Description

A fully automatic road cleaning system

technical field

The invention belongs to the field of environmental protection, and in particular relates to a fully automatic road cleaning system.

Background technique

The urban roads in our country today are all cleaned by sprinklers. Sometimes the car is parked on the side of the road, and all the ash is swept into the car when it is sprinkled. You have to go back to wash the car yourself. When the sprinkler is working There will be some water splashed on pedestrians. The water is dirty water after washing the ground. At the same time, some citizens believe that the time of sprinkler operation at noon every day coincides with the peak period of vehicle traffic. , also brought pressure to traffic congestion. Secondly, the music horn of the sprinkler will disturb the people who are resting. If the horn is not turned on, it will be very unfair to pedestrians. Some pedestrians will not know that the sprinkler is coming, and the impact will be even greater. . As a result, the public will have a headache when they see it. Moreover, the vehicle exhaust emitted by sprinklers on urban roads will also pollute the air, and the economic efficiency is poor.

Water is the source of life, the key to production, and the foundation of ecology. The joint governance of five waters is a measure that kills many birds with one stone. It not only expands investment but also promotes transformation, which not only improves the environment but also benefits people's livelihood. Five-water governance refers to sewage treatment, flood control, drainage of waterlogged water, water supply protection, and water conservation. The water used by sprinklers is generally discharged directly to the sewer, that is, the municipal pipeline. The water consumption is large, and the water cannot be recycled, which also brings pressure to the joint governance of five waters.

When it rains, it absorbs, stores, infiltrates, and purifies water, and when needed, "releases" the stored water and makes use of it. Sponge city is a sustainable urban construction model described from the perspective of urban stormwater management. Its connotation is: modern cities should have the functions of absorbing, purifying and utilizing rainwater like sponges, as well as preventing climate change and extreme rainfall. The ability to reduce disasters and maintain ecological functions.

2. This application changes the traditional method of cleaning urban roads mainly by manual or mechanical operations, and changes the traditional fast drainage mode of the existing drainage system that only drains but does not store. Improve work efficiency, achieve the purpose of automatically removing road pollution by using rainwater and sewage, keep the road clean and tidy, and regularly irrigate the plants on the green belt.

3. The fully automatic high-pressure road cleaning device is mainly composed of a regulating tank, a sewage purification device, a reservoir, a high-pressure nozzle, a rainwater collection well, a temperature sensing device, an infrared sensing device, a high-pressure water pump, and a water pipe. The bracket on the "road shoulder stone" of the green belt on the roadside can move left and right to spray the water column to clean the road surface and cool down the road surface. The regulating pool, sewage purification device and water storage tank are placed in the underground pipe gallery for manual operation. At the same time, it is connected with some sewage pipes of the underground pipe gallery for spraying the road surface after purification. This set of devices will fully replace the current traditional method of cleaning roads manually or with urban road sprinklers, improve work efficiency, and achieve the purpose of recycling rainwater and sewage to automatically remove road pollution and keep roads clean and tidy.

4. The technical problem to be solved by the technology of the present invention is to control sewage, drain waterlogged water and grasp water conservation. For this reason, our device utilizes rainwater collection wells to collect the water when it rains and the waste water used for cleaning the road surface and the part of the underground drainage pipeline The waste water is treated by the reclaimed water circulation equipment and stored in the reservoir after meeting the water quality requirements. When the road needs water, the high-pressure water pump is turned on, and the water in the reservoir is sent to the nozzle through the water delivery pipe, and the road surface is treated by the nozzle. Spraying and cleaning and irrigating the plants on the green belt to completely change the traditional water use mode Through various technologies such as infiltration, stagnation, storage, purification, use, and drainage, change the existing drainage system. Quick sort mode. When there is a lot of water, drain and store water, and when it is needed, clean water and release water is similar to the principle of sponge absorbing and releasing water to solve the water problem on the spot.

It cannot be cleaned automatically and requires manual operation. impact on vehicles and pedestrians.

The above subdivision of the sewage purification plant includes the following equipment and steps:

1. The sewage enters the pool from the regulating pool:

The pool is mainly composed of three parts: anaerobic reactor, anoxic reactor, aerobic reactor-aeration tank, and its main functions are as follows:

1) Anaerobic reactor: the raw sewage and the phosphorus-containing return sludge discharged from the sedimentation tank enter the reactor simultaneously, and its main function is to release phosphorus and ammoniate some organic matter at the same time;

2) Anoxic reactor: Sewage enters the reactor through the anaerobic reactor, and its primary function is denitrification. The nitrate nitrogen is sent from the aerobic reactor through the internal circulation, and the amount of mixed liquid in the circulation is relatively large. It is 2Q (Q--the amount of raw sewage);

3) Aerobic reactor--aeration tank: The mixed liquid enters the reactor from the anoxic reactor, and its functions are multiple. BOD removal, nitrification and phosphorus absorption are all carried out in the reactor. These three items The reaction is important, the mixed solution contains NO3-N, the sludge contains excess phosphorus, and the BOD (or COD) in the sewage is removed, and the mixed solution with a flow rate of 2Q is returned to the anoxic reactor from here;

2. After the sewage is reacted in the pool, it goes through the secondary sedimentation tank:

The function of the secondary settling tank: mud and water are separated, a part of the sludge is returned to the anaerobic reactor, and the supernatant is discharged as treated water.

3. After passing through the secondary sedimentation tank, the sludge and supernatant are treated as follows:

3.1. The remaining sludge enters the sludge thickening tank:

The centrifugal concentration method is adopted in the sludge thickening tank.

The function of the sludge thickening tank: it is carried out in a specially manufactured centrifugal thickener. Using the different specific gravity of solid and liquid in the sludge, there are different centrifugal tendencies to separate the muddy water and achieve the purpose of concentration. And the concentrated sludge is compacted into a mud cake, which is regularly transported out manually.

3.2. The supernatant after being treated in the secondary sedimentation tank enters the sand filter:

The sand filter is a pressure filter using quartz sand as the filter material.

The role of the sand filter: it is a physical treatment in sewage treatment, which removes large particles in the water and can remove a small part of COD (chemical oxygen demand).

4. Enter the adsorption pool after passing through the sand filter:

The adsorption pool adopts activated carbon adsorption.

The function of the activated carbon adsorption pool: remove the peculiar smell in the water, remove the impurities in the water, and decolorize.

5. After passing through the activated carbon adsorption pool, it enters the clean water storage pool.

6. The treated water after entering the clean water storage tank has the following two purposes:

6.1. Used for backwashing sand filter.

6.2. Applied to road cleaning devices, to clean road surfaces and water green belts.
