Domestic sewage treatment device

Abstract

The invention relates to the technical field of environmental protection devices and particularly relates to a domestic sewage treatment device. According to the domestic sewage treatment device, thefiltering is relatively sufficient, oil stains and other organic pollutants can be effectively removed from sewage, and the quality of disinfection can be improved. The domestic sewage treatment device comprises a main body, wherein a working chamber is formed in the main body. The domestic sewage treatment device is characterized in that four partition plates are vertically arranged in the working chamber, wherein the working chamber is partitioned into a filtering chamber, an oil removing chamber, an acidity/basicity adjusting chamber, an oxidation chamber and a disinfection chamber from left to right by the four partition plates. The domestic sewage treatment device further comprises activated charcoal, wherein the activated charcoal is located inside the filtering chamber. The domesticsewage treatment device further comprises a power supply and two electrode bars, wherein the power supply is located at the top end of the main body, the two electrode bars are electrically connectedwith the positive pole of the power supply and the negative pole of the power supply separately, the electrode bar connected to the positive pole of the power supply is made from aluminum, the two electrode bars are located inside the oil removing chamber, and an activated sludge layer is arranged at the bottom of the oil removing chamber. The domestic sewage treatment device further comprises aspiral pipe, a first connecting rack, a second connecting rack, a gas cylinder, a gas pump and a gas pipe, wherein the gas cylinder contains chlorine dioxide gas.

Description

technical field [0001] The invention relates to the technical field of environmental protection devices, in particular to a domestic sewage treatment device. Background technique [0002] As we all know, a domestic sewage treatment device is a device that uses physical, chemical and biological methods to treat wastewater and purify wastewater to meet discharge or reuse standards.

[0002] As we all know, a domestic sewage treatment device is a device that uses physical, chemical and biological methods to treat wastewater and purify wastewater to meet discharge or reuse standards. It has been widely used in the field of environmental protection; the existing The domestic sewage treatment device includes a main body. A working chamber is arranged inside the main body. A partition is arranged vertically in the working chamber. The partition divides the working chamber from left to right into a filter chamber, an acid-base adjustment chamber and a disinfection chamber. Sewage inlet, the sewage inlet is connected with the filter chamber, through holes are drilled on the partition between the filter chamber and the acid-base adjustment chamber, acid-base adjustment chamber and disinfection chamber, and filter screens are arranged in the through holes, and the upper part of the filter chamber There is a grid, the upper end of the acid-base adjustment chamber is provided with a conditioner inlet, and the upper end of the acid-base adjustment chamber is also equipped with an acid-base detector. The acid-base detector includes a display and a detector, and the display is electrically connected to the detector. On the upper end of the adjustment chamber, the detector is located in the acid-base adjustment chamber, the upper end of the disinfection chamber is provided with a disinfectant inlet, and the lower end of the disinfection chamber is provided with a water outlet; when the existing domestic sewage treatment device is in use, the domestic sewage is introduced from the sewage inlet for filtration The domestic sewage is filtered through the grid in the filter chamber, and then the domestic sewage enters the acid-base adjustment chamber to adjust the acid-base of the domestic sewage. Finally, the domestic sewage enters the disinfection chamber. After the domestic sewage is disinfected by the disinfection chamber, the water outlet can be opened to discharge it It is found in the use of existing domestic sewage treatment devices that the filtration is insufficient, the oil and other organic pollutants in the sewage have not been effectively removed, and the disinfection quality of many sewage is poor
