Description

  The present invention relates to the prevention of air pollution and environmental pollution of river water areas directly or indirectly generated by a septic tank, and in particular, as a septic tank that does not hinder the maintenance of the living environment and health and hygiene, A wastewater purification device that solves the problem of preventing exhaustion of carbon dioxide and preventing the increase in carbon dioxide, reclaims sewage in the water area as water that can be used as fish, and can be reused as water for plant irrigation and flushing in flush toilets. It is concerned.

  Reinforced concrete septic tanks built on-site in accordance with the technology based on the structural standards based on the existing Building Standards Law are currently priced lower than FRP septic tanks commercialized as factory products. Due to the speed of cheap construction, etc., it is impossible to compete commercially, and the contractor is noticeably out of business. Although the FRP septic tank is monopolized in the national market, however, the FRP septic tank is a chemical product, and the equipment and structure are completely different from the present invention. Rehabilitation and reconstruction of a steel septic tank supplier is desired.

  Conventionally, as environmental pollution that occurs in the manufacturing process of factory-produced FRP septic tanks, in addition to the harmful effects of using thinner coagulant, dust pollution such as plastics generated during polishing and cutting of materials In addition, harmful deoxins are released during the depreciation of debris and pollute the atmosphere. Also, in terms of purifying power, there is no measure for removing sewage containing detergent, agricultural chemicals and food additives discharged from the body, and a large amount of flocculant and chlorine sterilant are used to reduce released BOD. For this reason, the ecology of river water is crazy, and seafood and algae are dead. There are issues that must be resolved.

  In conventional FRP septic tanks, the biofilm contact aeration type is the mainstream, and there are various contact materials such as honeycombs of chemical products, and it is a means to attach filamentous fungi that are biofilms. There are no examples of biofilm adhering to products, and the conventional aeration apparatus is used for activated sludge system that decomposes and purifies with fluid microorganisms. This is a problem because it obstructs the flow, becomes anaerobic, generates a foul odor, and impairs the maintenance of the living environment due to the consumption of oxygen.

  In the conventional FRP-type septic tank sales and construction, as a biofilm separation contact type, the same model is sold and constructed regardless of whether it is a general facility, restaurant, hotel, or food factory. There is a problem that it must be sorted for facilities, and sludge carried out during cleaning and the amount of sludge reduced.

Means to solve the problem

  Air pollution, which was listed as an adverse effect of FRP septic tanks in Problem [03, 04], can be solved by using concrete septic tanks. Due to poor ecology of existing FRP septic tanks, flocculants and chlorine sterilants The damage to the seafood and algae in the river water area that occurs is solved by the tertiary treatment purification device equipped with the watering septic tank of claim 3 and the magnetic sterilization device.

  Regarding the problem [04], the disadvantages such as the aeration apparatus in the conventional biofilm type FRP septic tank, the contact material such as the honeycomb of the chemical product, and the biological treatment of the biofilm are solved by the three-phase aeration apparatus, At the same time, the sewage is treated by changing the sewage from anaerobic to aerobic, neutralizing the acidity to mineralize the pollutant, producing a plant chain from microbacteria to metazoans.

  Regarding subject [05], the oxidation type reduction according to claim 4 having a daily inflow BOD concentration of 200 PPM or less and a daily inflow sewage amount of 40 Lippo meter or less depending on the use of the biofilm contact aeration type This system will be used for general facilities. Further, the daily inflow BOD concentration of 200 PPM or more and the daily inflow sewage amount of 40 Lippo meter or more are defined as the reduction-type sewage purification apparatus according to claim 5, and this is the purification apparatus for specific facilities.
