Description

Vacuum toilet seat device

Technical Field

The invention relates to a sanitary ware, in particular to a vacuum toilet.

Background

The toilet bowl is a common article in daily life and is used for collecting excrement and waste water, the traditional gravity toilet bowl flushes the excrement into a sewer by using water, so that the flushing force is often weak, the toilet bowl is still not easy to flush even if a water tank is added, in addition, the water consumption is high, the odor is heavy, and the toilet bowl is easy to block, and aiming at the condition, a common toilet bowl treatment system needs to be redesigned.

Disclosure of Invention

The invention aims to solve the problems in the prior art and provides a vacuum pedestal toilet which can be flushed cleanly and reliably, is low in water consumption, good in trafficability and free of odor.

1. Apparatus and pipe assembly

A vacuum toilet is installed in each toilet and comprises a controller, an electromagnetic flushing system, a vacuum diaphragm valve and a toilet bowl or squatting pan entity. When a toilet flushing button is pressed, the vacuum toilet automatically finishes the whole flushing and sucking process, only takes several seconds, consumes 0.8 liter of water, sucks the high-concentration excrement and urine sewage into a vacuum pipeline system, and finally conveys the excrement and urine sewage to a vacuum waste sewage pump station; an area within three kilometers only needs one vacuum waste sewage pump station, which comprises a controller, a set of liquid level sensor, two vacuum pumps, two sewage pumps, a vacuum waste sewage tank and a set of tail gas treatment device; the whole pump station is completely in a closed state except that the discharge port of the tail gas treatment device is communicated with the atmosphere, so that the odor is prevented from overflowing; in order to facilitate vacuum conveying, a vacuum pipeline system adopts a sawtooth shape; because the whole drainage system adopts vacuum suction, the vacuum pipeline can freely go up and down, and the difficult problem that gravity flow is difficult to realize in mountainous regions, seasides, basements and low-terrain areas is effectively solved.

2. Analysis of economics

Compared with the traditional gravity flow toilet stool, the vacuum toilet system has the following economic advantages

(1) The water consumption of each flushing is only 0.8 liter, and the water is saved by 80 percent compared with the flushing water amount of 6 liters;

(2) a septic tank is not needed;

(3) may not be connected to municipal piping.

By applying the vacuum toilet system, the number of toilet visits of each person is calculated according to 6 times per day, and each person consumes about 5 degrees (kwh) of electricity per year.

The application of the efficient water-saving ecological drainage system can lead the municipal administration, the developers and the direct users to simultaneously profit; the direct user saves the cost by using less tap water and discharging less sewage; the municipal administration reduces the pressure of water supply and sewage treatment; developers make a profit by selling low cost reclaimed water. Taking ten thousand people as living units as an example, the running power consumption of the high-efficiency water-saving ecological drainage system is only 0.01-0.02 yuan/person/day, the system reduces the domestic water from 150 liters/person/day to 106 liters/person/day (44 liters/person/day is saved), only 6 liters of the 106 liters/person/day water is used for flushing a toilet, and in addition, 100 liters/person/day domestic miscellaneous water is recycled after simple treatment; the price of tap water is calculated according to 2.2 yuan/ton, the price of the treated reclaimed water is calculated according to 1.5 yuan/ton for commercial users such as car washing stations and the like, the cost of reclaimed water treatment is calculated according to 0.5 yuan/ton, so that for the residential area, direct users can save 16.06 million tons/year of water, the reclaimed water used for replacing tap water saves water by 36.5 million tons/year, the water supply is reduced by 52.56 million tons/year in municipal administration, developers (property) sell 36.5 million tons/year of low-cost reclaimed water, and the developers can obtain 36.5 million yuan/year.

The efficient water-saving ecological drainage system is used in the area where pollution discharge is controlled tightly and domestic sewage needs to be treated, so that the construction cost and the operation cost can be greatly saved. Taking a scenic spot as an example, the number of people served by the system is compared with the traditional gravity flow scheme: 5000 persons, squatting number: 300, all domestic sewage is required to reach the pollution-free discharge standard.

Traditional gravity flow scheme: 425 cubic meters per day of sewage needs to be discharged, 850 cubic meters of septic tank needs to be built, and one large sewage treatment station needs to be built.

The scheme of the high-efficiency water-saving ecological drainage system comprises the following steps: 220 cubic meters per day of sewage needs to be discharged, a septic tank is not needed, two central negative pressure stations are needed, 5 sets of vacuum sewage lifters are needed, and two sets of small sewage treatment stations are needed.

The following table makes a simple comparison between the cost of the two schemes and the cost of operation.
