1-2 will fail, and the cost for changing a film accounts for about more than half of initial equipment investment, and user can not change at all.Middle water returns
With pollutant concentration it is low with embrane method technology be it is feasible, 4-5 changes a film.
The filtered backwashing water of film accounts for about 25% high concentration wastewater treatment of wastewater flow rate, will cause secondary pollution.
(3) three-level stirring-type chemical precipitation method:
Reaction time is long, and needing several hours even to stir, the ability of reaction in one day is complete and precipitation capacity is big.
It takes up a large area, wastes land resource.
The medicament for precipitating selection is too viscous, is not easy to filter, and sediment weight is big, increases secondary treatment expense.
Troublesome in poeration, operator requires horizontal high.
(4) eddy flow chemistry one-step method
This method is compared with other methods, comprising: one-time investment is few, occupied area is small, corrosion resistance is strong, operational administrative
Simply, for ease of maintenaince, the features such as equipment is removable.Automation degree of equipment is higher, and waste water is automatically drawn into, and clear water is automatically drained out,
Chemical reaction is needed to change within 24-72 hours continuous, moment completion by artificial chemistry method, and the expense for handling waste water per ton is lower, place
Water after reason can reuse, cost saved human and material resources, fund.Treated, and solids can be concentrated by local environmental protection administration
Processing, thoroughly eliminates secondary pollution.
