Abstract
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
The invention belongs to technical field of sewage, be applicable to disinfecting of sewage such as sanitary sewage, hospital sewage.
Background technology
As everyone knows, sewage is followed the human civilization progress and is produced, and along with the raising of living standards of the people, its output is also increasing rapidly; Except containing a large amount of pollutents, also contain pathogenic microorganism, germ, virus, parasitic ovum in the sewage such as sanitary sewage, hospital sewage, if not disinfection will be disseminated disease, the serious harm human and animal's is healthy and safe.From another angle, the pollutent in the sanitary sewage is mainly organism, inorganic salt, wherein contains the required elements of plant-growth such as abundant nitrogen, phosphorus, potassium, calcium, magnesium, sulphur, and organism can be improved the soil, and also can directly be utilized by plant absorbing; Present case is, people drop into substantial contribution and are used for sewage disposal on the one hand, and people use a large amount of fresh waters and fertilizer to be used for the maintenance of trees and flowers and plants again on the other hand; Fact proved, with undressed sanitary sewage pouring trees, flowers and plants, extraordinary effect is arranged, can save a large amount of fertilizer, saved simultaneously precious water resource again, also saved the sewage disposal expense, especially, done great economy and social effect like this in water resources today in short supply day by day.
Yet it is dangerous that the sewage of non-sterile is used to irrigate, and can disseminate disease.So the sterilization of sewage just becomes great problem.
At present, the method for wastewater disinfection mainly contains dosing sterilization, ultraviolet sterilization, ozone disinfection both at home and abroad, but not ideal; The dosing sterilization can produce carcinogenic halohydrocarbon residue, and ultraviolet sterilization, ozone disinfection facility investment and working cost costliness are difficult to implement.
Summary of the invention
Purpose of the present invention is exactly to develop that a kind of less investment, running cost are low, the wastewater disinfection method of non-secondary pollution.
Wastewater disinfection method of the present invention is: sewage is introduced in the container of sealing, then to its heating, make its temperature be elevated to 〉=70 ℃, and keep more than one hour, like this with regard to the whole killing microorganisms of energy, germ, virus, parasitic ovum, reach the purpose of wastewater disinfection, the pasteurization of Here it is sewage also is pasteurization.The thermal source of heating sewage can be the heat of sun power, sewage self fermentation generation or the heat that combustion fuel produces.
Embodiment
In one embodiment of the invention, the inventive method comprises: the sewage lagoon of a sealing, a sun power sewage well heater and a sewage (waste water) recirculating pump, and sewage lagoon top has a vapor pipe to lead to the high-altitude, and valve control is arranged on the vapor pipe; During operation, utilize sewage (waste water) recirculating pump that the sewage of sewage lagoon bottom is delivered to sun power sewage well heater, return the sewage lagoon top after the heating, sewage is through constantly circulation, and temperature will rise gradually, up to 〉=70 ℃, and keeps more than one hour.
Claims (2)
1. the pasteurization of a sewage is characterized in that: sewage is introduced in the container of sealing, then to its heating, make its temperature be elevated to 〉=70 ℃, and keep more than one hour, like this with regard to the whole killing microorganisms of energy, germ, virus, parasitic ovum, reach the purpose of wastewater disinfection.
2. the pasteurization of sewage according to claim 1 is characterized in that: the thermal source of heating sewage can be a sun power.
