Description

Centralized recycling system for building wastewater

technical field

The utility model relates to a wastewater recycling system, in particular to a centralized recycling system for building wastewater.

Background technique

At present, in the dormitory buildings, teaching buildings, laboratory buildings, library buildings and other buildings of colleges and universities, there is a large amount of domestic wastewater every day, such as domestic wastewater such as washing and cleaning, which belongs to high-quality miscellaneous drainage in urban domestic sewage and has a high recycling value. How to concentrate and recycle these domestic waste water is a very good way to save water.

Contents of the invention

The purpose of the utility model is to provide a system for centralized recovery and utilization of building waste water.

In order to achieve the above object, the utility model takes the following technical solutions:

The building waste water centralized recycling system described in the utility model includes a turnover storage tank arranged on the top floor of the building, and a filtered water tank and a sedimentation storage tank arranged on the bottom floor of the building; the filtered water tank is connected to the The sediment storage tanks are connected, and the bottoms of the filtered water tank and the sediment storage tank are respectively connected with the external waste water well through the sewage pump; The upper parts of the turnover water storage tank and the sedimentation water storage tank are respectively provided with the first and second rotating spray pipes controlled by the industrial computer. The flushing port of the pool is connected; an automatic filter is arranged on the upper part or outside of the inner cavity of the filtered water tank, and the automatic filter is composed of an overflow water tank with an upper opening structure, a filter orifice plate arranged at the upper opening of the overflow water tank, and The third rotary jet tube controlled by the industrial computer is set above the filter orifice; the upper part of the automatic filter cavity is respectively connected with the drainage pipes of the washing pools on each floor of the building through the waste water pipeline, and the automatic filter The bottom is connected with the outdoor sewage well through pipes and control valves.

The advantage of the utility model lies in the centralized recycling and utilization of domestic wastewater in buildings. During the centralized recycling process, the hair and dirt in the domestic wastewater are automatically filtered and discharged in real time. Sewage discharge has remarkable filtering effect and continuous, stable and reliable working performance, which can reduce the deterioration of water quality snake venom and aggravate peculiar smell. It has a high degree of automation and does not require personnel to be on duty and clean up. The sewage recovery rate is high and the water saving effect is remarkable.

Detailed ways

As shown in Figures 1-4, the building waste water centralized recycling system described in the utility model includes a turnover water storage tank 1 arranged on the top floor of the building, and a filter water tank 2 and a sedimentation water storage tank 3 arranged on the bottom floor of the building; The filtered water tank 2 is communicated with the precipitation storage tank 3 through a diversion pipe, and the bottoms of the filtered water tank 2 and the precipitation storage tank 3 are respectively communicated with the external waste water well 5 through sewage pumps 4.1, 4.2; the turnover of the top layer The water storage tank 1 is connected with the outlet of the water supply pump 6 provided in the sedimentation water storage tank 3 through a pipeline, and the first and second rotary spray pipes controlled by the industrial computer are respectively arranged on the upper parts of the turnover water storage tank 1 and the sedimentation water storage tank 3 7, 8, the water outlet of turnover storage tank 1 is respectively connected with the flushing ports of large and urinals 9 and 10 on each floor of the building through flushing pipes and control valves; the upper part of the inner cavity of filtered water tank 2 is provided with an upper opening structure The overflow water tank 11, the upper opening of the overflow water tank 11 is provided with a filter orifice 12, and the top of the filter orifice 12 is provided with a third rotary spray pipe 13 controlled by an industrial computer; the overflow water The top of case 11 inner cavity is communicated with 14 drain pipes of each layer of building washing pool respectively by waste water pipeline, and the bottom of overflow water tank 11 is communicated with external waste water well 5 by pipeline and control valve.

The working principle of the utility model is briefly described as follows:

The waste water discharged from the washing pools 14 on each floor of the building is discharged into the overflow water tank 11 through the pipeline, and the waste water will form a swirl state in the overflow water tank 11 due to the flow velocity of the water, and the water in the swirl state will dissipate the water in the overflow water tank 11. Hair and long fibers form a horizontal state in different flow velocity layers and rotate with the water flow, so the hair and dirt in the water will not pass through the filter hole plate 12 at the opening of the overflow water tank 11; the filtered water passes through the filter hole plate 12 It overflows into the filtered water tank 2 under the form of self-flow. When the overflow water tank 11 reaches the set sewage discharge time, the valve controller opens the electric control sewage valve 15 to discharge sewage into the external waste water well 5 under program control, and at the same time, the third rotating jet pipe 13 connects the external water source to the filter orifice plate 12 Cleaning is carried out from top to bottom, and the third rotating spray pipe 13 rotates and sprays under the reverse thrust of water to achieve the purpose of comprehensively cleaning the filter holes of the filter hole plate 12 .

After the water in the filtered water tank 2 enters the sedimentation storage tank 3 through the pipeline for sedimentation, the water is supplied to the turnover storage tank 1 on the top floor of the building through the water supply pump 6 and the pipeline arranged at the bottom of the sedimentation storage tank 3, so as to provide stool for each floor of the building. The flushing water of pond 9, urinal 10.

Since the sewage pumps 4.1 and 4.2 are respectively arranged at the bottom of the filtered water tank 2 and the sedimentation storage tank 3, there is no requirement for the installation height and installation site of the filtration water tank 2 and the sedimentation storage tank 3, and they can be half-buried underground. Installation and construction, which not only saves installation space but also reduces installation and construction costs.

Installed on the top of the turnover water storage tank 1 and the precipitation storage tank 3, the first and second rotating spray pipes 7 and 8 controlled by the industrial computer are connected to the external water source regularly according to the set time to the turnover water storage tank 1 and the precipitation storage tank. 3. The inner wall is jet cleaned.
