Technical Field
The invention relates to the technical field of water supply treatment, in particular to a high-turbidity water and low-temperature low-turbidity water treatment technology integrated device.
Background
In the conventional feedwater treatment technology, coagulation and precipitation are two important process units, wherein the coagulation is realized by adding a coagulant into raw water, fully mixing, enabling micro-flocculation particles to mutually contact and collide under the action of external force to form larger flocculation particles, and then separating the part of flocs from the raw water through precipitation. Because the grid flocculation tank has less flocculation time, good flocculation effect, simple structure, high sedimentation efficiency of the inclined tube sedimentation tank and small occupied area of the tank, the two are combined in the integrated water purification equipment and are widely applied to water supply treatment. In the coagulation treatment, the coagulant and coagulant aid used are the key of the treatment, the most used coagulant at present is polyaluminium chloride (PAC), and the commonly used coagulant aid is Polyacrylamide (PAM). The PAC dosage is too much, on one hand, the water treatment operation cost is increased; on the other hand, the aluminum content of the produced water exceeds the corresponding limit value in sanitary Standard for Drinking Water (GB 5749-2006); in addition, excessive polyaluminium chloride is added, so that the acidity of the water body is enhanced. The PAM is added too much, so that the running cost is increased linearly, and the harm to the health of human bodies is also generated. Therefore, the reduction of the addition of the coagulant and the coagulant aid has important significance for reducing the running cost of water treatment and ensuring the quality of produced water.
In addition, the accurate control of the dosage of the coagulant and the coagulant aid and the return amount of sludge containing the coagulant and the coagulant aid are effective ways for reducing the dosage of the water supply flocculant and the coagulant aid, and the current common practice in the industry depends on manual adjustment of the dosage and the return amount of sludge, so that the adjustment is not accurate enough and is not timely, and the condition of sludge recycling failure of a system is easily caused.
