Sewage self automatically-cleaning system

Abstract

The invention discloses a sewage self automatically-cleaning system. The sewage self automatically-cleaning system includes a sewage container, a water pump, a heating unit, an electric control unit,a motor, a stirring rod, a aeration unit, a carrier particle, a microorganism cultivating container, a heat preservation layer and an electric valve. The water pump is used to pump out sewage in the sewage container, send the sewage to the heating unit and slowly heated, and then send the sewage to the microorganism cultivating container; the preservation layer is arranged outside the sewage container and the microorganism cultivating container in a wrapping manner; the aeration unit is used to send oxygen to the bottom of the microorganism cultivating container; the motor drives the stirringrod to stir the carrier particle in the microorganism cultivating container and enables microorganisms to fall off; the sewage mixed with a large amount of microorganisms is sent to the sewage container through the control of the electric valve; the water pump, the heating unit, the motor, the aeration unit and the electric valve are all controlled by an electric control unit. The sewage self automatically-cleaning system disclosed by the invention has good cleaning capability, performs degradation and removes pollution by utilizing the microorganisms carried in a water body, causes no secondary pollution, and is extremely suitable for cleaning treatment of sewage water bodies such as brooks and ditches.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a self-automatic sewage cleaning system. Background technique [0002] In recent years, my country's water resource pollution has become increasingly serious, especially recently, at least 100 million tons of sewage from cities and towns across the country are discharged directly into water bodies without treatment every day. The water quality of more than half of the country's seven major water systems is polluted, one-third of the country's water bodies are not suitable for fish survival, one-quarter of the water bodies are not suitable for irrigation, 90% of urban waters are seriously polluted, and 50% of urban water sources are not suitable. According to drinking water standards, 40% of the water sources are no longer drinkable, and 60%-70% of the total water shortage in southern cities is caused by water source pollution. From 2006 to 2015, the total amount of wastewater dis...

Problems solved by technology

Most of the existing sewage treatment devices use physical or chemical methods, of which physical methods mainly use physical action to separate insoluble substances in sewage. Commonly used are gravity separation, centrifugal separation, reverse osmosis, air flotation, etc. The degree of sewage treatment The chemical method is a method of using chemical reaction to treat or recover the dissolved or colloidal substances of sewage. Commonly used methods include coagulation method, neutralization method, redox method, ion exchange method, etc., and the cost is relatively high, and Requires secondary processing, the process is cumbersome

[0003] At present, sewage treatment can use the purification ability carried by microorganisms, which has a high degree of treatment and low cost, but the conditions required for the growth and reproduction of microorganisms are very harsh: if the temperature is too high, the microorganisms will be killed, and if the temperature is too low, the growth and reproduction speed of microorganisms will be reduced. It will be very slow; if the oxygen content is too low, it will also inhibit the growth and reproduction of microorganisms, so it is necessary to strictly control all indicators
