Problems solved by technology
[0018] (1) Disc-type filter press device: the volume of filtrate after press filtration is large, the filtration pressure is high, and the energy consumption is high; the operation is troublesome and the efficiency is low; the filter cake is not scraped clean, and the moisture content is uneven;
[0019] (2) Dual heat source sludge dryer: complex structure; additional steam boiler is required, high investment;
[0022] "An activated biomass charcoal adsorption tank system CN201520269235.0" and "An activated biomass charcoal adsorption bed CN201520269245.4" invented by the applicant disclose two kinds of single adsorbers using activated biomass charcoal as the adsorbent. body structure, but does not involve the origin of activated biochar, nor the destination of biochar saturated with organic matter, and has not formed an industrialized production chain

Embodiment Construction
[0036] specific implementation plan
[0037] The present invention is achieved through the following technical solutions:
[0038] see figure 1 In the present invention, the sewage with a moisture content > 97 is removed through the thick and fine grids and the grit chamber to remove impurities and grit, and then pumped to the adsorber for adsorption, and the effluent is sent out according to the standard.
[0039] A further scheme of the present invention is to dry the sludge charcoal saturated with organic matter and dry it in a low-temperature air-drying oven until the reclaimed sludge charcoal with a moisture content of about 15% is sent to a granulator for granulation.
[0040] The applicant of the low-temperature air-drying furnace applied for another case, which is a kind of air-drying furnace that uses circulating hot water to go through the pipe as a heat source and simultaneously sends in low-humidity air.
[0041] The granulator is a step-die granulator.

The invention discloses a novel sewage treatment process using self-produced sludge carbon as an adsorbent and a carbon-water ratio determination method. The self-produced sludge carbon is used for replacing activated carbon for water treatment. And the sludge carbon rich in organic matters is used as a raw material and is carbonized again for cyclic utilization. Capital construction investment is saved, occupied area is small, operation cost is low, efficiency is high, and impact load resistance is high. The method is a novel sewage treatment process which has a development prospect, is sustainable, can be popularized and can be duplicated. The COD (Chemical Oxygen Demand) fluctuation of raw sewage in different industries is very large, and the discharge standards of treated sewage in different industries and different areas are different. Therefore, the carbon-water ratio g / m < 3 > is obtained by a carbon-water ratio test mode according to the COD value of the raw water and the COD value of the sewage required to be discharged. Therefore, the invention provides a method for determining the carbon-water ratio, which is used for implementing the economic effect of the invention.
Description
technical field [0001] The invention relates to a sewage treatment process and a method for measuring the ratio of carbon to water using sludge charcoal as an adsorbent. Background technique [0002] Sewage treatment is a comprehensive technology with high energy consumption. For a period of time, high energy consumption and high operating costs have hindered the construction of urban sewage treatment plants in my country to a certain extent, and some of the completed treatment plants have also been in a state of shutdown or semi-stop production due to energy consumption. For a long period of time in the future, energy consumption will become the bottleneck of urban sewage treatment. Whether it can solve the energy consumption problem of the sewage treatment plant and carry out reasonable energy distribution has become a key factor in determining the operation efficiency of the sewage treatment plant. Low energy consumption is also a decisive factor in the feasibility anal...
