Bathroom domestic wastewater reusing device

Abstract

The invention discloses a bathroom domestic wastewater reusing device. The device comprises a first water storage tank, a second water storage tank, a first water level sensor, a second water level sensor and a controller. The first water storage tank is connected with a drainage exit of a water basin, a drainage exit of a shower and a drainage exit of a washing machine through pipelines; the second water storage tank is provided with a first water outlet and a second water outlet, the first water outlet is connected with a water tank of a closestool, and the second water outlet is connected with a recycled water filtering system through a pipeline; the first water level sensor is arranged in the second water storage tank; the second water level sensor is arranged in the water tank of theclosestool; the recycled water filtering system is sequentially connected with a preliminary filter pool, a first precipitation pool, a pH conditioning pool, a biological nitrogen removal pool, a second precipitation pool and a recycled water pool; and the controller is connected with the first water level sensor, the second water level sensor and an electromagnetic valve. The device filters the drained water of the water basin, the shower and the washing machine, and then uses the drained water to flush the closestool and be gathered into the recycled water system, the water resources are effectively saved, and the wastewater utilization rate is improved.

Description

technical field [0001] The invention relates to the technical field of water saving, in particular to a device for reusing domestic sewage in toilets. Background technique [0002] At present, the water equipment or devices in the family bathroom include washbasins, washing machines, shower nozzles, flush toilets, etc., and a large amount of domestic water such as washing water, laundry water, and bathing water are generally directly discharged through the sewer, while toilet water The water is directly washed with clean water, and the waste of water resources is extremely serious. In order to save water, many families use containers such as buckets to store domestic water such as washing water, laundry water, and vegetable washing water for flushing toilets. However, these domestic sewage are stored in buckets for a long time. On the one hand, it is easy to breed bacteria, produce peculiar smell, pollute the air, and affect health; on the other hand, it also takes up space...

AI Technical Summary

Problems solved by technology

[0003] 1. The general operation is complicated, and the sewage purification rate is not high;

[0004] 2. The utilization rate of sewage is not high, it is only used for flushing toilets;

[0005] 3. The sewage in the toilet contains a large amount of detergent and other chemical components. The existing sewage treatment has not gone through the steps of removing the chemical components in the sewage, resulting in low utilization rate of sewage
