red. This is the result of the propagation of photosynthetic bacteria (red bacteria) in the tank, which greatly eliminated the odor in the house and greatly improved the house environment. In addition, disinfectants that had previously been put into the tank to prevent spoilage are no longer necessary after the addition of recycled water, and the cost of antibiotics has been reduced by 800,000 yen per month. In addition, the pupons were not killed, the growth rate was faster than before, and the shipping production was quadrupled. Suppon's quality as a food ingredient improves the color of the suppon and eliminates the odor of meat that used to be. As a result, safety is ensured without using antibiotics, etc. so that it can be shipped as a luxury product. became. Wastewater from the tank and low quality (sludge) were returned to the wastewater treatment facility by a pump, treated by useful microorganisms, and recycled.

This example incorporates a sludge reformer (bioreactor) into a wastewater treatment facility in Gunma Prefecture to cultivate useful microorganisms and to make the best use of microorganisms in anaerobic and aerobic tanks. A monitoring and control device was installed. The treated raw water is a daily drainage from an agricultural village, and is at a certain level per day as shown in the inflow water amount data in FIG. The amount of water will give a warning at a certain level, and if it reaches a certain level, it will give a warning and take the measures to the site. For daily water quality management, the oxidation-reduction potentiometer (ORP meter) of the aeration tank is the main management item. As shown in Fig. 3, the aerobic side issues a warning at a certain level, and further alerts at a certain level. Set to emit. With this, when a warning is issued, the aerating time timer setting interval can be remotely adjusted and adjusted, and when the alarm line is reached, the aerating air volume can be adjusted by going to the site, It is possible to take measures by adjusting the amount of returned sludge. Similarly, the anaerobic side can be managed. At the same time, the oxygen concentration meter (DO meter) is also measured, and the operation management data is accumulated by checking the correlation with the oxidation-reduction potential (ORP) to improve the operation management method suitable for each treatment plant. I can do it. By adopting this remote monitoring and control method, it is possible to manage the operation of a skilled person from a remote location with a small number of people, making it possible to greatly save the operation management and ensure appropriate processing performance.
