Abstract
The utility model discloses a cleaning sludge-discharge structure in a rotary table filter tank, which comprises a rotary table filter tank body, wherein the rotary table filter tank body comprises a main body frame, a core filter system filter screen, a drive system, a back flush system and an automatic control system; the core filter system filter screen is composed of an independent filter screen piece, a roller and a filter tank; the back flush system comprises a back flush water pump, a back flush sprayer, a back flush water pipe, a nozzle system, a sludge collecting tank and a sludge discharge pipeline; a cylindrical through hole is arranged in the roller; the sludge collecting tank is installed in the cylindrical through hole of the roller; and the other side of the sludge collecting tank is connected with the sludge discharge pipeline. The back flush sprayer is utilized to flush sludge on the filter screen piece away into the sludge collecting tank, the sludge is discharged by the sludge discharge pipeline on the sludge collecting tank, and the back flush sprayer in the shape of a Chinese character 'feng' is utilized to spray water more uniformly, thereby enhancing the work efficiency, and effectively removing the sludge on the filter screen piece.
Description
Technical field
The utility model relates to the cleaning pollution discharge structure in a kind of turntable filter chamber.
Background technology
Along with the scarcity day by day of water resource and the continuous increase of Urban Water Demand, the sewage after the recycling advanced treating has become the important step of water environment protection engineering." the urban wastewater treatment firm pollutant emission standard " of country's promulgation in 2002 be middle regulation (GB18918-2002), when sewage disposal plant effluent is introduced lake, river that dilution capacity is less as purposes such as townscape water and general recycle-waters, carry out the A standard of primary standard.Huai, Hai and Liao rivers and Tai, Chao and Dianchi lakes (as Taihu Lake, Chaohu, Dian Chi) in China, the Liaohe River Basin of Songhua River System, the important area of the south water to north, and water shortage in north china area water resources such as (as Hebei province, Shanxi Province, Inner Mongolia Autonomous Region) lacks serious area, the requirement of centering water reuse is more urgent.For the demand of the By Comprehensive Treatment For Waste Water, reusing sewage or the urban look water that solve these key areas, newly-built sewage treatment plant need increase advanced treating on the basis of original two stage treatment, once builds up the A standard that reaches primary standard; Built sewage treatment plant need carry out upgrading, increases advanced treating, by the B standard upgrade of primary standard to the A standard.
China is one of 13 poor-water countries in the world: along with China's expanding economy. the contradiction of supply and demand for the water resource is becoming increasingly acute.When conventional water resource more and more can not meet the mankind to the demand of water.Pay close attention to gradually some unconventional water resources.As dirty waste water resource etc.According to Ministry of Construction's planning, within 2010, city sewage effluent amount will reach 60,000,000,000 m
3.As national reusing sewage rate on average reaches 10%.By China National urban lack of water of normal time 6000000000 m
3meter.The reusing sewage amount can meet the lack of water demand of National urban substantially.
Existing conventional sewage second-level biological treatment can't meet the requirement of regeneration, generally should adopt coagulation one precipitation one filtering technique or membrane technology _ 2J in feedwater to carry out advanced treating.But do like this and make that sewage operation facility is complicated, operating cost is high.It is 400～600 yuan/m that investment is processed in regeneration on municipal sewage treatment two stage treatment basis at present
3d, and. the membrane technology operating cost is high.According to investigations, the most sewage treatment plants in Beijing adopt MBR Process for Treating Municipal treatment plant secondary effluent, and the advanced treating cost approaches 1.5 yuan/m
3.
Summary of the invention
Technical problem to be solved in the utility model is that the structural design for solving the cleaning pollution discharge structure in prior art turntable filter tank is reasonable not, inefficiency, clean not thorough, the shortcomings and deficiencies such as water resource waste, and then provide a kind of and make the sprinkling of water more even, increase operating efficiency, effectively removed the cleaning pollution discharge structure in the turntable filter chamber of the dirt on the filter net sheet.
The utility model is achieved through the following technical solutions: the cleaning pollution discharge structure in a kind of turntable filter chamber, comprise the turntable filter chamber body, described turntable filter chamber body comprises by main body frame, core filtration system filter screen, drive system, backwashing system and automatic control system form, described core filtration system filter screen is by filter net sheet independently, cylinder and filter tank form, described backwashing system comprises anti-flushing water pump, the backwash shower nozzle, wash tub pipe, nozzle system, sewage collecting groove and blow-off line, described filter net sheet is arranged on the cylinder upper end, offer a cylindrical hole in described cylinder, described sewage collecting groove is arranged in the cylindrical hole of cylinder, the sewage collecting groove opposite side is connected with blow-off line, described backwash shower nozzle is arranged on the cylinder both sides by a horizontal water pipe, described backwash shower nozzle is connected with wash tub pipe.
As preferred technical scheme, described backwash shower nozzle is arranged on the both sides of horizontal water pipe, is " rich " font.
As preferred technical scheme, described sewage collecting groove be arranged on the backwash shower nozzle under.
The beneficial effects of the utility model are: the utility model utilizes the backwash shower nozzle that the spot on filter net sheet is rinsed and got off to drop to sewage collecting groove, by the blow-off line on sewage collecting groove, dirt is discharged, utilize the backwash shower nozzle of " rich " font, can make the sprinkling of water more even, increase operating efficiency, effectively known the dirt on the filter net sheet.
