Electroplating wastewater containing metal ions mixed waste, chromium, copper, iron, zinc, nickel removal were more than 90%, the general electroplating wastewater can be treated to meet emission standards. Coal, mineral water turbidity allows 500-1500 mg / lift to 5 mg / liter. Printing and dyeing wastewater color removal 70-90% cellular ramp, COD removal of 50-70%. Leather, food industry waste a lot of organic matter removal, COD removal efficiency of 50-80%, more than 90% removal of solid impurities. 5, COD removal efficiency of chemical waste 60-70% 60-90% color removal, suspended solids up to emission standards. Sedimentation is defined as the area has a sedimentation tank precipitation oblique tube. Advection precipitation in the region or vertical flow sedimentation tank using a parallel or parallel pipes tilt tube (sometimes using the cellular filler) is divided into a series of shallow sediment layer, to be treated and the settlement of the sink in the mud in the shallow precipitation mutual movement and separated. According to its direction of motion is divided into mutually inverse (iso) to flow with the flow and reverse flow separation in three different ways. Each ramp between two parallel plates (or parallel tube) is equivalent to a very shallow sedimentation tanks. Its advantages are: ① use of the laminar flow principle, to improve the processing capacity sedimentation tank; ② reducing the particle settling distance, thereby reducing the precipitation time; ③ increase the sedimentation area of ??the sedimentation tank, thus improving the processing efficiency. This type of flow rate through the settling ponds up to 36m3 / (m2.h) cellular inclined tube material, higher than the average sedimentation 7-10 times the processing power, is a new and efficient precipitation equipment. And has been finalized for the production practices. Cellular ramp (ramp) | aerator - Several precipitation clarify Techniques (3) hydraulic rotating comprehensive clarification pond water power, water clarifiers are spin comprehensive northwest China Municipal Engineering Design Institute is able to handle high turbidity water flood non-treatment of low turbidity water can flood the design of a new clarifier, which is characterized by low turbidity of the treated water has a good effect of the hydraulic cycle clarifiers, and treatment of high turbidity water better results Rotary water clarifiers, whichever is the respective advantages of the two pools, organically combined into a pool, so a pool with two, solves the contradiction between the high turbidity water with low turbidity water between. ① water pressure water pressure and water requirements of the same spin characteristics required in accordance with the ejector, set by the central pool of water in the high turbidity water inlet pipe; low turbidity water from the bottom of the water inlet pipe to both solve the water pressure constant pumping station requirements; also solve two kinds of water quality inlet position different needs, and the operation is relatively simple. ② the same characteristics of the sludge water circulating pool collapse angle 45 ° inclined wall with high turbidity slag cement concentrating compartments 45 ° ~ 50 ° between the two unite, eliminating the high turbidity of the water scraper with bucket row mud instead. ③ with gland ring, a reflux valve, align the high turbidity water and low turbidity of the water and mud of the different reaction times required. The pool type in the Yellow River tributary Datong, put into operation after 1975, after years of operation and testing cellular inclined tube manufacturers, raw water sediment concentration around 60kg / m3 cellular inclined tube filler, can be normal water supply, water turbidity is still 30 ° or less. Raw water sediment concentration 30kg / m3 or less and the low temperature and low turbidity, the effluent turbidity can be at 20 ° or less. Gansu Province in 1985 as the outstanding design.
