A method of domestic sewage and garbage collection and treatment based on decompression discharge technology

Abstract

A method for collecting and treating domestic sewage and garbage based on decompression discharge technology, including a gray water collection front end, a gray water treatment unit, a decompression black water collection front end, a decompression black water collection pipeline system, a decompression black water collection terminal, For the black water transfer unit and the organic fertilizer plant, the gray water enters the gray water treatment unit through the front end of the collection, and is discharged or reused after being treated according to the requirements of the effluent water quality. The front section of the collection, the decompression black water collection pipeline system enters the decompression black water collection terminal, enters the organic fertilizer plant through the black water transfer unit, and becomes organic fertilizer through the treatment of the organic fertilizer plant for use in the planting industry.

Description

1. Technical field [0001] The invention belongs to the technical category of sewage garbage collection and treatment, and in particular relates to a method for separately collecting and treating sewage generated in daily life such as laundry and bathing, feces, kitchen waste and the like by using a decompression discharge technology. 2. Technical background [0002] Common domestic sewage waste is usually collected and treated separately. The collection of domestic sewage is based on the principle of gravity discharge. All kinds of sewage are mixed together and enter the sewer system. After pretreatment in the septic tank, they are lifted into the sewage treatment plant through pumping stations for treatment. The septic tank sediment needs to be cleaned out regularly. Domestic waste is basically collected and transported manually, and then disposed of through harmless means such as landfill and incineration. The main disadvantages of the above sewage garbage collection and ...

AI Technical Summary

Problems solved by technology

The main disadvantages of the above sewage garbage collection and treatment methods include: (1) The water consumption is relatively large; due to the gravity discharge, the pollutants need to be washed with a large amount of water. Taking the toilet as an example, the current water consumption for flushing the toilet is about 6 liters; ( 2) The cost of sewage treatment is high, and it is difficult to recycle useful substances; all kinds of sewage are mixed together and discharged. In order to meet the requirements of discharge standards, they usually need to be treated by secondary biochemical and other sewage treatment processes. The cost of sewage treatment is high. The laundry and bathing sewage will dilute feces and kitchen waste, making it difficult to recycle useful substances such as easily degradable organic matter, nitrogen, and phosphorus; (3) The cost of garbage collection, transfer, and treatment is high; domestic garbage contains a large amount of raw garbage (mainly kitchen waste and plant residues, etc.), these wastes have high water content and are prone to corruption, which greatly increases the workload, difficulty and cost of collection and processing

The public document claims that feces fall into the feces storage tank through the back hole of the toilet, and urine flows into the urine storage barrel through the front hole of the toilet. This simple toilet lacking functions such as sanitation and deodorization ignores the people's increasing sanitary living needs. The utilization of feces and urine is also very primitive, and its practicality is limited
