Embodiment Construction
[0007] In one embodiment of the present invention, the method of the present invention includes: a closed sewage pool, a solar sewage heater and a sewage circulating pump, an exhaust pipe is arranged on the upper part of the sewage pool leading to high altitude, and there is a valve control on the exhaust pipe; During operation, use the sewage circulation pump to send the sewage at the bottom of the sewage pool to the solar sewage heater, and then return to the top of the sewage pool after heating. After continuous circulation of sewage, the temperature will gradually rise until it reaches ≥70 ° C and maintains for one hour above.

The low heat waste water sterilizing method is that waste water is led into container and heated to not lower than 70 deg.c for over 1 hr to kill microbe, virus, germ and parasite egg completely to reach the aim of sterilizing waste water. The said method is named as pasteurization. The heat source for heating waste water may be solar energy, heat the waste water produces during fermentation or heat produced in burning fuel.
Description
technical field [0001] The invention belongs to the technical field of sewage treatment and is suitable for disinfection treatment of domestic sewage, hospital sewage and other sewage. Background technique [0002] As we all know, sewage is produced with the progress of human civilization, and with the improvement of people's living standards, its output is also increasing rapidly; domestic sewage, hospital sewage and other sewage not only contain a large number of pollutants, but also contain pathogenic microorganisms, Germs, viruses, and parasite eggs, if not disinfected, will spread diseases and seriously endanger the health and safety of humans and animals. From another point of view, the pollutants in domestic sewage are mainly organic matter and inorganic salts, which are rich in nitrogen, phosphorus, potassium, calcium, magnesium, sulfur and other elements needed for plant growth. Organic matter can improve soil and directly Absorbed and utilized by plants; the curre...
