Urban sewage treatment status quo and problems: our major cities have polluted rivers, because the river mobility, changes, using the conventional method, which uses artificial and mechanical dredge the river, can not cure the problem of pollution of rivers , pollution of rivers in the world belongs to the forefront of technology. 1999 10 menstrual approved by the provincial Department of Environmental Protection, and in support of the EPA under Haikou City, on October 27 start date Datong ditch in the sea Galaxy Road area 30 meters long, 20 meters wide and 2.0 meters deep production of engineering test run on the river. The river is located in Haikou city, nearly 5 kilometers in length, due to the large number of urban sewage discharged into the river, the river is heavily polluted sludge master of small lot production and environmental protection equipment, water backflow, blue algae continue to breed, odor concentration, black river, over the years the people called "drainage ditch." In recent years, the city government has also repeatedly Qingtao river bed, but the effect was not significant, symptoms not causes. The use of "WT - FG" post-biological treatment, the total elimination of odors within three days, after two months of treatment, the water becomes tasteless, colorless. Transparent water, sludge by 45 centimeters, reduced to 8 cm, there 2000--2400 tons of contaminated water a day upstream through the river; sewage effective governance, the water quality up to the national "Surface Water Quality Standards" Class 4 standard, dissolved oxygen 5--6mg / L, COD = 20--3Omg / L, BOD5 = 5--6mg / L, transparency 0.5--1.2 meters, the river after the current process has been You can fish, there are more than 200 pieces of red goldfish and red carp have been in the river healthy survived more than four months smelting environmental equipment, Haikou Municipal People's widely praised for the people made a great thing. Reflux regulating weir within the integrated wastewater treatment equipment maintenance manual door operation: installation and commissioning of integrated wastewater treatment equipment reflux ball Grease the door section, check the two 0-ring for damage, then the door ball seat assembly axis device. Reflux door with the door shaft device erected, reflux door should be left part and the bottom 20 - 40mm gap. Measuring reflux door recessed flange distance to the top of the pool, from which to adjust the position of the bearing support means. The support means from the top down-hole, flange connection bump, the overall degree of vertical leveling, note that the center of rotation reflux door, horn contact surface should be greater than 80%, allowing only the superposition of two horns. Barring reflux door, check the working status of compliance. After hoist and bracket assembly, overall hoisting. Special Note: The opening range hoist 900, which should correspond to the opening of the reflux of the door. After connecting couplings bump in the lifting state, the real stand pad and spot welding. Barring hoist, check the working status of Circular Flow door, full throttle should be commissioning a few times to confirm eligibility before the bracket weld and embedded parts. Reflux regulating weir within the integrated wastewater treatment equipment maintenance and maintenance of the door without special maintenance and repair, support device is recommended every six months to check the situation of bearing grease. Reflux adjustable weir gate shutdown procedures and requirements to stop the water before stopping the use mud valve sleeve, the sleeve valve to the outflow of water, mud proof is completed, before stopping in the integrated wastewater treatment equipment. If you stop for more than two hours before the start of the bottom should detect whether the sludge sedimentation, if sludge is first closed sleeve valve factory environmental equipment, to the pool water, the water level reaches the normal position, and then turn the sleeve Mud valve environmental protection equipment, when the outflow of water from the sleeve valve before starting.
