When the first liquid level sensor detects that the water level in the pre-storage box is lower than the preset liquid level, municipal water can be fed into the pre-storage box through the water supply pipe, and after the municipal water entering the pre-storage box exceeds the first liquid level sensor, water supply can be stopped, so that the municipal water can be intermittently conveyed into the pre-storage box, and the water supply efficiency is improved. The water body in the pre-storage tank is conveyed into the fixed water tank through the siphon, so that the water body entering the fixed water tank is not influenced by the amount of the purified domestic sewage; therefore, the use pipe can continuously output water.

Description

Technical Field

[0001] The present invention relates to the field of domestic sewage purification, and in particular to a domestic sewage treatment system based on municipal water supply and drainage technology. Background Art

[0002] The municipal water supply and drainage system usually consists of a water source, a water pipeline, a water plant and a water distribution network. After taking water from the water source, it is sent to the water plant through the water pipeline for water quality treatment. The treated water is pressurized and sent to users through the water distribution network. The municipal water supply and drainage system is divided into rural water supply and drainage and urban water supply and drainage. At the same time, in the water supply and drainage technology, the treatment of domestic sewage can be said to be an extremely important link. When treating domestic sewage in rural areas, it is often achieved by setting up a multi-stage sewage purification structure to purify domestic sewage. However, the existing multi-stage domestic sewage treatment system can purify domestic sewage through a multi-stage treatment system during use, and the purified water body can be used for the normal life of residents, and combined with the municipal water supply and drainage system, so that the purified water body is matched with the water supply in the municipal water supply to meet the use of residents.

[0003] However, when residents use water, they will inevitably give priority to using purified water from domestic sewage due to municipal water supply charges. However, the amount of purified water from domestic sewage is often limited by the living conditions of the residents, which leads to fluctuations in the amount of purified water from domestic sewage. During the use of water, residents will inevitably find that the purified water from domestic sewage is unable to meet their needs, requiring them to re-open the municipal water supply, which affects their usage experience to a certain extent.

[0004] Therefore, when the above-mentioned domestic sewage treatment system is in use, the purified water of domestic sewage cannot meet the residents' usage needs, which will cause residents to spend extra time to activate municipal water supply, thereby affecting residents' water use experience.

[0021] Beneficial effects of the present invention:

[0022] 1. On the basis of the conventional domestic sewage treatment system, the sewage treatment structure is modified. When the first liquid level sensor detects that the water level inside the pre-storage tank is lower than the predetermined liquid level, the municipal water supply can be sent to the pre-storage tank through the water supply pipe. After the municipal water supply entering the pre-storage tank exceeds the first liquid level sensor, the water supply can be stopped, so that the municipal water supply can be intermittently transported to the inside of the pre-storage tank, so that the water supply inside the fixed water tank will not be wasted due to the fluctuation of the water supply of the liquid outlet pipe, and the water inside the pre-storage tank is transported to the fixed water tank through the siphon, so that the water entering the fixed water tank will not be affected by the amount of domestic sewage purified water, so that the water can be output uninterruptedly using the pipe;

[0023] 2. During the use of the device, it is inevitable that there will be too much purified water of domestic sewage. When the fixed water tank is filled with purified water of domestic sewage, the municipal water output from the pre-storage tank will cause the water inside the fixed water tank to overflow, resulting in a waste of water resources. The second liquid level sensor and the third liquid level sensor can cooperate with each other to achieve a double judgment of the liquid level of the water inside the fixed water tank, so that the water delivered by the pre-storage component can be controlled by the started second motor. At the same time, because the municipal water supply inside the pre-storage tank is intermittently delivered and is limited by the scarce water supply points in rural areas, it will cause a certain delay in the municipal water supply. This delay can be coordinated with the intermittent delivery to ensure that the water entering the pre-storage tank does not exceed the volume of the pre-storage tank, thereby preventing the waste of water resources in the domestic sewage treatment system to a certain extent.

[0024] 3. By setting a first hydraulic push rod to drive the push rod cover to slide along the positioning plate, and by using a second hydraulic push rod to drive the connecting plate to move along the connecting strip, the scraper plate can move along the sliding seat, so that the primary filter plate can move along the primary filter plate, and return to the top of the primary filter plate after moving to the bottom, so as to fully filter the domestic sewage retained on the primary filter plate, so as to improve the working efficiency of the entire domestic sewage treatment system.
