Embodiment Construction

[0018] Referring to the accompanying drawings, specific embodiments of the present invention will be described in detail.

[0019] Such as figure 1 As shown, in the sewage flocculation and sewage system of the prior art, sewage and flocculant are input into the tank according to a certain constant ratio, and the mixer mixes and flocculates it at a fixed speed, and then it will be determined according to experience During downtime, the supernatant liquid is pumped out and stored externally, while the flocculated dirt at the bottom of the tank is drained and closed by manual opening.

[0020] Such as figure 2 Shown is a specific embodiment of the sewage flocculation sewage system of the present invention. It differs from existing technologies such as figure 1 The difference between the sewage flocculation and sewage discharge system shown is that the present invention uses two-stage water quality monitoring, that is, the central processor monitors the water quality of the se...

Abstract

The invention provides a sewage flocculation and blow-down system and belongs to the technical field of sewage treatment. The sewage flocculation and blow-down system comprises a sewage and flocculating agent leading-in pipeline (1), a tank body (2), a bracket (3), a double-grade agitator (4), a water collection groove (5), an overflowing groove (6), a spiral umbrella-type cover body I (7), a spiral umbrella-type cover body II (8), a precipitator (9), a water quality monitoring device, a dirt collection barrel (12), a centrifuging drying machine (13) and an equipment adjusting central processor. The sewage flocculation and blow-down system can be used for realizing fixed-period automatic control blow-down so that the flocculation and blow-down system can be prevented from being frequently started and stopped and a liquid supernatant can be continuously overflowed and stored.

Description

technical field [0001] The invention relates to a sewage treatment system, in particular to a sewage flocculation sewage discharge system. Background technique [0002] In the field of sewage treatment equipment technology, most of the flocculation and sewage treatment systems used in my country's sewage treatment are designed according to the characteristics of traditional flocculation water purification. It is manually implemented after shutdown, and the technical method is backward. The existing flocculation and sewage discharge technology usually results in unstable quality of the flocculation supernatant, untimely discharge of sewage and inability to continuously self-control the supply, etc., which are specifically reflected in the following points: [0003] (1) In the traditional sewage flocculation sewage system, since the equipment mechanism is mostly limited by one-time operation, it is impossible to timely control the sewage entry, flocculant addition and sewage d...
