The high turbidity problem in water out of the cyclofloc always exist in Pech?-David water treatment plant at Toulouse in France. Compared with the other water treatment plant at Toulouse, the turbidity of Pech-David was 2.3NTU and was higher than that of Clairfont as 0.5NTU. Coagulation jar-tests with several coagulants and coagulation aids from Floerger and Ciba company were studied to solve this problem.

Complex flocculant PASS has the abilities of neutralizing electric charge and flocculating. The experimental results show: it is feasible that the emulsion wastewater can be treated into qualified discharging water. The dosage of flocculants and pH value have been optimized by coagulation experiments. In addition the mechanism for emulsion wastewater has been studied by using Perron timed complex colorimetric method and neutralization method. Aiming at characteristics of high concentration and high CODCr emulsion wastewater the technology that emphasized on coagulation-precipitation twice has been proposed in this paper.

Thirty patients with acute promyelocytic leukemia were observed between September 1977 and October 1985. Bleeding diathesis with petechiae or ecchymosis (80%) was the most common presenting symptom. Seventeen of 24 patients with pretreated coagulation studies were diagnosed to have disseminated intravascular coagulation. Six out of 11 patients died from intracranial hemorrhage after a mean of 2.5 days of hospitalization without any treatment. DIC was responsible for death in most cases. Induction therapy with anthracycline and cytosine arabinoside combined with prophylactic heparin infusion was carried out in the remaining 19 patients. Two patients were incompletely treated. Eight out of 17 patients achieved complete remission after a mean of 63 days following chemotherapy. The remission rate was 47%.
