Embodiment 1
[0094] Embodiment 1, a kind of comprehensive treatment method of amprolium hydrochloride high-concentration organic process wastewater, this amprolium hydrochloride high-concentration organic process wastewater is the high-concentration organic process produced in the production process of anti-coccidiosis veterinary drug-amprolium hydrochloride Waste water (as shown in table 1); Carry out following steps successively:
[0095] 1), 10,000ml of amprolium hydrochloride high-concentration organic process wastewater (COD is 110,000mg / l) was cooled to 0°C with ice-salt water, and naturally settled for 12 hours to separate 200ml of organic phase and 9,800ml of water phase.
[0096] The 200ml organic phase was concentrated under reduced pressure at a vacuum of 0.09Mpa and a temperature of 55°C to obtain 60g of amprolium hydrochloride intermediate 4-amino-(5-methoxymethyl)-2-propylpyrimidine and chloroform 160ml.
[0097] Therefore, in actual application, the organic phase is directl...
