[suitable scope]
Apply to the sewage processing such as uptown, restaurant, guesthouse, sanatorium, school, mine, factory and similar industrial sewage disposal.
[equipment characteristic]
But below embedded the earth's surface, full automatic control, do not need personnel administration, without mud circumfluence, the operation is simple, safeguard convenient noise low, without peculiar smell, service life is long
[model norms]
[WSZ-A module type]
One, craft explains
The design of WSZ-A equipment basically is to be aimed at sewage to mix to it similar industry the processing of organic sewage. Its basically handle a method is to use at present —— of relatively mature biochemical treatment technology contacts oxidation law, water quality parameter presses water quality of average life water, enter water BOD 20Omg/l, give design of index of water BOD 20mg/l, in all portion of the six ministries in feudal China comprises: (1) Chu Chenchi; (2) contacts oxidation pool; (3) 2 deep pools; (4) disinfects device of pool, disinfection; (5) mud pool; (6) fan room, fan;
Discuss as follows respectively now:
(1) Chu Chenchi: Heavy Chi Weishu sheds type sedimentation basin at the beginning of equipment, sewage is 0.6-0.7 millimeter in the ascendant velocity of flow of sedimentation basin / second, the mud that precipitation comes down uses air to carry to mud pool. (note: WSZ-A O.5-5m3/ H does not set Chu Chenchi)
(2) contacts oxidation pool: Do as one pleases of the water after sinking first undertakes biochemical treatment to osculatory pool, osculatory pool cent is 3 class, total retention period is 1 hour of above. Strengthen model time of equipment contact oxidation can amount to 6 hours, filling is novel echelon filling. Easy conjunctiva, do not jam. Filling is 160m than expressing an area2/ M3, osculatory pool air-water is compared in 12:1Or so. (note WSZ-A 0.5-5T/h, osculatory pool is 2 class)
(3) 2 deep pools: The sewage after biochemistry sheds 2 deep pools, 2 deep pools set upright sedimentation basin drifting type for 2, their paralell connection moves. Ascendant velocity of flow is O.3-0.4 millimeter / second. Platoon mud uses air promotion to come mud pool. (note WSZ—A0.5-5mT/h, mud do as one pleases arrives in mud pool)
(4) disinfects pool and alexipharmic device: Alexipharmic pool presses a standard: “TJI4—74” standard is 30 minutes, if hospital sewage, disinfect Chi Kezeng to add retention period to 1-1.5 hour, use solid chloric the alexipharmic means with a deliquescent contact, the size that alexipharmic device can measure according to giving water is changed ceaselessly add dosage, achieve many water to add medicine more, give water less to add medical purpose less. Other disinfects device to be able to be made up separately. (note: Does condition of of of Chang of drop of ひ of Xie Mei Quan subtle is circle of every tip of pa of arsine chew grey?
