At present, a filler is required to be put in a filler pool of a biochemical section of water treatment for attaching microorganisms to increase the microbial biomass, and a filler interception device is arranged in the filler pool of the water treatment to prevent the filler from flowing out of the filler pool. However, the filler is always piled up on the filler interception device before flowing to the interception device along with water flow, and the piled up amount is larger and larger along with the time, so that the filler interception device is blocked, in order to avoid blocking and slow down the piling up, the technical means adopted in the prior art are that a propeller in a filler pool is increased, the flow speed is accelerated, the piled filler is dispersed by utilizing the water flow impact, and the mode has high energy consumption and can generate abrasion on the filler and equipment; or the accumulated filler is led out to the front end of the filler pool by a special screw centrifugal pump and recycled, but the method has high energy consumption and can bring a large amount of water to the front end.
In practical engineering experience, the two methods cannot avoid the problem of shutdown caused by excessive packing accumulation due to machine faults, and serious packing accumulation affects the water treatment efficiency, and even more, once the packing accumulation is excessive, the packing overflows out of the water treatment tank, serious production accidents can be caused. Therefore, the work of evacuating and stacking the fillers cannot be ignored, and for a water treatment pool with huge volume, the work of evacuating and stacking the fillers generally needs to be stopped for one week, so that corresponding upstream and downstream processes are forced to be stopped, the economic loss is generally hundreds of thousands of times per day, and the ecological environment protection risk is higher for sewage treatment.

Detailed Description
The invention is further described below with reference to the accompanying drawings.
Wherein SIFAS refers to: the S-SYSTEM SYSTEM, the IFAS process and the hardware facility are integrated into a SYSTEM. IFAS refers to a biofilm/activated sludge combined process.
As shown in fig. 1, the upstream surface of the filler interception device 1 is the front, the back surface is the back, and water flows from the upstream surface to the back surface through the filler interception device 1. The filler collecting device for the water treatment SIFAS system is characterized in that a filler intercepting device 1 is arranged in a water treatment tank, and a collecting groove 2 is arranged behind the filler intercepting device 1. The filler interception device 1 is arranged in a filler pool, and in most cases is arranged in front of the water outlet 7, and possibly is arranged at the tail end of a filler zone, the filler interception device 1 is used for intercepting the filler 3 in water, the filler 3 is sometimes called a carrier or a filter material, microorganisms are attached to the filler 3 for decomposing pollutants in the water, the filler 3 is generally granular, and the filler 3 moves freely in the pool and has an internal multi-gap structure, so that the surface area for attaching the microorganisms is large. The packing 3 can only function in the water treatment tank and once the packing 3 leaks out or overflows the water treatment tank, serious production accidents occur. In order to ensure the safety of filler interception, the upper edge of the filler interception device 1 can be higher than the liquid level in the water treatment tank by a certain distance, lower than the liquid level by a certain distance or be kept level with the liquid level, in any case, the filler can safely overflow from the upper part of the filler interception device, an aggregate groove 2 is arranged behind the upper edge of the filler interception device 1, the front end of the aggregate groove 2 is attached to the filler interception device 1, the front end of the aggregate groove 2 is lower than the upper edge of the filler interception device 1, and the aggregate groove 2 is used for receiving the filler overflowed from the filler interception device 1.
When the length of the aggregate ditch 2 is the same as that of the filler interception device 1, the aggregate ditch 2 integrally extends along the length direction of the filler interception device 1 and keeps consistent with the trend of the upper edge of the filler interception device 1. The collecting channel 2 may be of the sectional type, and a plurality of collecting channel 2 units are combined with each other to form one collecting channel 2, and particularly in the case of a special pool shape and a plurality of collecting systems coexist, the collecting channel 2 does not need to be arranged behind the whole filler intercepting device 1.
As the water treatment pool runs, the filler 3 is continuously piled up in front of the filler interception device 1 along with water flow, when the filler 3 is piled up more and more, under the action of mutual friction and pushing among the water flow, aeration and the filler 3, a continuously ascending filler pile 4 is formed in front of the filler interception device 1, and when the height of the filler pile 4 is higher than the upper edge of the filler interception device 1, the filler 3 at the top can fall into the aggregate ditch 2; the filler 3 in the aggregate ditch 2 can be collected and put into the water treatment tank again, so that the water treatment tank is continuously operated.
The upper edge of the filler interception device 1 can be higher or lower than the liquid level in the water treatment tank by a certain distance, when the upper edge of the filler interception device 1 is higher than the liquid level, the filler pile 4 firstly climbs to be higher than the liquid level, and then continuously climbs to exceed the upper edge of the filler interception device 1 so as to fall into the aggregate ditch 2, and in this way, the liquid in the aggregate ditch is little. The distance between the upper edge of the filler interception device 1 and the liquid level should be a section of safe overflow distance, and the safe overflow distance refers to the condition that when filler is piled up to cross the upper edge of the filler interception device 1, the filler is not piled up to overflow the water treatment pool, and the condition that the safety and the filtering performance of the filler interception device 1 are not influenced by the packing accumulation can not occur. The safe overflow distance above the liquid level is generally not more than 30cm, and for a water treatment pool with serious accumulation and high accumulation speed, 20cm can be generally adopted. The packing 3 packing height depends on many factors, such as: filler input ratio, filler specific gravity, aeration, water flow speed, filler interception device 1 area and filler interception device 1 structure.
The upper edge of the filler interception device 1 can be lower than the liquid level, and the filler 3 at the top of the filler pile 4 enters the collecting groove 2 together with water flow at the moment as shown in fig. 2, but because the density of the filler 3 is generally lower than that of water, the filler 3 gathers on the liquid level, the amount of the filler 3 entering the collecting groove is large, and the distance between the upper edge of the filler interception device 1 and the liquid level is controlled to be not greater than a safe distance, otherwise, the water ratio in the collecting groove is excessively high. The maximum distance between the upper edge of the filler interception device 1 and the liquid level can reach 80cm, and when the filling density of a filler pool is small and the packing speed is small, the conveying amount is required to be small, and the distance can be shortened by 60cm, 40cm, 20cm or less.
The upper edge of the filler interception device 1 can also be kept level with the liquid level. In order to randomly adjust the distance between the upper edge of the filler interception device 1 and the liquid level, the upper end of the filler interception device 1 is arranged to be liftable. The movable connection mode can be adopted between the lifting part at the upper part and the fixed part at the lower part of the filler interception device 1. The liftable part of the filler interception device can also be realized by adopting a mode of lapping and dismantling the movable weir body, and the movable weir body unit can be made of plates, sectional materials and the like.
The filler interception device 1 as a whole can be in the form of a cartridge type interception net 5, a plate type interception net or a combined interception net, or other filler interception devices used in the industry. As shown in fig. 2 and 3.
The cross section of the aggregate ditch 2 is U-shaped, V-shaped, wedge-shaped with upward openings, rectangular or other polygons; the cross-sectional shape and size can be specifically selected according to practical situations and technical requirements, such as packing stacking speed, packing transferring mode and the like, for example, packing collection amount is large, then a larger cross section is possibly needed, for example, an instrument is adopted to transfer packing, then the cross-sectional shape is matched with transferring equipment, the aggregate ditch 2 can also be in a variable cross-sectional shape, or the bottom part is inclined so as to be favorable for collecting packing 3 in one direction, and the like, and can be variously designed according to practical use requirements. The aggregate trench 2 may be built from construction materials or formed from sheet metal or plastic panels. For water treatment tanks that have been put into use, the modification according to the invention may not have the possibility of constructing the aggregate trench from building materials, and it is also possible to work the aggregate trench from sheet metal, glass fibre reinforced plastic materials, wood materials etc. can also be used.
The invention utilizes the characteristic that the fillers are piled up in front of the filler interception device and mutually pushed and climbed, so that the filler pile 4 arches out of the height of the filler interception device and falls into the aggregate ditch 2, thereby avoiding the shutdown caused by serious filler piling, having high filler output rate, safety and energy saving, and being applicable to various water treatment tanks needing to be filled with fillers.
