Embodiment Construction

[0034] The water quality of the influent is monitored in real time through the online water quality monitoring system, and relevant information is fed back to the computer automatic control system, and the module combination and operating parameters that should be selected under the water quality conditions are determined according to the set computer program.

[0035] When the water level difference before and after the grid of the pretreatment module I is H≥1.25m, adjust the water inlet flow pump, and adjust the flow velocity v to be below 0.7 m / s; when the water level difference before and after the grid is H≤0.6m, adjust the water inlet flow pump, and pass the grid The flow velocity v is adjusted to above 1.1 m / s.

[0036] When the primary physical and chemical module II enters water: c(SS)18.5mg / L, run [coagulation-intermittent air flotation-sedimentation-regulation] module, adjust pH=7.8~8.5, add agent PAC (50mg / L )+0.1%PAM (2mL / L); In addition to the above conditions, run...

Abstract

The invention relates to a modular integration method suitable for treating slaughter workshop wastewater. A system adopted in the method is composed of a pretreatment module, a primary physicochemical module, a secondary biochemical module, a tertiary deep treatment module and a solid residue anaerobic fermentation module. The pretreatment module is a grating; the primary physicochemical module main has adjustment, coagulation, precipitation, air floatation and cyclone centrifuge functions, above functions are integrated in a same reactor, and an air floatation unit adopts an intermittence dissolved air floatation technology; the secondary biochemical module is mainly provided with an EGSB unit and a CASS unit, and the EGSB unit and the CASS unit are serially arranged; the tertiary deep treatment module is mainly provided with an O3 oxidation unit and an active carbon adsorption unit, and the O3 oxidation unit and the active carbon adsorption unit are serially arranged; and the solid residue anaerobic fermentation module is mainly used to collect grating and air floatation discharge residues and residual sludge of the biochemical module. The method adapts to the small, fast and scattered characteristics of slaughterhouses in China, can effectively solve the problem of treatment of distributed slaughter wastewater, and is intelligent, modular and integral.

Description

technical field [0001] The invention relates to the technical field of integrated treatment of high-concentration organic wastewater, in particular to a modular integrated process method suitable for treating wastewater from slaughterhouses, aiming at the problem of difficult treatment of wastewater generated in the production process of small slaughterhouses. Modular, intelligent and integrated. Background technique [0002] The slaughtering industry is one of the pillar industries that guarantee supply in our country, and it is also one of the largest sources of organic pollution in our country. Most cities in my country have basically realized fixed-point centralized slaughtering, but there are many scattered small-scale slaughterhouses and even private workshops in vast small towns and rural areas. These slaughtering sites are out of the sight of the supervision, with strong concealment, poor equipment and facilities, and difficult to implement the operation specificati...
