A few minutes will discharge substantial amounts of backwash draining, can neither flow back, and also do not allow to be directly discharged into river and apply retention it is therefore necessary to add
Just allow after pollutant to enter river nearby, need to spend great amount of investment expense.
2nd, use the problem of aspect：
1st, quartzy sand filter use in the less sewage treatment plant of scale less；
2nd, the Con trolling index of discharge standard water quality low it is considered that need not；
3rd, the investment of quartzy sand filter is larger, and operating cost is high, and operation management bothers；
4th, environmental emission requires gradually to carry mark, and industrial boom leads to part industrial wastewater to enter sewage treatment plants,
Original handling process is difficult to bear different impact loads, makes COD（COD）、TN（Total nitrogen）、TP（Total phosphorus）Exceeded
