The combined process has the advantages that the occupied area can be saved, the flow is optimized, the production water consumption is reduced, the automatic management level of the water plant is improved and the remarkable advantage for ensuring the water quality of the effluent is obtained.
Description
Technical field
The utility model is a kind of water treatment device that relates in the water supply engineering; Specifically be applied to handle the water treatment device of the bigger former water of turbidity luffing; To the big characteristics of raw water turbidity variation range, with pre-treatment, conventional processing, advanced treatment and the optimum combination of reuse water treatment process.
Background technology
In north China, there is the bigger earth surface water source of some turbidity variation ranges, like the Yellow River header section, the turbidity rangeability is between 32 ~ 25000NTU, and luffing is very big.At present, handling similar former water treatment process commonly used is the conventional treatment process of settling pit+mechanical accelerating purifying pool+conventional rapid filter.Wherein, single pond scale of mechanical accelerating purifying pool is generally 2 ~ 30,000 m
3/ d, relatively poor relatively to the suitability of big-and-middle-sized water factory.And single pool area of conventional rapid filter is also less relatively, and only adopts single water recoil developing result relatively poor, and it is also relatively poor relatively that filter bed contains dirty ability.In addition, this technology not to mechanical accelerating purifying pool spoil disposal water and filter tank recoil water collect, processing and reuse, water factory's water loss is bigger.
Though above-mentioned technology has comparatively sophisticated service experience in north China, its treatment effect is general, and water factory's water loss is bigger, and automatic management level is lower, is difficult to satisfy the processing requirement of modernized Large Water Works.
The utility model content
The purpose of the utility model is to provide a kind of water treatment device of handling the bigger former water of turbidity luffing; Be suitable for the big-and-middle-sized water factory that raw water turbidity changes the larger area, solve the problem that conventional art breading effect is relatively poor relatively, the process water consumption is higher relatively, automatic management level is relatively low.
To achieve these goals; The technical scheme of the utility model is: a kind of water treatment device of handling the bigger former water of turbidity luffing; It is characterized in that this device comprises the water inlet pipe network that connects successively, efficient settling pond, homogeneous filtering material air-water backwashing sand filter, lift pump room, back ozone contact tank, gac sand filter, clean water basin, conveying pump room and the distribution system of water supply; The waste water output terminal of homogeneous filtering material air-water backwashing sand filter is connected with the input terminus of backwashing wastewater equalizing tank, and the output terminal of backwashing wastewater equalizing tank is connected with efficient settling pond.When if turbidity is higher, between water inlet pipe network and efficient settling pond, also set up a settling pit, carry out preliminary sedimentation.When if turbidity is low, then the spoil disposal water output terminal of efficient settling pond also is connected through concentration basin, reuse water liquid storage tank and efficient settling pond successively, and spoil disposal water is carried out reuse.
Former water adopts at first that efficient settling pond mixes, flocculation and precipitation process; Water outlet gets into homogeneous filtering material air-water backwashing sand filter and filters; And then be promoted to through pump house and get into the gac sand filter after the ozone contact tank oxidation of back and filter, filter back water is sent into the distribution system of water supply through the clean water basin back of regulating and storing by the conveying pump room.Reuse is to the settling pond mixing zone behind filter back washing wastewater collection to the backwashing wastewater reuse pool.The utility model changes to raw water turbidity, switches through valve, adopts different treatment process.When raw water turbidity is low (500NTU), former water directly gets into the conventional processing system, and spoil disposal water and filter back washing waste water are implemented to handle reuse; (500 ~ 1500NTU), former water directly gets into the conventional processing system, but only filter back washing waste water is implemented to handle reuse when raw water turbidity is medium; (> 1500NTU when raw water turbidity is higher), former water need be introduced into pretreatment system, and reuse filter back washing waste water only.
The advantage of the utility model is to the bigger characteristics of raw water turbidity variation range; Adopting efficient settling pond, homogeneous filtering material air-water backwashing sand filter and ozone and activated carbon filter tank, back is core process; Pre-treatment, conventional processing, advanced treatment and reuse water treatment process are optimized combination, make its adjustable running pattern under different raw water turbidities, under the prerequisite that guarantees effluent quality; Optimized treatment scheme; Reduce water factory and produced the water consumption, and available factory effluent has been carried out reuse, effectively improved former water use efficiency.The advantage of this combination process is and can saves the area, and optimizes flow process, reduces and produces the water consumption, improves the water plant automation level of management, and to guaranteeing that effluent quality has remarkable advantages.
