Problems solved by technology

[0005] Aiming at the characteristics of unstable water output, large quality changes, complex components, and high pollutant concentration of garbage extrusion liquid in garbage transfer stations, and the problems of deodorization and deep water purification need to be solved at the same time, the present invention provides an odorless garbage transfer station. , The extrusion liquid treatment process method without solid waste discharge, using the method provided by the invention can realize that the garbage extrusion liquid effluent is odorless, tasteless, clear and clean, and can be recycled. The waste transfer station is odorless and has no solid waste discharge, which greatly improves Improve the surrounding ecological environment and benefit the residents

Embodiment 1

[0029] This embodiment is used for a daily average extrusion liquid production volume of 20m 3 / d's garbage transfer station.

[0030]The rubbish squeeze liquid emits a disgusting stench, a thick oil film floats on the surface, the liquid is turbid, and the transparency is extremely low. The quality of the raw water is COD Cr 10000~12000mg / L, NH 3 -N 200~600mg / L, TP 500~800mg / L, TN 400~900mg / L, pH 3.0~5.0.

[0031] Its technological process of adopting this invention process to process rubbish extrusion liquid is as follows:

[0032] The garbage extrusion liquid flows through the ground groove first through the stainless steel grid. The effective spacing of the grid bars is 5mm, and the grid bar width is 10mm. Continue to enter the degreasing pool (effective volume 1.0m 3 ), the length of the clapboard is 0.4m, the hydraulic retention time is 1.2h, and the floating oil is removed, and then the sewage enters the acid-base adjustment tank made of PE through the pipeline (th...

Embodiment 2

[0051] In the present invention, the system effluent is used to spray and flush the garbage transfer station and the extrusion workshop, and the odor concentration is detected before and after flushing and spraying. The results are shown in Table 2:

[0052] Table 2 Comparison before and after flushing (spraying) of garbage transfer station and extrusion workshop

[0053]

Embodiment 3

[0055] The concentration of pollutants in the garbage extrusion stock solution is too high, COD Cr The concentration is 2,500 times that of surface water Class V standard. Microbiological plate analysis of the waste extruded liquid shows that there is a very small amount of microorganisms in the liquid (about 10 3 cfu / mL) to survive, the types are messy, and there is a sour smell ( figure 2 ). The added compound microbial agent grows into dominant bacteria in the aerobic pool for 6-8 hours ( figure 2 ), inhibit the growth and reproduction of harmful bacteria, accelerate the elimination of odor, and efficiently purify water quality.

Abstract

The invention belongs to the technical field of ecological environmental protection of microorganisms, and provides an odor-free and solid waste-free squeezed liquid treatment process for a refuse transfer station. The treatment of garbage squeezed liquid is divided into two steps of deodorization and purification. After the method provided by the invention is adopted, the garbage squeezed liquidcan be treated to meet requirement of up-to-standard discharge in a short time, the effluent is enabled to be odorless, clean, clear and recyclable, and the refuse transfer station does not dischargeodor and solid wastes. Compared with other methods, the squeezed liquid treatment process provided by the invention has the advantages of no toxicity, environment friendliness, less investment, quickresponse, high efficiency, good stability, small occupied area, simple operation, convenience in management and maintenance, and the like. The squeezed liquid treatment process fills in the gap of microbiological treatment of the garbage squeezed liquid in China, enables the refuse transfer station not to discharge odor and solid wastes, and realizes the up-to-standard discharge and recycling of the garbage squeezed liquid.

Description

technical field [0001] The invention relates to the technical field of microbial ecological environment protection, and in particular to a process for treating squeeze fluids in waste transfer stations that are odorless and solid waste-free. Background technique [0002] With the development of economy, the increase of urban population and the improvement of residents' living standards, the quantity of commodity consumption increases rapidly, and the production and discharge of urban waste also increase accordingly. In order to realize the "harmless, reduction, and recycling" of garbage, the current urban garbage treatment mainly adopts three methods: landfill, incineration and composting. Due to the high content of inorganic impurities in urban waste, which affects the subsequent treatment of waste, the waste is often crushed and squeezed before being landfilled, incinerated or composted to improve the efficiency of waste treatment and save space. However, the garbage sque...
