A kind of novel industrial water supply treatment unit
Technical field
The utility model relates to Water feeding treatment device, particularly a kind of novel industrial water supply treatment unit.
Background technology
At present, for the device of removing hardness in industrial water supply, there is lime reaction+inclined tube/sloping plate deposition+clarification+filtration.Its shortcoming has: the first, floor space is large; The second, invest high; Three, operation and maintenance is difficult.
Summary of the invention
The purpose of this utility model is to provide a kind of novel industrial water supply treatment unit, use water suspension content and be less than 5mg/L, turbidity is less than 3NTU, total hardness is less than 100mg/L, reach the indices requirement of industrial water supply, with reduced investment, floor space is little, stable effluent quality is up to standard, be convenient to management and operation, can realize the object that automatization is controlled completely.
Formation of the present utility model: a kind of novel industrial water supply treatment unit, by mixed reaction pond, high turbidity integrated water purifier, sludge sump, pressure filter, sterilizing unit, acid adding device, PAM chemicals dosing plant, PAC chemicals dosing plant, soda ash solution preparation facilities, lime emulsion preparation device, and be aided with PH, liquidometer, turbidimeter, chlorine residue on-line monitoring instrument, it is characterized in that: former water enters mixed reaction pond by water inlet pipe, mixed reaction pond adds pipe by lime solution and adds pump with milk of lime and be connected, mixed reaction pond adds pipe by soda ash solution and adds pump with soda ash solution and be connected, mixed reaction pond is connected with PAC chemicals dosing plant by PAC chemical feed pipe, mixed reaction pond is connected with high turbidity integrated water purifier by mixing water water inlet pipe, mixing water water inlet pipe is connected with PAM chemicals dosing plant by PAM chemical feed pipe, high turbidity integrated water purifier adds pipe by acid and is connected with acid adding device, high turbidity integrated water purifier is connected with sludge sump by high turbidity integrated water purifier shore pipe, high turbidity integrated water purifier water outlet drains into factory's water reservoir by high turbidity integrated water purifier rising pipe, high turbidity integrated water purifier rising pipe adds pipe by sterilizing agent and is connected with sterilizing unit, sludge sump enters mud pipe by pressure filter and is connected with pressure filter, sludge lifting pump is connected with sludge sump, lime emulsion preparation device adds pump with milk of lime and is connected, soda ash solution preparation facilities adds pump with soda ash solution and is connected.
PH on-line monitoring instrument is installed in mixed reaction pond (1), PH on-line monitoring instrument, liquidometer, turbidimeter are installed in high turbidity integrated water purifier (2), water outlet is provided with chlorine residue on-line monitoring instrument.
Compared with the prior art, advantage of the present utility model: the first, adopt three sections to remove hardness reaction, removal efficiency is high, and adding of agent is few; The second, adopt high turbidity integrated water purifier to carry out separation, operating performance is good; Three, a whole set for the treatment of unit is easy to carry out automatization control, is convenient to Operation, Administration and Maintenance; Four, this plant investment is economized, and working cost is low, and floor space is little.
