Description
Technical Field
The utility model relates to a drainage facility, in particular to a gutter inlet filtering and dirt-intercepting hanging basket capable of improving the discharged water quality and easy to clean.
Background
Along with the comprehensive popularization of sponge city construction in China, the requirement of the sponge city on rainwater discharge water quality is becoming stricter day by day, the rainwater inlet is used as the last link of rainwater entering a rainwater pipe network in a sponge system, if a device can be installed in the rainwater inlet to play a role in purifying rainwater, the quality of rainwater discharge water quality is changed, and the problem of non-point source pollution control in the sponge city construction is solved.
At present, a plurality of newly developed devices can be installed in a gutter inlet to achieve the effective dirt interception and SS (suspended solid) removal capacity, but the devices cannot be effectively popularized, and the reason is summarized that the devices are relatively complex and have high manufacturing cost; part of equipment can not ensure the safety of the drainage system under strong rainfall; and the equipment with the SS removing capability needs to be cleaned or backwashed regularly to ensure the removal efficiency and speed of pollutants, but the cleaning of the equipment can only be carried out manually at present, the cleaning time is long, a large amount of manpower, material resources and financial resources are required to be invested in the frequent rainfall season for maintenance, and the operation and maintenance cost of the sponge city is greatly increased.
In summary, it is an urgent need to solve the technical problems of the present technology to find an apparatus or method that is economical and practical, can achieve efficient cleaning, and has a good decontamination effect.
Patent application CN107476412A discloses a gutter inlet filters cuts dirty basket and application method, and this application provides a gutter inlet filters and cuts dirty basket, should cut dirty basket and install in the gutter inlet, and upper portion and gutter inlet frame are connected, and the lower part is installed the filter screen, and the filter material in the filter screen basket adopts the form that geotechnological cloth is bagged, can cut dirty and play the ability of getting rid of the SS effectively. However, the above-mentioned sewage intercepting basket has the following disadvantages:
1) the equipment is difficult to take out: although the equipment can effectively intercept dirt and play a role in removing SS, pollutants can be accumulated in the dirt intercepting basket at the lower part of the equipment, when filter materials need to be washed, the dirt intercepting basket and the pollutants in the basket are extremely heavy, and a single cleaner cannot take out the dirt intercepting basket by self power.
2) The cleaning of the filter material is time-consuming and labor-consuming: the rainwater grate is opened, the equipment in the rainwater port is taken out, the filter material is unloaded for backwashing, and the filter material is reassembled and then placed back into the rainwater port, so that the set of flow is completed, and the fastest efficiency of two persons is required to be 30 minutes; and needs to be matched with a flushing water vehicle and a sewage suction vehicle for synchronous operation. The clean within range of municipal administration cleaning staff people all contain the inlet for stom water number and exceed 200, consequently wash this inlet for stom water and not only consumed manpower and materials greatly to can not satisfy the requirement of sponge city to the inlet for stom water washing time limit.
Patent No. CN201710331867 discloses a block-resistant sewage-intercepting hanging basket with a function of controlling non-point source pollution, when wastewater with solid particles or suspended pollutants enters into a rainwater inlet, and enters into the sewage-intercepting hanging basket through a diversion frame, the pollutants are intercepted and filtered, and the filtered wastewater is converged into a rainwater pipeline through a filtering hole or a clear water tank of the sewage-intercepting hanging basket to flow away. When the filter screen is blocked, the water level rises to a certain height, siphon is formed in the siphon, backwashing is started, and the blockage of the filter screen is relieved. However, the hanging basket has the following disadvantages:
1) the backwash effect remains questionable as it has been calculated that backwashing of the screen requires a head of water of more than 5m, whereas the gutter inlet is generally at a depth of about 1m, although this patent can utilise the siphon principle for backwashing, the siphon head does not reach the pressure required for flushing and hence backwashing is not readily achievable.
2) The equipment maintenance is difficult: just need take out when can not automatic backwash after the filter screen blocks up and wash, need to have a certain amount of water when this equipment normal use, consequently when depositing water the state, this equipment weight is very big, and when the filter material blocks up and can not automatic backwash, if want to take out equipment, will be a trouble that wastes time and energy only by the manpower, has greatly improved the human cost.
3) When the equipment is normally used, a certain amount of water needs to be stored, and if the equipment does not rain for a long time, the water body is easy to smell and deteriorate, so that the surrounding environment is seriously influenced; if the equipment is used in the north, if the stored water in the equipment is not emptied in winter, the equipment is very easy to be frozen and cracked, and the maintenance cost of the equipment is increased.
4) The municipal gutter inlet drawing set provides that the inner diameter of the gutter inlet is 380 x 680mm, the relevant specifications provide that the water passing capacity is not less than 12L/s, the equipment has the safe drainage capacity, the equipment does not have an emergency drainage channel, and the siphon drainage channel of the equipment manufactured under the size of the gutter inlet does not meet the drainage strength requirement of 12L/s, so that the potential safety hazard of rainwater drainage exists.
5) The sewage backwashed by the equipment is directly discharged into a rainwater system, and the problem of pollution control is not solved.
