Embodiment 1

[0063] Embodiment 1: the device of the measurement pollution factor of the present embodiment affects the biological activity of aerobic process, consists of raw water tank 1, water inlet pump 2, water inlet valve 3, water inlet main pipe 4, six sets of sequence batch type arranged in parallel Reaction device 5, air pump 6, total air pipe 7, computer 8 and stainless steel stand 10 are formed;

[0064] The raw water tank 1 is connected to the main water inlet pipe 4 through the water inlet pump 2; the water inlet valve 3 is set between the water inlet pump 2 and the water inlet main pipe 4, and the sewage outlet 9 is set at one end of the water inlet main pipe 4; After the end of the sludge discharge port, the mud-water mixture in the reaction device is collected to the sewage discharge port through the water inlet pipeline and discharged. At this time, the water inlet valve 3 at the upper end of the water inlet pump should be closed to prevent sludge from entering the water pum...

Embodiment 2

[0106] Embodiment 2: Utilize the device of embodiment 1, measure the method for polluting factor to the short-term impact rule of aerobic process biological activity, carry out according to the following steps, wherein polluting factor is different metal ions, and aerobic process is CANON process:

[0107] 1. Number the six sets of reaction devices 1 arranged in parallel, respectively No. 0, No. 1, No. 2, No. 3, No. 4 and No. 5;

[0108]According to ammonia nitrogen concentration of 200mg / L, nitrous nitrogen concentration of 0mg / L, nitrate nitrogen concentration of 0mg / L, alkalinity of 1600mg / L and total phosphorus concentration of 15mg / L, 942.86mg / L of (NH 4 ) 2 SO 4 , 2685.31mg / LNaHCO 3 and 65.81mg / LKH 2 PO 4 Add water to dissolve, then add inorganic salts and trace elements necessary for microbial growth, of which the inorganic salt is 150mg / L MgSO 4 ·7H 2 O and 68 mg / L of CaCl 2 ;Trace element is 5mg / L FeSO 4 , 0.43mg / L ZnSO 4 ·7H 2 O, 0.24mg / L CoCl 2 ·6H 2 O, ...

Abstract

The invention discloses a device and a method for measuring the influence rule of pollution factors on the biological activity of an aerobic process, relates to the device and the method for measuringthe influence rule of the pollution factors on the biological activity of the aerobic process, and aims at solving the technical problem that the existing device for testing the influence of microbial activity has single pollution factors and indexes. The device comprises a raw water tank, a water inlet pump, a water inlet valve, a water inlet main pipe, a plurality of sets of in-parallel reaction devices with the same structure, an air pump, a main air pipe and a computer; wherein the raw water tank is connected with the water inlet main pipe and is led into each reaction device; the air pump is connected with the main air pipe and leads into each reaction device. According to the method, different pollution factors are added to each reaction device, and the pollution indexes are sampledand tested during operation until dissolved oxygen is mutated to obtain the optimal hydraulic retention time and the short-term influence rule. Taking the optimal hydraulic retention time as an operation cycle and operating for at least 22 days, the long-term influence rule is obtained. The device and the method can be used in the technical field of sewage treatment.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a device and a method for measuring the influence of pollution factors on the biological activity of an aerobic process. Background technique [0002] In sewage biological treatment, according to the difference of oxygen supply mode and microbial community, it is usually divided into two categories: aerobic and anaerobic processes. The aerobic process refers to the process in which microorganisms use pollutants in water as substrates to be removed through aerobic metabolism in the presence of oxygen. Compared with the anaerobic process, the aerobic process has the advantages of rapid microbial proliferation, high treatment efficiency, and good effluent quality. Therefore, the aerobic process represented by the activated sludge process has been widely used in the treatment of urban domestic sewage and industrial sewage. Wide range of applications.
