THE PIPE SYSTEM FOR COLLECTING AND TREATING DOMESTIC WASTEWATER IN HIGH-RISE BUILDINGS

Useful solutions in the field of domestic wastewater treatment to protect the environment. Specifically, the useful solution refers to the pipe system for collecting and treating domestic wastewater in high-rise buildings, namely in apartment buildings, office buildings, hotels, mixed-use buildings, etc. complex, commercial center.

The technical nature of the useful solution:

The purpose of the useful solution is to overcome the above disadvantages.
To achieve that purpose, the useful solution proposes a wastewater collection and treatment system with only a single pipe, which is expanded to save electricity in the direction of increasing from high to low, combined with energy-saving devices and equipment. wastewater treatment equipment with MGB brand of Green and Green environment joint stock company. This system overcomes all the above disadvantages, bringing great economic efficiency and scientific, technical and environmental significance.

Due to the use of MGB wastewater treatment equipment (Patent Patent No. 1-0010272 of the same author) capable of simultaneously treating all types of domestic wastewater such as toilet wastewater, kitchen wastewater, etc. , wastewater from bathrooms and washing machines, etc., the collection and drainage system requires only a single drain pipe into which all types of domestic wastewater are collected to be taken to the treatment equipment. wastewater mentioned above. In addition, since the water collection and drainage system used for the first time a power dissipation device (described in the same author's Patent application No. 2-2012-01536) installed at the end of the Drainage pipes so the system does not need to have elbows to reduce the kinetic energy of wastewater.

With the cross-section of the pipe being widened as the wastewater flow increases, the system becomes neater, never clogged, so the number of pipe fittings and joints is greatly reduced.

The operation of the water collection and drainage system is as follows.
_ The top of the pipe is open (not sealed) to regulate the pressure in the pipeline. When the wastewater enters the pipe, it will participate in the free fall motion with the acceleration due to gravity. When the free fall movement encounters the resistance of the air, the water flow is broken into particles and falls similar to rain. The water falls and takes up volume in the tube so the air is forced and creates a high pressure so it moves up to the top of the tube (where the pressure is less) and out. The gas escapes by the volume of water displaced and carries with it some (negligible) emissions, which are diluted into the air but not enough to cause pollution.

_ Because PVC, PP-R, HDPE pipes are specialized drain pipes for the drainage industry, the retention and adhesion on the vertical axis is almost nonexistent. Then we only need to pay attention to the pipe cross section corresponding to the volume of wastewater to be drained.

_ All large wastes that do not dissolve in water will be kept in the power box to be taken out. Organic waste mixed in water will be put into MGB wastewater treatment equipment along with wastewater to be thoroughly treated. After treatment, qualified wastewater is discharged into the environment, the remaining residues will be periodically sucked and the collected garbage will be taken for further treatment at facilities specializing in hazardous waste treatment such as septic tanks. often.

_ The attached vent pipes, the probes, the crooked pipes are removed. The number of pipes and vertical shaft fittings is reduced by 80%.

The effect achieved by the useful solution:

A useful solution that provides a method of installing a vertical shaft drainage system for high-rise buildings to ensure the most ventilation, meeting all factors of drainage engineering and the environment. Ensure safety for users and safety for the project. When using this solution, the investor will enjoy the following benefits:

Decrease:
• 75%: Technical box volume
• 65%: Drainage pipes and fittings
• 100%: Septic tank
• 98%: Sump vapor and air pollution
• 60%: Investment capital for drainage and environment items (including technical boxes).

Increase:
• 75%: Useful floor area (area of technical box)
• 5 times: Life of work items
• 2.5 times: Construction progress of drainage and environment items
• 12 times: Speed to revive dead rivers and lakes in provinces
• 100%: Useful land area (land for wastewater treatment plant)
