Description

A rainwater inlet filtering sewage interception hanging basket that can improve the discharge water quality and is easy to clean

technical field

The utility model relates to a drainage facility, in particular to a rainwater gully filtering sewage interception hanging basket which can improve the discharge water quality and is easy to clean.

Background technique

With the comprehensive promotion of sponge city construction in China, the requirements of sponge city for the quality of rainwater discharge are becoming more and more strict. The rainwater inlet is the last link in the sponge system for rainwater to enter the rainwater pipe network. If a device can be installed in the rainwater outlet to purify the rainwater It will play a qualitative change in the quality of rainwater discharge, and solve the problem of non-point source pollution control in the construction of sponge cities.

At present, there are a variety of newly developed equipment installed in the rainwater outlet, which can effectively intercept sewage and remove SS (suspended solids), but this type of equipment cannot be effectively promoted. High; some equipment cannot guarantee the safety of the drainage system under strong rainfall; and these equipment with the ability to remove SS need to be cleaned or backwashed regularly to ensure the removal efficiency and rate of pollutants, but currently cleaning these The equipment can only be carried out manually, and the cleaning time is long. In the season with frequent rainfall, a lot of manpower, material resources and financial resources need to be invested in maintenance, which greatly increases the cost of operation and maintenance of the sponge city.

To sum up, it is an urgent technical problem to be solved by those skilled in the art to seek an economical and practical device or method that can achieve efficient cleaning and good decontamination effect.

The patent application of the patent application document CN107476412A discloses a rainwater gully filtering sewage intercepting basket and a method of use. The application provides a rainwater gully filtering sewage intercepting basket. The sewage intercepting basket is installed in the rainwater gully, and the upper part is connected with the outer frame of the rainwater gully. A filter screen is installed at the bottom, and the filter material in the filter basket is in the form of geotextile bags, which can effectively intercept dirt and have the ability to remove SS. However, the above-mentioned waste interception basket has the following disadvantages:

1) It is difficult to take out the equipment: although the equipment can effectively intercept dirt and remove SS, the pollutants will accumulate in the sewage interception basket at the bottom of the equipment. When the filter material needs to be washed, the sewage interception basket and the basket The pollutants will be extremely heavy, and it is impossible for a single cleaning person to take out the interception basket by himself.

2) Cleaning the filter material is time-consuming and laborious: open the rainwater grate, take out the equipment in the rainwater inlet, remove the filter material for backwashing, reassemble and put it back in the rainwater inlet. After this set of processes, the fastest efficiency for two people also takes 30 minutes. ; And it needs to be equipped with a washing water truck and a sewage suction truck for synchronous operation. There are more than 200 gullies per capita within the cleaning range of municipal cleaning staff. Therefore, cleaning the gullies not only consumes a lot of manpower and material resources, but also cannot meet the requirements of Sponge City for the cleaning time limit of gullies.

The patent No. CN201710331867 discloses an anti-clogging sewage interception basket with the function of controlling surface source pollution. When the waste water with solid particles or suspended pollutants enters the rainwater inlet and passes through the guide frame, it enters the sewage interception basket, The pollutants are intercepted and filtered, and the filtered wastewater flows into the rainwater pipeline through the filter holes of the interception basket or the clean water tank. When the filter screen is blocked and the water level rises to a certain height, a siphon is formed in the siphon pipe and backwashing starts, and the filter screen blockage is relieved. However, the above hanging baskets have the following disadvantages:

1) The effect of backwashing is questionable: after calculation, the backwashing filter needs a water head of more than 5m, and the depth of the general rainwater inlet is about 1m. Although the patent can use the siphon principle for backwashing, the siphon head cannot meet the needs of the washing. pressure, so backwashing is not easy to achieve.

2) Equipment maintenance is difficult: when the filter screen is blocked and cannot be automatically backwashed, it needs to be taken out for cleaning. The equipment needs to have a certain amount of water in normal use. Therefore, when the water is in the state, the weight of the equipment is very large and the filter material is blocked. If the equipment cannot be automatically backwashed, it will be time-consuming and labor-intensive only by manpower, which will greatly increase the labor cost.

3) A certain amount of water needs to be stored in the normal use of the equipment. If it does not rain for a long time, the water body will easily stink and deteriorate, which will seriously affect the surrounding environment; if the equipment is used in the north, if the water in the equipment is not drained in winter. If it is empty, it is easy to freeze the equipment and freeze it, which increases the maintenance cost of the equipment.

4) The atlas of the municipal rainwater outlet stipulates that the inner diameter of the rainwater inlet is 380*680mm, and the relevant specifications stipulate that the water passing capacity should not be less than 12L/s, and it should have the ability of safe drainage. The equipment has no emergency drainage channel, and the rainwater inlet The siphon drainage channel of the equipment made under the size cannot meet the drainage strength requirement of 12L/s, so there is a hidden danger of rainwater drainage.

5) The sewage backwashed by the equipment is directly discharged into the rainwater system, which does not solve the problem of pollution control.
