Smart eco-friendly toilet pollution-discharge-free recycling automatic treatment system

Abstract

A smart eco-friendly toilet pollution-discharge-free recycling automatic treatment system includes: a smart eco-friendly toilet, a vacuum pollution discharge system, a first ejector, a first collecting box, a second collecting box, a second ejector, a solid-liquid separator, a drying system, a first buffer tank, a first self-priming pump, a precipitation buffer tank, an electrolytic apparatus, a membrane tank, an ozone generator, a high water tank and a control apparatus. The system can automatically operate without operators. The whole treating process is a physical treating process, no chemical agent is required, the treated dry power can be taken as a fertilizer, and the treated water can be taken as toilet water. The system can be used for various places, and laying of drainage pipes is not needed, so that investment to the toilet is reduced.

Description

technical field [0001] The invention relates to the technical field of feces harmless treatment, in particular to an automatic treatment system for non-sewage discharge and recycling of intelligent environment-friendly toilets. Background technique [0002] The increase and high concentration of the population make the output of urban manure continuously increase. In the past, most of these manures were directly transported to the countryside as fertilizers. However, under the impact of chemical fertilizers that can bring significant economic benefits, the use of manure in rural areas is shrinking day by day. Therefore, it is of great significance not only to protect the environment, but also to ensure the health of the people to manage and dispose of feces with appropriate technology. [0003] Fecal wastewater mainly has the characteristics of high suspended solids (SS), high concentration of ammonia nitrogen (NH3-N), high concentration of organic matter (COD), poor sensory...

AI Technical Summary

Problems solved by technology

The feces treatment method of the above mode has the following shortcomings: for the reception of high-concentration organic fecal sewage, the design capacity and working conditions of the sewage treatment plant are required to meet the standards for receiving sewage, and the fecal sewage is randomly discharged into the sewage pipe network It will bring great inconvenience to the construction planning of the sewage treatment plant; the fecal sewage will emit a strong odor on the way to the sewage treatment plant and it is difficult to treat the odor, which is not conducive to environmental sanitation

This type of treatment method has the following disadvantages: the waste liquid is directly discharged after the accumulation and chelation treatment, facultative treatment and primary / secondary aerobic treatment reach the standard. It is decomposed into organic matter that cannot be used as nutrients, and the organic matter in the feces cannot be fully recycled, and the nitriding treatment is not complete, and the COD removal efficiency is low; the dehydration treatment of sludge and feces is carried out through the same centrifuge, which is not convenient for feces. Reasonable utilization of nutrients in manure, because the dry sludge obtained from manure dehydration has high nutrients and can be used as fertilizer, while the dry sludge obtained from sludge dehydration has almost no nutrients, so it is not suitable to be used as fertilizer

However, the disadvantage of this patent is that the operation of the entire system needs to be controlled by the operator, and some chemical reagents need to be put in. Once the chemical reagents are put in too much, it will bring trouble to the subsequent treatment.
