Description
Technical Field
The invention relates to the field of water pollution treatment equipment, in particular to a chain net for quickly intercepting sewage and removing silt.
Background
The urban river channel refers to a natural or artificial water channel used for flood control, waterlogging drainage, water storage, drainage and shipping in urban areas. At present, most urban rivers have the functions of taking the functions into consideration and simultaneously taking the sewage receiving function into consideration. Various urban sewage, especially domestic sewage, is partially discharged into a river channel, so that the original ecological function of the river channel is unbalanced, the river channel is black and smelly, and the urban image is influenced.
The formation of black and odorous watercourses is caused by various reasons, wherein one of the main factors is excessive sewage receiving, so that the oxygen supply and the oxygen consumption of the water body are unbalanced. Industrial wastewater, urban domestic sewage, farmland fertilizer and pesticide and other pollutants are discharged into a river channel arbitrarily, so that the water body of the river channel is deteriorated, partial pollutants are accumulated and form black and odorous sludge at the bottom of the river channel, the original biological death and decay in the water body emit fishy and odorous odor while the water body is polluted, the total amount of the pollutants received in the water body in the years is far more than the self-purification capacity of the water body of the river channel, and the water body is blacked and odorous and the bottom is seriously silted.
The polluted condition of the black and odorous water body is complex, the polluted water body can be repaired by combining physical, chemical, biological and other combined means, the physical desilting is a basic procedure of various means for treating the pollution of the river channel, the conventional method for removing the deposited sludge in the river channel mostly adopts a physical excavation mode, the time and the labor are consumed, the centralized sludge excavation method is usually carried out at intervals for a long time, the effective pollution treatment is difficult to continuously maintain, the pollution treatment capacity of other combined treatment means is reduced to a certain extent, and the pollution treatment period is prolonged.

Furthermore, the height of the sewage intercepting net is higher than that of the fixed column sliding area.
Furthermore, a plurality of balance weights are arranged and evenly distributed along the lower edge of the balance weight chain.
In the technical scheme, the two ends of the floating ball chain are sleeved on the upper edges of the fixed column sliding areas of the two adjacent fixed columns through the floating ball chain sliding rings and can freely slide along the fixed column sliding areas.
As an effective scheme, the material of the sewage interception net is a flexible water retaining material made of synthetic fibers.
The invention has at least the following advantages:
1. compared with the mode of intensively excavating black and odorous sludge of a river channel at long time intervals and treating pollution of the river channel, the rapid dirt-intercepting and silt-removing chain net is arranged in the river channel, the black and odorous sludge is intercepted and in the dirt-intercepting net by water flow scouring, and can be lifted in a turning way through the movable column, so that the up-and-down shifting and sliding mechanism slides along the sliding area of the movable column and the sliding area of the fixed column and drives the dirt-intercepting net to wrap, deposited black and odorous sludge, large-particle insoluble substances and sand particles in the river are quickly wrapped in the dirt-intercepting net, and the dirt can be cleaned by means of manual transfer or other small mechanical auxiliary transfer, high efficiency and convenience are realized, and the assistance of a large-scale excavating instrument is not needed;
2. the design height of a fixing column for river channel treatment is higher than the peak water level, the design height of a flexible water retaining material is higher than the depth of water in a river channel to be treated and lower than the peak water level, and when the design scheme is used, the flexible water retaining material is easily torn under the condition that the water level is high and the water flow is rapid, and even the whole sewage intercepting chain net is destroyed; the flexible sewage interception net adopts a sewage interception net which is not lower than the flood peak water level of the river channel. When the river water level is in the normal range, gentle cut dirty net is the flexible crooked state, because cut the action of gravity of the counter weight chain at dirty net lower limb, make cut dirty net lower limb hang down in the river course river bottom to have the effect of holding back to river sewage, black smelly silt, middle and large granule undissolved substance and sand grain in the river, wrapped up in flexible cut dirty net lower limb enclosure, under the condition that the river rivers are hurried to the water level height, the lifting movable column makes cut dirty net package filth, when avoiding rivers to erode and cut dirty net but cut dirty chain net destroyed, avoid rivers to erode filth to low reaches and enlarge the pollution zone.
3. Compared with the direct fixing mode, when the peak water level of a river occurs, the floating ball chain pulls the sewage interception net to rise along with the rise of the water level due to the buoyancy action of the floating ball chain, and the sewage interception net is not lower than the height of the peak water level of the governing river channel, and under the gravity action of the counterweight chain of the sewage interception net, sewage is rolled in the sewage interception net no matter the height of the water level, so that the integral sewage interception effect is ensured; when the lower edge of the sewage intercepting net is longer than the upper edge, the lower edge of the sewage intercepting net can intercept more sewage, and the overall sewage intercepting effect is improved.
