Suction pollution discharge method and device for online air draft-on-site gravity pollution discharge

Abstract

Provided is a suction pollution discharge method for online air draft-on-site gravity pollution discharge. The method includes the steps that a container connected with a sewage discharging opening ofa toilet stool is included, the bottom of the container is provided with a normally-closed sewage discharging opening capable of being opened through the gravity of waste water generated by one-timedefecation, the sewage discharging opening is connected with an on-site waste water storage tank, and an air draft combination is arranged at the top of the container. Therefore, negative pressure canbe formed in the container by opening the air draft combination for a short time, so that the waste water in the toilet stool can be driven to be discharged into the waste water storage tank throughthe container.

Description

[0001] 1. Technical field [0002] The invention belongs to the technical field of environmental sanitation, and in particular relates to a method and device for suction and sewage discharge of online air extraction-in-situ gravity discharge of sewage. [0003] 2. Technical Background [0004] Suction blowdown is sometimes called indoor vacuum blowdown, vacuum source separation blowdown, and negative pressure source separation blowdown. An environmental sanitation system that cleans toilets and other sanitary ware and realizes high-concentration discharge and collection of sanitary waste. The sanitary waste water mentioned in the present invention specifically refers to the waste water used to discharge sanitary waste, and said sanitary waste includes excrement and kitchen waste, but does not include washing waste water such as bathing, laundry, and kitchen rinsing. The suction sewage mentioned in the present invention includes the process of transferring sanitary wastewater f...

AI Technical Summary

Problems solved by technology

As a result, there are several deficiencies in the actual application of the existing suction and sewage method: (1) the requirements for the vacuum pumping station are relatively high, which increases the cost of pumping station construction and operation; (2) the sealing requirements for the suction pipeline are relatively high. High, increasing the cost of pipeline laying and maintenance; (3) The sanitary ware at the user end needs to be connected to the suction pipe through a special sewage interface valve, and therefore usually requires the use of special sanitary ware at the user end; (4) due to the suction pipe In general, a high negative pressure is maintained, and a strong suction noise will be generated at the moment when the sewage interface valve is opened at the user end, which affects the user experience

When the above method is applied to scenarios such as rural sanitation, the cost of centralized suction pumping stations and suction piping systems is particularly high due to the scattered living in rural areas
